Cheat (I Doubt It): the bluffing game that needs nothing but nerve

How cheat works: play cards face down, call what suits you, catch the liars — or eat the pile. The world's simplest bluffing game, explained.

On this page

Cheat (I Doubt It in polite American books, something stronger in practice) is card gaming reduced to its most human ingredient: nerve. Deal out the whole deck; each player discards face down while announcing the next rank up, truthfully or not; anyone may challenge, and whoever is wrong (the liar caught, or the accuser of an honest play) takes the entire pile. First hand empty wins, except your final play will always be challenged, so save some truth for the end. Every culture named it after the lie: the Russians play "trust-don't-trust", the Spanish call it mentiroso, the British simply cheat.

Looking for liar’s dice?

This article covers the card game. The version played with dice and cups, Perudo, has its own page with an online dice roller and the odds of each bid: liar’s dice online.

Our full guide (rules, variants and the psychology of good lying) is in Spanish: Reglas del mentiroso. Marked, worn cards spoil the mystery: renew yours from our playing cards collection.
