The AI cheats to all hell. Dice rolls are not random, they're pre-determined. It seems to be related to how you bet. I lost a good 23 times against Thaler, then changed my betting strategy and never lost again, got 12,000 orens out of him - If you think that's luck, I have a bridge to sell you. To beat Thaler, bet maximum to begin with (++), then raise medium (+). Don't do anything stupid, always raise medium, play a good game and you'll win, the game will automatically give you a hand to beat anything he throws. In one memorable game, he threw five fives, i re-rolled all five dice and got five sixes.This doesn't work against Heirophant, still looking for something that does. Luck plays absolutely no part in dice poker. The game may also re-generate the "winning combination" between sessions, but does not between saves and loads. Keep trying until you win, then bet exactly the same way next time.
