The game crashes fail verification. On the FAQ is stated: "Since BitCrasha is provably fair, you can verify that yourself https://jsfiddle.net/1L1uqcgv/6/embedded/result/" When you actually do that for game 1099385[1] (the latest game at the time of writing) with hash 8a1fccd8eb96d97ee7bee904878502f5a339c57c6381b8c802b17044f6f9f3a8 then it should've crashed at 1.42x but it actually crashed at 9.07x.
