6  Alternate cryptocurrencies / Service Announcements (Altcoins) / [ETH] Matching Ethers Settings : Round size on: May 08, 2016, 11:20:26 AM
In the game matching ethers, a certain number of ppl have to join the round, before it is randomly resolved.

The settings can be adjusted to fit the like of the community.

Small round would make the game go quicker but with more variance in the % of flipped coins in each round.
Big round, will average the % of flipped ethers in each team but will take longer to resolve.

What do you prefer?
7  Alternate cryptocurrencies / Service Announcements (Altcoins) / [ETH] MATCHING ETHERS - Gambling Game BET UPSIDE OR FLIPPED on: May 06, 2016, 06:32:51 PM
Hello folks,

Let me introduce a new Ethereum game, I just launched with a full real-time website :


Ether Game Mode : (play for 1 ETH)

Finney Game Mode : (play for 0.1 ETH)

It's a strategy and luck based game derived from the old (game-theory) classic Matching Pennies.
There are 2 game modes, each with its own contract, you can play for 0.1 ETH and for 1ETH.

To play Matching Ethers, when you send your bet, you also have to choose if you want your coin to be upside or flipped.

The game is round based (average size of 18 for now), and depending on when you enter the round, you will be assigned  to one of 2 teams : the matchers and the contrarians.

At the (random) end of the round, each matcher will be (randomly) paired with a contrarian:
If both bets are on the same side, the matcher wins.
If the sides of the bets are different, the contrarian wins.

Now the thing is that the latter you enter the round the more information you have and have increased chance to win. To counter this, the game implements an information cost (deduced from winner payout) that increases with the order of entry in the round. First 2 players in round have 0% info cost, Player 3 and 4 will have a 0.5% info cost, Player 4 and 5 will have a 1% info cost ... This also serves as a small house fee (~1% on average) (to pay for domain/server/time).

You can play several times per round, so don't hesitate to try out some elaborate strategies !

How to play ?
Directly :
- send exactly the value of the bet to place it upside.
- or send (a bit) more to flip your coin ! (any excess is refunded immediatly)

Via mist :
Import the contract (using the ABI provided in the links below) and use the play function.

Please don't hesitate to give me your feedback on the game and possible improvements.
I have made the contract in a way that I can easily adjust the parameters after each round to improve the game experience depending on the community feedback. We can adjust the min and max size of the rounds, the value of the bet, the information cost ...

Have fun and Good Luck Smiley !


Ether Game Mode : (play for 1 ETH)

Finney Game Mode : (play for 0.1 ETH)

Ps: The website takes rougly 15 secs to load, it's on a low cost server (~0.5 ETH per month at actual price), I'll update the server if the game is successful Smiley
