Ultimate liar is a popular Finnish card game (valepaskahousu in Finnish). It is to great extent a game of skill. Cards are played face down and players do not need to be truthful when placing cards. However the others can always check.

Game enables selecting different strategies and presents challenging choices: do I save lies to the end or use them to build better hand, what strategies others are using, do I save valuable cards to the end or secure optimum hand size, do I dare to check evident lies even with thick discard pile, could this 6th Ace still be true and who is lying...

Try it out. Can you beat the computer players?

Game of S***head is a derivative of this Finnish game.
