It's just you and one cup-rattling AI, and it is quietly learning exactly how you lie.
Liar's Solitaire is a one-on-one dice-bluffing duel. You and the AI each hide five dice under a cup. On your turn you either raise the standing bid, a claim that at least so many dice on the whole table show a chosen face, or call "Liar" to challenge the last bid. When challenged, every die is revealed: if the true count falls short, the bidder loses a die; if it holds, the challenger does. Lose all your dice and you're out.
The mechanism is liar's dice — five dice each under a cup, bids about the whole table, and the choice every turn between raising and calling the previous bid a lie.
What is original is the opponent. Reduced to one AI, a game that normally depends on reading a table of people becomes a duel against something that is reading you: it keeps track of how you bluff and adjusts.
That makes consistency dangerous in a way it never is against strangers. A bluffing pattern that works on humans who meet you once becomes a liability against an opponent that plays you a hundred times, so the game is less about deceiving a stranger than about not having a tell.
Liar's Solitaire reimagines the traditional public-domain dice-bluffing game as a solo campaign against an opponent that genuinely adapts to your habits. It's an original, free browser game with Daily and Practice modes, no download, no sign-up.
