Just played all my 3 tries and got one wrong between $1000 & $32000. Each time I selected submit score rather than play again, then left the game. Seemed to work OK for me. In tournaments anything out of the ordinary will cause a score of 0 to be recorded. I have no idea what happened when you played, but it does work OK.
Worked fine for me. Chickened out at $4K but using it as a banker will wait for my most worthy oponenet before having another go.
