Bitcoin Kamikaze is a minesweeper-like Bitcoin gamble site. They host a fun little game where you bet your chosen amount of Bitcoin and choose one of five cells, one of which contains a mine. If you step on a mine, you lost your bet; if you don’t, you can either cash out or try again and increase the stake.
In this video I play the game for a bit, and then prove their fairness. They give you a SHA-256 hash, and you play the game. After you stepped on a mine or cashed out, they give the original data string of the hash which contains the cells that had mines in them. Watch the video and see for yourself that their game is 100% open, as Bitcoin games should be.
