While playing the game, I had 0 cards on the board and 0 cards on hands but the game didn't finalize itself automatically. I had to press the Give up button, as the match should be considered finished and ended automatically. 

Imagening the scenario of betting hertz or ntfs, I could just stay like that if I didn't want to finish the game in order to avoid loosing what I bet, so game should be finalized automatic.
