Liar's Dice Rules: How to Play, Bid, and Bluff

Setup

Five dice per player and a cup each. Two players works, five or six is where the game comes alive, and beyond eight the bidding gets slow.

Everyone rolls their five dice under the cup, lifts the cup just enough to peek, and keeps the result private. You know your own five. You know nothing about anyone else’s.

That asymmetry is the whole game. You’re not guessing what’s under your own cup. You’re reasoning about what’s probably under everyone else’s, and about who is confident enough to raise.

The bid

Bids describe the whole table, not your own hand.

A bid is a quantity plus a face. “Four 3s” claims there are at least four dice showing 3 among all the cups in play, including your own.

Play moves clockwise. Each player either raises the bid or calls the previous bidder a liar.

Raising means one of two things. Increase the quantity, keeping the face or changing it: “four 3s” can become “five 2s” or “five 6s”. Or keep the quantity and increase the face: “four 3s” can become “four 5s”. You can’t go down in either dimension.

Ones are wild

In the standard game, 1s count as any face. So if you’re holding 1, 1, 4, 6, 6, you can count that as four 6s, or three 4s, or two 1s if 1s are the named face.

Wild 1s inflate every number on the table, which is why bids climb faster than beginners expect. A table of five players has twenty-five dice in play. Any given die shows a specific face 16.67% of the time, but shows either that face or a wild 1 33.33% of the time. Bids of eight or nine on a five-player table are routine.

Note that when 1s are the named face, they aren’t wild in addition, they’re just 1s.

Calling liar

When you don’t believe the bid, say so. Then every cup comes up.

Count the dice matching the bid’s face, including wild 1s.

If there are at least as many as the bid claimed, the bid was good and the caller loses one die. If there are fewer, the bidder was lying or wrong, and the bidder loses one die.

Losing a die is permanent. You roll four next round, then three, and so on. Drop to zero and you’re out. Play continues until one person has dice left.

Perudo’s rules add a third option, called calza or spot on. Instead of doubting, you declare the bid exactly right, not one more and not one less. Get it right and you win a die back, up to your starting five. Get it wrong and you lose one like any failed call. It’s worth adding once everyone knows the base game.

Palifico

Perudo, the boxed commercial version of liar’s dice, adds a rule that fires when a player drops to a single die.

That round is a Palifico round, and two things change.

Ones are not wild. A 1 counts as a 1 and nothing else.

The player down to one die opens the bidding, and whatever face they name is locked for the round. Everyone after them can only raise the quantity, never the face.

Palifico is a lifeline. Everyone else has spent the game doing mental arithmetic that assumes wild 1s, and Palifico pulls that assumption out from under them. Players who are used to the standard count regularly overbid and hand the single-die player a free elimination.

Some tables only apply Palifico the first time a given player hits one die. Others apply it every time. Sort it out before it comes up.

Other variants worth knowing

Common hand is the one to watch out for, because the naming catches people out. Wikipedia splits liar’s dice into two families. Everything above is the individual hand game, sometimes called single hand: each player has their own dice, and bids cover every hand on the table. In the common hand game there’s just one set of dice passed from player to player, and the claims are poker hands rather than counts, so you declare a pair or a full house and the next player either re-rolls to beat it or challenges. It plays best head to head. Different game, same name, so check which one people mean.

Dudo is the older South American ancestor of Perudo, and the two names get used interchangeably. Wikipedia treats Dudo as the parent game. If someone invites you to play Dudo, expect Perudo rules with regional tweaks.

Pirate’s Dice is the version most people met through Pirates of the Caribbean, and it’s standard liar’s dice with wild 1s.

How to actually be good at this

Count your own dice first, then estimate. With five players and five dice each, twenty-five dice are in play. Any single die shows a given face 16.67% of the time, and because 1s are wild, the share that counts toward a bid on 5s is really 33.33%. Do that math once, then adjust for what you’re holding.

Bid what you have. The safest raise is one you can partly back with your own cup. If you’re holding three 4s, bidding “six 4s” needs only three more from twenty dice you can’t see, which is a comfortable ask.

Watch the reluctant raisers. A player who raises the quantity by exactly one, every time, is usually holding nothing and stalling. A player who jumps the quantity by three is either very strong or very committed to the lie.

Call earlier than feels comfortable. New players almost never call. They raise on hands that don’t support it because calling feels rude. The bids drift upward until the numbers are absurd and the person who finally calls has been handed a free win.

If you want the underlying arithmetic, the dice probability guide covers how many outcomes multiple dice produce and why counts cluster where they do. For other bluffing-adjacent dice games, the dice games overview has the list. And the dice roller handles five dice at a time if you’re a cup short.

FAQ

How many dice does each player get in liar’s dice?

Five dice per player, rolled under a cup and kept hidden. Players lose one die each time they lose a challenge, so hand sizes shrink as the game goes on. A player with zero dice is eliminated. A six-player game starts with thirty dice on the table.

Are ones wild in liar’s dice?

Yes in the standard game and in Perudo. A 1 counts as whatever face the current bid names, so a hand of 1, 1, 5, 5, 2 counts as four 5s. The exception is a Palifico round, when a player is down to one die: 1s count only as 1s for that round.

What happens when you call someone a liar?

Everyone lifts their cup and the dice matching the bid’s face are counted, wild 1s included. If the count meets or beats the bid, the challenger loses a die. If it falls short, the bidder loses a die. Play then continues with the player who lost the die opening the next round.

What is Palifico in liar’s dice?

A special round triggered when a player drops to one die. Ones stop being wild, the single-die player bids first, and the face they name is locked, so everyone after them can only raise the quantity. It’s a comeback mechanic that punishes opponents still counting on wild ones.

Can you raise the face value without raising the quantity?

Yes. From “four 3s” you can bid “four 5s” without changing the quantity, because the face went up. You can also raise the quantity and keep or lower the face, so “five 2s” is legal after “four 3s”. What you can’t do is lower both, or repeat the bid unchanged.

How do you win at liar’s dice?

By being the last player with at least one die. Everyone else has to be eliminated, which happens one lost challenge at a time. Since losing a die makes you weaker in every following round, the player who avoids early bad calls usually ends up with a real edge late.
