 If he is correct, he puts the hand down on his side of the table and picks up another hand.If he does not have a Krypto, you can either just return the hand face down to the table with no penalty or you can penalize the false Kryptoer by subtracting one hand from his total at the end of the round/game.At any time, either player may return his hand face down to the table and pick up another one - as often as he wants.
