If you notice your Chips didn't get cashed out correctly following an unexpected end to your poker session, have no fear. The chips are not lost. To recover them, simply return to the poker room, and any pending Chips from a previous poker session will automatically be cashed in for Coins.
So, if you think poker failed to give you the Coins you won, you may be right. Just return to the poker room to collect.
If the game ends unexpectedly, any Chips you have wagered are lost. The game will treat a loss of connection or failure as a fold, as far as the game results are concerned.
