Cheat is the classic bluffing game — play cards face-down and declare a rank, lying when you can get away with it. Get caught and you take the pile.
Deal all cards evenly. Players play cards face-down in rank order, declaring what they are.
You may play any cards regardless of what you declare. Another player can challenge by saying "Cheat!" If you lied, you take the pile; if you told the truth, the challenger takes it.
The first player to empty their hand wins.
Yes — Cheat, I Doubt It, and Bullshit are all the same bluffing game.
As many as you declare — typically one to four of the same rank.
