To play, send a note mentioning this account and then zap the "game note" reply. You can also modify the payout by including a number (1.5 - 100) after the mention. For example the note: "@dicer 5" will start a game with a 5x payout. Fairness: TLDR: When a game note is zapped, a random number is fairly generated and the game is won if that number is less than a value dependening on the game's payout odds. Detailed Explanation: The game note commits to a "fair preimage" by including its SHA256 hash as the note's "hash" tag, and the note commits to a probability of winning by including a "u32odds" tag. When the note is zapped, we compute the SHA256 hash of the zap request note signature ("sig_hash"), which is unpredictable and non-malleable. The "outcome" is determined by interpreting the first four bytes of the bitwise XOR between the fair preimage and the sig_hash as a little-endian unsigned 32-bit integer. If "outcome" is less than or equal to "u32odds" then it is a win. A zap may be initiated for a game note only a single time and only by the original poster. After a game note is zapped, a detailed breakdown of the outcome is DMd to the zapper.
