Liar's Dice

Liar's Dice dates back to 16th-century South America, where Spanish colonists played it with dice carved from bone. The game spread through ports and trading posts. Sailors carried it to Europe. Today it remains one of the most widely played dice games in the world. The concept is brutal in its simplicity. You roll dice in secret. You bid on how many dice show a given face across all players. Each bid must top the last. You either raise or call the previous player a liar. A Wikipedia entry on Liar's Dice traces the game through multiple continents and centuries. Research on bluffing games, including a 2014 study in the Journal of Experimental Psychology, shows that deception games train working memory and probabilistic reasoning. Our version pits you against 1 to 5 AI opponents. Pick your difficulty and start rolling.

1. Choose how many opponents you want: 1 to 5 CPU players. Then pick a difficulty level: Easy, Medium, or Hard.
2. Each player starts with 5 dice. All dice are rolled simultaneously and kept hidden under cups. You can see only your own dice.
3. The first player makes a bid. A bid has two parts: a quantity and a face value. For example, 'three 4s' means you claim at least 3 dice showing a 4 across all players.
4. On your turn, either raise the bid or challenge the previous bid by calling 'Liar!'
5. To raise, increase the quantity, or keep the same quantity and raise the face value. Ones count as wild and match any face.
6. To challenge, click the 'Liar!' button. All dice are revealed. If the actual count matches or exceeds the bid, the challenger loses a die. If the actual count falls short, the bidder loses a die.
7. Players who drop to zero dice are eliminated. The last player with dice remaining wins the game.

• Each player starts with 5 dice, for a maximum of 30 dice in a 6-player game.
• All players roll at the same time. Dice are hidden from opponents.
• A bid consists of a quantity and a face value (1 through 6). Example: 'four 5s' means at least four dice showing a 5.
• Each new bid must be higher than the previous one. Raise the quantity, or keep the quantity and raise the face.
• Ones are wild. A die showing 1 counts as any face value for challenge resolution.
• On your turn you must either make a higher bid or challenge the previous bid. You cannot pass.
• When a challenge is called, all dice are revealed. Count every die matching the bid face plus every die showing 1.
• If the total count is greater than or equal to the bid quantity, the challenger loses one die. Otherwise the bidder loses one die.
• A player with zero dice is eliminated. The last player standing wins.

• Count your matching dice before you bid. If you hold three 5s and the bid is 'five 5s,' you only need two more from all opponents combined. That is a safe raise.
• Use probability to decide when to challenge. With 20 total dice in play, each face has an expected count of about 3.3 (including wild ones). If someone bids 'ten 4s,' the odds are against them. Challenge.
• Bluff selectively. Bidding higher than your dice support can pressure opponents into bad challenges. But do not overdo it. Skilled players will catch on and call you out.
• Track eliminated players and lost dice. Fewer total dice means bids should shrink. A bid of 'eight 3s' is reasonable with 25 dice in play but reckless with 10.
• Ones are wild, so bids on 1s are harder to challenge. Every die showing 1 also counts toward any face bid. Factor that into your probability math before you call 'Liar!'

• Common Hand: The most popular variant. All players roll one set of dice and bid on the total across everyone. Ones are wild. This is the version played on our site.
• Perudo: A South American variant where players lose dice on wrong challenges and the last player with dice wins. Bids use palifico rounds where ones are not wild.
• Backgammon: A different dice-based game where you roll and move checkers, combining luck with positional strategy.
• Yahtzee: A dice rolling game where you score combinations across 13 rounds. No bluffing, just probability and risk management.

• Every round is a mind game. You read opponents and guess their dice.
• Games are short. A full match takes 5 to 15 minutes.
• The bluffing layer adds tension that pure luck games lack.
• Rules are simple enough for children but the strategy runs deep.
• It works with any number of players, from 2 to 6, and scales naturally.
