Liar

How to play

1. Play face down

   Put one or more cards into the pile and declare that they match the required rank — truthfully or not.

2. Believe or challenge

   Any other player may call you a liar before the window closes. A challenge turns the cards over.

3. Lose the bluff, take the pile

   The wrong side of a challenge picks up the pile. Get rid of every card to win.
