Hi there again,

This time I'm presenting a site that is mostly for illustration purposes, you can access it at provablyunfair.com but you can't play with bitcoins there.

What's the deal there ? Very simple, you get to play a game with 50% chance to win, except that it has a very simple form of pattern matching. It will try to guess your next bet, after some initial bets. How many games can you play before getting a horribly low win ratio ? The next result is known in advance, which you can check after each game.

What's the point of this thing ? This is an illustration of why one has to take care when betting (like if gambling games being -EV wasn't enough) at some places. It is possible that in the future there will be other illustrations, for now there is just this simple one there.

What data is being collected ? The only data used are the bets you placed after visiting the site. If you reload the site, that data is erased.

Enjoy!


EDIT: Forgot to mention that I can arrange ads to be placed there, provably unfair casinos might get a good deal with that domain.

[Patten]

Patten is a new game that is just being launched for the public. This is a simple game that combines betting on 50% game with patterns and jackpot. A pattern is continuously built after each bet, and the player can affect it to help hitting specific patterns to grab the jackpot.

Distinctive features:

• Patterns and jackpot

[GGDICE]

Hello everyone,

Recently I've been working on https://ggdice.com and now I would like to invite you all to visit it. It is still in alpha, but since I won't be modifying it (too much) in the next weeks, I thought now would be a good opportunity to announce it. Suggestions, critics and questions are all welcome. A current, and not so short, description of the site follows:

GGDICE

GGDICE is a place where you can do provably fair dice rolls with your favourite crypto currency in varied rooms. The system is composed of several rooms, where each one of them uses a single coin and has its own settings like room edge and bet risk (for the investor^**). For the moment there are three rooms (all owned by the house and all with the same game type):

• The default room where new users start at with 1000 FakeCoins and play at 1% edge
• The Litecoin room with a 0.8% edge which currently supports bets giving a maximum profit of about 1 LTC
• The Bitcoin room with a 0.8% edge and current max profit of about 0.03 BTC.

Deposit your coins and play!

There is support for executing strategies in the server, limited to 10 thousand rolls per strategy with a throughput of about 300 rolls per second given the current server. More details about this can be seen in the site by visiting the "Strategy" section found in the menu at right. The profit plot will show a single point for a given strategy, which regards the profit generated by its complete execution.

Your bets can be downloaded at any given point, and the download link can be shared with others till it expires. There are some hidden features which can be accessed by typing "/help" in the chat, as well some shortcuts that are not described anywhere: "B" toggles the bet panel, "M" toggles the right menu, "T" switches between the strategy page and the main page, "F1" (funny suggestion by someone) sets the bet according to the maximum profit for the room.

The login method follows the more or less traditional method of automatically creating a new account when you first visit the site. If you lose the received cookie, you can no longer access the account.
To avoid this problem you can either setup a username/password pair or use OneID. The former is not recoverable; the later is much safer for everyone involved, simpler to use, and you can configure it yourself whether you want 2FA or not.

Other details:

• The layout looks like a mobile thing because I started the site with focus on mobile
• The live bets are always slightly delayed, so if you are betting and want to see your own bets without delay, switch away from it
• Talking too fast in the chat will get you a temporary ban of a few minutes. If you want to spam the chat, wait a little bit before talking again If someone is interested in moderating it, enter in contact
• There is a basic bot for reference at https://bitbucket.org/knowitnothing/ggdice_client/src/

If you want more details, just ask. Lastly, there is a chance that parts of the server-side code will be open sourced. This chance increases if I notice I cannot support user issues, which right now I cannot. Thanks for reading, enjoy the site.
