Perudo (Liars Dice) is a dice game of pushing your luck and communication. Each player rolls five dice under a cup but can only see their own before making a bid on how many dice of a certain number there are in total. It's clever because you can't pass, you either raise the bid or challenge the current player. The result is a game of guesswork, bluffing and luck where additional rules cleverly extend the fun.

Once you have all turned your cup over to roll your dice you take turns to bid on how many dice of a certain number are on the table. Bids can increase either the number of dice or the number they are predicting. So four fives can be followed by four sixes or five fives, but not by four threes.

If the preceding player makes a bid you don't think they can make, based on other bids and the dice you can see under your cub you challenge or "Dudo" them. If there are enough dice to meet their bid you lose one of your dice. If there are not enough dice to meet their bid, they lose a dice. You continue like this, knocking players out when they run out of dice.

There are a couple of twists that extend the challenge. Firstly, you play with one wild dice (can be used as any number). This adds a related rule that rather than raising the bid you can decide to half the current bid and switch to ones. So you can follow a bid of four fives with two ones. Secondly, the first time a player starts with one dice, ones are no longer wild and you can only raise the number of dice you are bidding not the number you are bidding on. You can only follow two fours with three fours.

The result is a finely balanced and competitive game. As the play evolves you have to adjust your bids to match not only what other players are bidding but the dwindling number of dice in play under each cup. Then there is a whole layer of play where you bid something not because you have it but to throw others off the scent. It's a classic game and for good reason.
