All of the rules of the „STACK” variant apply. Additionally, during the game the participants can use the words „STOP-SHOW”. This means that the participant that has called out the recurring symbols and laid his card with it on the stack has to prove that the named symbol is really present on his card and the card in the middle of the table. If it turns out to be untrue, then as punishment for being dishonest, the cheating player takes five cards from the stack. If it turns out that there was no foul play, for his false accusation the player that has said the words „Stop-SHOW” takes 2 cards from the stack. The game continues.
If a game master was chosen, he may be the one to check the honesty of players.
