Is the game provable fair? Yes. The algorithm uses a secret key revealed every 10 games, but also data from the race itself that cannot pe precomputed like the timestamp of the block the transaction was included and many other. This way you'll be sure the game is fair and does not try to favorize a rat over another. How to compute the speed? Example(New way - from game no. 365): ServerSeed: 3b7fecbc10005334c0b98b2bcd1ace46407094ab Gameid: 666 We take the rats and order them alphabetically. We'll use only the first 8 letters. Rat1:1AAAAAAA(10+d21) Rat2:1BBBBBBB(11+d22) Rat3:1CCCCCCC(10+d24) Rat4:1DDDDDDD(10+d25) Rat5:1EEEEEEE(10+d15) We take all timestamps when the transactions are included in blocks and order them from low to high. 111222333444555 Let's compute the speed for the first rat which runs 10+d21.

If that is not enough, the player with the greatest exp wins. Example(Old way - up to game no. 364): ServerSeed: 3b7fecbc10005334c0b98b2bcd1ace46407094ab Gameid: 666 We take the rats and order them alphabetically. We'll use only the first 5 letters.
