21  Economy / Services / Android programming help, will pay in BTC on: June 12, 2012, 07:32:16 PM
I'm teaching myself Android programming and have a simple app I'd like to do as a first project. I'd like an experienced Android programmer to help me get up to speed for a couple hours. Willing to pay 5 BTC/hour.

22  Economy / Gambling / Dragon's Tale Tournaments (Including freerolls) on: March 13, 2012, 02:57:13 PM
I've just completed the Tournament system in Dragon's Tale and wanted to discuss it here. It's probably the most significant addition to Dragon's Tale since the Mentorship system.

How a Tournament works is an Organizer (usually an eGenesis employee, but not always) puts up a prize pool of at least 1 BTC, and divides that into prize hoppers of at least 100 Bitmill each (a Bitmill is 1/1000 BTC.) Here are some examples of prize hoppers:

  * 500 Bitmill to the player with the highest winnings in Dynasty Fire
  * 2 BTC to be split evenly among the 5 players with the highest jackpots in any fishing game
  * 1 BTC by lottery to the player that finds the most Bitmill in plants. Each Bitmil that you find is one lottery ticket.

If a tournament consisted of these three prize hoppers, then the Organizer would need to put up 3.5 BTC to fund it and put it on the calendar. Tournaments are posted automatically to the Dragon's Tale website.

Organizers can set rules for the tournament, and this is where things get interesting. Organizers will usually set several of the following limits:

  * Number of spins (wagers) that each player can make during the Tournament
  * Total amount each player can wager during the tournament
  * Amount of time the Tournament lasts. This can be a range like "Random length of time, 10-20 minutes."
  * Must hold a ticket of type X to participate
  * Must be at least Level X
  * Must be a part of one of these Mentorship families: ..., ..., ...
  * Spin and Wager limits per game, or game set.

So with a complex prize structure and bet limits, tournaments essentially change luck games into skill games. To play smart, you need to monitor how others are doing, which prize hoppers have a high reward vs. the amount of competition, and balance long-shot vs. slow & steady play.

Often I'll set up tournaments with no entry fee and very low bet limits (1 Bitmill, 100 spins) but with larger prizes (1 BTC). So the expected cost is, say, 5 BTM to do 100 x 1 BTM spins, but if 10 players are participating, 100 BTM average prize per player. I call these Tournaments "freerolls" because it's easy to get enough free Bitmill from soldier statues to participate; having a large bankroll gives no advantage.

As always, Dragon's Tale has no "playthrough requirements" or other nonsense - any Bitcoins that you receive or win are real, and you can withdraw them immediately, gift them to friends, or continue to play.

Dragon's Tale is a free download, with native clients for Windows, Linux, and OSX:

I'll use this thread to announce freerolls and other tournaments.
23  Economy / Gambling / New in Dragon's Tale: Cow Tipping on: March 01, 2012, 05:34:13 PM

Although really simple to play (click on a cow and say how much you want to bet), this is a pretty deep game: Initially you'll be able to perform just a few of 30 possible cow-tipping techniques. As you witness others tipping cows, you'll learn "facets" of those techniques. When you know at least 5 facets of a technique, you'll be able to perform it yourself, and teach it to others.

With higher bets, there's a greater chance of performing more exotic techniques including pile drivers, complex flips and backward falls.

Dragon's Tale is a free download with native clients for Windows, OSX and Linux. We'll even give you some free Bitcoins to get started. (Real, free, with no "playthrough" requirements or other nonsense.)
24  Economy / Gambling / Dragon's Tale and Seals With Clubs team up... on: January 11, 2012, 01:52:42 AM
Dragon's Tale and Seals With Clubs have teamed up to give away a total of 30 BTC this coming Sunday and Monday. This event costs nothing to enter, and you'll get to explore both games. Here's how it works:

In Dragon's Tale, find the Seal, just southeast of where you enter the game. Click on him to start the Seals With Clubs challenge. All of the challenge items are very low-stakes, and can be completed with the free Bitcoins available from Soldier Statues.

Some of the things you'll be doing include digging for coins in a garden, growing Jastaberries, sharing drinks with a friend, and finally, withdrawing some of your winnings. When you've completed the challenge, you'll be asked for your Seals With Clubs username, and entered into your choice of freerolls which will take place on Seals With Clubs on Sunday, Jan 15, 3:00 PM EST and Monday, Jan 16, 9:00 PM EST. Each freeroll tournament will have 15 BTC in prizes.

You'll need accounts on both games of course:

25  Economy / Gambling / New skill games Dragon's Tale on: November 15, 2011, 05:55:29 PM
It's been a while since I posted - Dragon's Tale is now up to 43 unique games in it's 3D multiplayer world. (92 games counting variants.)

Our latest game is analog checkers, also known as Kanivan Tak. Pieces move the same distance as in normal checkers, but they're not limited to 45 degree angles. Players agree on a wager amount, with the winner taking all. Like most 2-player games in Dragon's Tale, there is no house rake.

We've also just released Treefalls, a seemingly straightforward game where you pick leaves from any of the trees around the world. Most trees pay 95%, but every week one species secretly pays 105%, while three species only pay 85%. By clever play, you may be able to identify the magical species and play it repeatedly. More details are provided in-game at the Department of Herbal Resources.

Another recent skill game is Qing Vases, where you try to arrange vases on shelves so that identical vases form straight lines. In Qing Vases you are able to influence which vases change from play-to-play. In the variant "Ming Vases" you don't influence which vases change, but can control how many change per play. Finally, the Han Vases variant is an almost pure-luck game that plays fast, and tends to have long winning streaks. (There is some debate on whether Han Vases is pure luck, or can be played as a skill game.)

If you've never explored Dragon's Tale, download the client and join us. There are usually some friendly mentors around to give a tour, and direct you to some free Bitcoins to get started.

26  Economy / Gambling / Dragon's Tale - the gambling MMORPG on: July 13, 2011, 08:45:02 PM
It's been a while since I talked about Dragon's Tale in the Bitcoin forums, and since the Bicoin community has grown so much lately, I thought now would be a good time to introduce it to new members.

Dragon's Tale is the Disney World of gambling. It's a 3D MMORPG where every object that you can see is a game of some sort, from the buildings to the plants. In most MMORPGs your character advances by fighting - in Dragon's Tale you level up by gambling. You can grow crops, race beetles, feed ducks, or even put on a fireworks show for friends in the game. We have 35+ games, all novel: about half of these are games of chance, and half are games of skill. We'll even give you free Bitcoins to get started, no strings attached. (As in, none of the playthough nonsense that every other online casino uses - when you get a gift from any of the Soldier Statues throughout the game, it's yours to play or withdraw.) Of course I hope you'll love the game and bring some Bitcoins of your own to play.

Dragon's Tale is by my company, eGenesis. We're the guys behind A Tale in the Desert. It is built entirely around Bitcoins, and has native clients for Windows, OSX, and Linux.

Check out the website and Wiki for downloads and more details:

Looking forward to seeing everyone in-game,
Teppy ("Di")

27  Economy / Marketplace / Free Bitcoins, No Catch on: May 10, 2011, 09:06:50 PM
I've implemented a feature in Dragon's Tale, the Bitcoin-based Casino MMORPG, that gives free Bitcoins, with no catch.

As you explore, you'll come across Soldier statues like the ones shown above: Click on one and "Ask for a Gift." They'll often give a 0.01 Bitcoin gift, but sometimes a 0.05, 0.50, or even occasionally a 5.00 Bitcoin gift, no strings attached: Unlike other casinos, these are real gifts that you can immediately withdraw. Of course I hope that you'll use the gifts to experience all the unique games that we've built into Dragon's Tale, and I hope that you'll even bring a few Bitcoins of your own some day to play.

Dragon's Tale runs (natively) in Windows, Linux, and OSX, and can be downloaded here.
28  Economy / Marketplace / 1000 BTC Giveaway – Dragon’s Tale Beta Test Celebration on: January 09, 2011, 04:50:39 PM
Over the first weekend of February 6, Dragon’s Tale, the Bitcoin-powered Gambling MMORPG, will host a party to commemorate our forthcoming Beta release with a Grand Opening Party… by giving away one grand in Bitcoins!

We will be giving away 1000 Bitcoins to readers of the forum (and of course our current players) who sign up for the party and show up to help demo all our new features.

For newcomers or those of you who may not have been by since our Alpha party in October, you’ll find:

    * A modified world design with more games and more to discover.
    * New PvP (Player-vs. Player) games with no house advantage: Smart players can expect >100% return.
    * Multiplayer strategy games with no house advantage.
    * Micro-stakes games with wagers of 1/1000 Bitcoin. Play for hours with a single Bitcoin.
    * Many more skill games in which using a smarter strategy than other players have will give you a big edge.
    * Dragon’s Treasures, bundles of 100 Bitcoins, awarded based on your play.
    * A greatly expanded Level system: Completing Level Quests increases the rate that you earn Dragon’s Treasures.
    * A new mentorship program in which experienced players get rewarded for helping out new players. Even if you don’t gamble, you can still earn Dragon’s Treasures by introducing new players to the game and showing them around.

And on the day of the party, in addition to free coins, expect:

    * A world-wide treasure hunt for hidden prizes.
    * Bonuses for the biggest winners, and even a 100 BTC consolation prize for the biggest loser!
    * Scheduled raffles, giveaways, and other surprises throughout.
    * A chance to own a piece of Dragon’s Tale. Depending on turnout, we’ll be giving away ownership of a single game for a 3-month period. For that game, you are the house.

Why are we doing this?
Obviously we’d love for you to try Dragon’s Tale, fall in love with it, and tell all your friends, but we’re throwing this party because we value the input of and feedback from the Bitcoin community.

We’re trying to create something never before seen with this game. With Dragon’s Tale we’re striving to create a platform that simultaneously embodies the social recreation that MMORPGs provide as well as the excitement known to the casual - and advantage gambler… within the context of this new cryptocurrency that has caught all of our attention.

Are we trying to be something for everybody? Absolutely not. We’re trying to be something novel, exciting, and, most importantly, fun for a select group, and we while we believe that many of’s readers will be among that group, we know that’s readers won’t bite their tongues when it comes to giving us useful feedback.

As such, a significant portion of the giveaway will go to those who provide us their comments and critiques in the days after the event. We’ll be providing bounties for the best suggestions, best critiques, and more.

What’s the catch?
Simple – we want your input. This is a no-strings-attached giveaway. You will not be required to deposit any BTC whatsoever to participate, play, or win. But since we’re after your feedback, we need our partygoers to be familiar with the basic operations of the game – anyway, we hope to be way too busy entertaining to answer your questions during the party itself!

So, in order to be invited to the giveaway party, all we ask is that you log in to Dragon’s Tale sometime prior to the day of the event, and learn enough from me (Di) or one of the game’s current Mentors (Ramapithecus, Kat) to explain them to others. We’ll then flag you as eligible for the main giveaway on the 6th. We will schedule game tours and Q&A sessions over the next month, but often we’re online anyway, and are happy show you around at odd hours. We can’t offer tours 24/7 while we gear up for the party, but suffice it to say we’ll make every attempt to accommodate anybody who expresses an interest. We’re a small company but we’re fortunate enough to have volunteers from around the world, so we hope to be able to accommodate everyone’s schedule/time zone.

To sum up:

   1. This February 6th, we’ll be giving away 1,000 BTC to our current players and to members at our Beta Test Celebration.
   2. No deposit is required. You  don’t need to give any personal information – the surveys will be conducted in-game so you don’t even need to provide an email address.
   3. In order to get invited to the party, all we ask is that you first learn the basics of the game by logging in to the game ahead of time, and get familiar with some of the games.
   4. Orientations will be scheduled as demanded, and we hope to create a schedule that will accommodate absolutely everyone.
   5. Everyone who attends the party will get a party-favor (in BTC of course), and we know that the night will see some big winners.

We’re working around the clock to get ready for our party, so we’re still hammering out the fine points, but please don’t hesitate to ask me any questions in the meantime.

Hope to see you there!
29  Bitcoin / Bitcoin Discussion / Terminology for Fractional Bitcoins on: December 30, 2010, 04:28:29 PM
I've adopted the following in Dragon's Tale - is there some more accepted convention? Should we come up with some standard?

0.001 Bitcoin : "1 Bitmill" or "1 BTM"
0.000001 Bitcoin : "1 Bitmicron" or "1 BTU"

Mill seems ok, because mills are used to specify tax rates (1 mill == 1/1000th of the value of an asset.)

I don't really care for the Bitmicron abbreviation because I always read it as a British Thermal Unit, and the Greek mu symbol is hard to type. Furthermore, microns are a unit of length.

30  Economy / Marketplace / Dragon's Tale - Skill-based Games Playsession on: November 05, 2010, 04:33:27 AM
It's been a couple weeks since the last Dragon's Tale play session - in that time I've focused exclusively on skill-based games. I've done most of these games with no house edge: This means that smart players should be able to consistently make Bitcoin by playing - I think that's pretty cool. I'll introduce the first five such games in-world, in a play session:

    Saturday, Nov 6 from 4:00PM EDT (GMT-0400) until 6:00 PM

Games include the strategic fishing game Rice Pond, the spatial reasoning game Reflection, the mind-reading game Tug, Parimutuel Beetle Racing, and The Eight Treasures of Chinese Cuisine.

Dragon's Tale is a 50M+ download, so it's a good idea to download the client ahead of time:

Native clients are available for Windows, MacOS, and Linux.
31  Economy / Marketplace / Halloween Game: Werewolf on: October 29, 2010, 02:41:42 AM
I'm thinking of running the classic game Werewolf within Dragon's Tale as a Halloween event. Though we'd play for Bitcoins, the house wouldn't take anything. Here's how Werewolf works:

Three people are secretly picked as Werewolves. A werewolf knows that he is a werewolf, others do not.
Everyone else, about 10 people, are Villagers. One of the Villagers is a Seer.

Play proceeds in day-night cycles. During the day:
1. Werewolves can smell up to 1 other person to determine if they are also a werewolf.
2. Villagers can vote on a person to lynch. It takes a majority to lynch someone. Once a person is lynched, it is known whether he was in fact a werewolf.
3. The seer can scry one person to determine if they are a werewolf.

During the night:
1. Werewolves can attack. It takes 2 werewolves working together to attack.

The game ends when there are less than 2 werewolves (Villagers Win), or when there are no more Villagers (Werewolves win.) The pool of Bitcoins is split evenly among the living winners.

The game would be played within Dragon's Tale, starting at 2:00PM EDT (GMT-0400); each round would be about 10 minutes.
32  Economy / Marketplace / Next Dragon's Tale session: Friday, Oct 15, 2:00 PM EDT (GMT-0400) on: October 14, 2010, 09:01:38 PM
The last session was small, but much fun. It's especially cool being able to "meet" fellow Bitcoiners. We'll do the next one tomorrow:

  Friday, Oct 15, 2:00 PM EDT (GMT-0400) until 3:30

If you haven't tried Dragon's Tale, it's a Casino MMORPG that I'm building: Everything that you see, everything that you touch, you can bet on, either individually, or with friends. There are no traditional casino games in Dragon's Tale: No dice, no card games, no roulette wheels. However, you may come across a coconut tree and shake it: Between 2 and 20 coconuts fall; if an odd number fall, you'll double your bet.

You may climb a mountain and discover a bench next to an ornate table. In the middle of the table is a lever. Pull the lever and 5 fireworks shells launch on the other side of town: If 3 of the shells match, you win some Bitcoins. If 4 or 5 match, then the jackpot can get quite large, nearly 300 BTC for some combinations.

Or you may come across a humble garden. Grab a shovel and dig -  it turns out that the soil is rich with Bitcoins, and finding successive bundles will double, triple or more your winnings. Jackpots in the 100's of BTC are possible.

Everything takes place in a 3D persistant world powered by the same technology that runs A Tale in the Desert. If fact, for now, the way to get into Dragon's Tale is to download the ATITD client software, and when you launch it, select "Dragon's Tale" rather than "A Tale in the Desert." The client can be found on our website:

Also, you will need some Bitcoins to join the session. Bring as many or as few as you'd like.

I play the character "Di" - Looking forward to seeing everyone once again!

33  Economy / Services / Web Designer Needed, will pay in Bitcoins on: October 11, 2010, 09:40:19 PM
I'm looking for someone that can create a website for Dragon's Tale, the new Bitcoin based MMORPG casino. I'm not looking for bleeding edge technology, but a good clean design with well written copy is essential.

I'll want to see some examples of other web sites you've done. My budget for the first version is 1000 BTC.

34  Economy / Gambling / Dragon's Tale - a Massively Multiplayer Online RPG/Casino on: October 07, 2010, 02:26:16 PM
Some of you may know me as lead designer of A Tale in the Desert I think that game designers all have far more ideas than they can possibly implement, and over the years I've had my share. When I get an idea, I write it down in a file on my computer, and I periodically peruse the list.

One idea has been on that list for almost 10 years, and it's one that kept grabbing me: What if there were a truly different kind of casino that existed as a persistent world? A world where everything that you see, everything that you can touch, was in fact some sort of game. No traditional slot machines, card games, dice, but an RPG where your character advances by success at games of chance.

Bitcoins rekindled that idea, and since learning of them, I've been brainstorming such a world. In September I started coding Dragon's Tale, an MMORPG set in China, which uses Bitcoins exclusively. The game is built on eGenesis System I, the same client/server that powers A Tale in the Desert.

Earlier this week I had a few Bitcoin veterans in for an early look, and based on their feedback, I think I'm ready to open it up for another preview. I'd like to invite all of you to join me for a play session of Dragon's Tale:

    Saturday, October 9, 2:00PM EDT (GMT-0400), for about 90 minutes

You'll need the ATITD client, which can be downloaded from
Native clients are available for Windows, OSX, and Linux. You'll also need a few Bitcoins to participate.
(If you're on a slower connection, you may want to download just the "launcher", which will pull files as needed.)

I'd be glad to answer any questions about Dragon's Tale here, and look forward to meeting everyone!
35  Bitcoin / Bitcoin Discussion / Slashdot Submission for 1.0 on: July 05, 2010, 04:07:52 PM
Unless anyone else knows a Slashdot editor, I'd be willing to submit this when 1.0 is released. (More people submitting their own versions will improve the chances of hitting the front page.)

(Technology Section)
Headline: Bitcoin releases Version 0.3
Tag: Encryption
Body: How's this for a disruptive technology? Bitcoin is a peer-to-peer network based digital currency with no central bank, and no transaction fees. Using a proof-of-work concept, nodes burn CPU cycles searching for bundles of coins, broadcasting their findings to the network. Analysis of energy usage indicates that the market value of Bitcoins is already above the value of the energy needed to generate them, indicating healthy demand. The community is hopeful the currency will remain outside the reach of any government.


[Edited the "energy backed" language.]
[Eliminated the 21M number, as db suggested. Mentioning subdividing would be too wordy.]
[Incorporated some of amall's suggestions, including eliminating the passive voice in the final sentence.]
[Integrated satoshi's suggestions, eliminating the word "anonymous", mention of Hashcash, and the "developers expect" taunt.]
[Changed the closing sentence to dwdollar's " is hopeful..." language. Satoshi, are you OK with that?]
36  Economy / Trading Discussion / A Heroin Store on: June 09, 2010, 03:22:26 PM
As a Libertarian, the thing I love most about the Bitcoin project is the chance that it could be truly disruptive.

I think that drug prohibition is one of the most socially harmful things that the US has ever done, and so I would like to do a thought experiment about how a heroin store might operate, accepting Bitcoins, and ending drug prohibition in the process. We'll assume that the drug store is very high profile, and that law enforcement makes discovering the operator a high priority. We'll also assume that heroin is cheap when bought in bulk; the street price reflects the risk that street dealers must take to sell their product.

A drug dealer would set up a website that accepts Bitcoins for heroin. Orders would require a physical address for shipping. When an order comes in, the dealer would send heroin through the mail to two addresses: the address provided, and another random address. Because packages of heroin are now arriving at addresses across the country, receiving a package does not imply that you ordered it. Random addresses would be heavily reused to prevent law enforcement from making a statistical argument.

Now law enforcement could set up such a website as well, in order to discover buyers. So, the drug dealer must take half of his profits (and remember, he's already shipping 2x the amount paid for), and use them to buy heroin at other random websites, on behalf of both his customers and the random addresses that he has used.

If the post office knows that a package contains drugs, then they could send an undercover officer to deliver the mail to your door, or surreptitiously watch your mailbox to see who collects the mail, and then get a warrant to search your house to see if the package has been opened and not discarded. (IIRC, discarded materials are no longer considered in your possession.)

So, it would be important for buyers to not open any package that they suspect may contain their heroin, until they wish to consume it: they would only be in danger of possession between when the package was opened and when the contents was consumed.

Can anyone see a way to attack the store?
37  Bitcoin / Bitcoin Technical Support / Accepting Bitcoins in an online game on: May 20, 2010, 07:12:30 PM
I'm accepting Bitcoins now for A Tale in the Desert.

I'm aware that the correct way to do it is to generate a new address for each payment, but I don't yet have the code to generate new addresses in the server. (If someone could point me to such code I'd appreciate it; I spent a few minutes poking around the source but haven't found it yet.)

But let's say that I do have the means to generate a new Bitcoin address on the fly. A player tells the game client that he wants to subscribe. I generate an address and tell him "Send 2000 BTC to <address>", and then when the Bitcoins show up I credit his month of playtime.

Once I have a list of all the "throwaway" addresses that I've created, how do I then go about watching all of them for incoming Bitcoins and forwarding them to my "real" account?

What would be ideal (in my situation anyway) is for there to be a message field as part of a transaction, and then I could just tell everyone to send to my main Bitcoin address and include their character name in the message. It looks like this is supported when sending to an IP address, but not when sending to a Bitcoin address. There must be a reason for this - anyone know what that is?
