Hi everyone,
Two days ago I released
https://ether-world-cup.com, an Ethereum network game for the World Cup.
The smart-contract implementation is available at
https://etherscan.io/address/0x4c60e311d8fba04e313f7e7b3dec61b3028726d1.
The EWC is a prediction-based game where you pay one entry fee, and then log your guess of the winner of each match for the duration of the tournament (or a draw in the group stages!). Racking up streaks of correct predictions gains you momentum in the form of bonus points, and the best performing participants at the end of the tournament walk away with the prize pool.
Entry fee:
0.2018 Ether (requires Metamask on the site, or interact directly with the contract via MEW).
Barring gas costs for utility functions - placing predictions - this is the only cost associated with the game.
Fee split: 90% to prize pool, 5% to Giveth, 5% developer fee.
Prizes:- First: 40% of prize pool
- Second: 30%
- Third: 20%
- Fourth: 10%
You can join at any time, but cannot place predictions for games which have already kicked-off.
Pretty minimalist UI: screenshot attached!

Welcome to the Ether World Cup!This is a competition to determine your skills of prediction, with a charitable edge.
Although this is a soccer-based tournament, even those with no knowledge of the beautiful game can participate.
Will you make your predictions according to betting website odds?
Or just always vote for England to lose to remind them that 1966 was a one-off?
Use whatever strategy works for you (or just pick at random)! Good luck!
* Registering allows the sender to place predictions on each game in the World Cup.
* You cannot place a prediction on a game which has already occurred.
* Predictions can be made (and changed!) for games up until the designated kick-off time.
* Selecting the correct result for any given game awards the player one point.
* Selecting the incorrect result for any given game awards the player zero points and breaks any streak.
* In the first stage, a participant can predict a draw instead of an outright winner.
* Predicting a draw is not possible after the conclusion of the group stage.
* Failing to make a prediction for a game awards zero points and breaks any streak.
Streaks:* Streaks of three consecutive correct predictions award one bonus point from the third match onwards until broken.
* Streaks of five consecutive correct predictions award an additional two points from the fifth match onwards until broken.
For example, a six-streak which is then broken followed by a correct prediction gives a resulting point-array of [1, 1, 2, 2, 4, 4, 0, 1] for a total of 15 points.
* Some games in the Group Stages are played simultaneously. For streak purposes, the order is that on the FIFA match page.
Tie-Breaking:* In the event of a tie on points, the following algorithm is used to decide rankings:
- Compare the sum totals of the scores over the last 32 games.
- If this produces a draw as well, compare results of the last 16 games.
- This repeats (8, 4, ... ) until comparing the results of the final.
- If it's a dead heat throughout, the winner will be determined via coin-flip.
