General Questions
What is Liar's Dice?
Liar's Dice is a classic bluffing dice game where each player rolls dice hidden under a cup and makes bids about the total number of a certain face value among all players' dice. Players must decide whether to raise the bid or challenge the previous player's claim. The last player with dice remaining wins. The game combines probability, psychology, and deception.
How many players do you need?
Liar's Dice is best played with 2 to 6 players, though the game works with any number in that range. With more players there are more dice on the table, making probability calculations more interesting and bluffing more rewarding.
What equipment do you need?
Traditionally, each player needs five six-sided dice and an opaque cup to hide them. Online, you don't need any physical equipment at all — just visit the play page and the game handles everything for you.
Is Liar's Dice the same as Dudo?
Yes, Dudo is the original South American name for the game that English speakers commonly call Liar's Dice. The rules are essentially identical. Dudo originated in the Andes region of South America and spread worldwide.
What are other names for Liar's Dice?
The game goes by many names around the world. Common alternatives include Dudo, Perudo, Bluff, Cachito, and Cacho. Despite the different names, the core mechanics — hidden dice, bidding, and challenging — remain consistent.
Rules Questions
What does "wild aces" mean?
In the standard rules, dice showing a one (aces) count as wild — they match whatever face value is being bid on. For example, if someone bids "four threes," then every die showing a three AND every die showing a one counts toward that total. Learn this before bidding math, because most bids include wild ones.
How does bidding work?
Each round, a player makes a bid consisting of a quantity and a face value — for example, "three fives," meaning they claim there are at least three fives among all players' dice combined (including wild aces, unless ones were opened as the first bid). The next player must either raise the bid or challenge it.
What happens when someone opens bidding on ones?
When a player opens the bidding on ones (aces), aces are no longer wild for that entire round. This is sometimes called "breaking aces." Bids on ones require roughly half the quantity of normal bids to be equivalent in difficulty.
What is a palifico round?
A palifico round is a special round triggered when a player is reduced to exactly one die. During a palifico round, aces are not wild and players can only raise the quantity, not change the face value of the current bid.
Strategy Questions
What is a "Spot On" call?
A Spot On call (also called "Calza" in Dudo) is when a player declares that the current bid is exactly right — neither too high nor too low. If correct, the caller gains back one lost die (up to a maximum of five). If wrong, the caller loses a die.
Can you gain dice back?
In the standard Dudo rules, the only way to gain a die back is by making a successful Spot On (Calza) call. If you correctly identify that the current bid is exactly right, you recover one lost die, up to the starting maximum of five.
What happens when you lose all your dice?
When you lose your last die, you are eliminated from the game. The game continues with the remaining players until only one player has dice left — that player is the winner.
When should I challenge?
Challenge (call "Dudo") when you believe the current bid is too high — that there are fewer dice of that value on the table than claimed. As a rule of thumb, each face value appears on roughly one-third of all dice when aces are wild.
How do I calculate probability with wild aces?
With wild aces, each die has a 2-in-6 (one-third) chance of matching any non-ace face value. So the expected count for any bid value across N total dice on the table is roughly N divided by 3. For example, with 15 dice in play, you would expect about 5 of any given value.
Is bluffing important in Liar's Dice?
Absolutely. Bluffing is the heart of the game. While probability gives you a foundation, skilled players use deception to mislead opponents about what they hold. A well-timed bluff can force other players into bad challenges.
