Happy new year !
I changed the Random Number Generator today.
One data that nobody can precompute or know before a game is the timestamp when a transaction is included in a block.
I decided to add this info also in the algorithm.
In this way the last player(or any other player), even if he somehow hacks or know the server seed, still cannot compute in advance anything because the last piece of the puzzle for all rats will be the timestamp his transaction will be included in a block.
