Dudo (Peruvian Liar's Dice)

Each player shakes their five dice in a cup and looks at their own roll without showing anyone else.

Players take turns making bids about how many dice of a certain value are showing across everyone's hidden dice combined.

Each new bid must raise either the quantity or the face value guessed compared to the previous bid.

Instead of bidding higher, a player may challenge the previous bid by calling 'dudo' (I doubt it).

All dice are revealed; if the actual count meets or beats the bid, the challenger loses a die, otherwise the bidder loses one.

Play continues with fewer dice each round until only one player has dice remaining, winning the game.
