How to Play Cachos
Cachos is Latin America's great dice bluffing game — known as Dudo ("I doubt it") in Peru and Colombia, and as Cachos in Ecuador, where it is a national obsession played everywhere from cantina tables to boardroom team-building sessions. Players hide their dice under cups, make escalating bids on the total count of a face across all cups, and challenge each other with a cry of "dudo!" Pure bluff, probability, and nerve.
What You Need
- 5 dice per player (standard 6-sided dice)
- 1 cup per player to shake and conceal dice
Setting Up
- Each player starts with 5 dice in their cup.
- All players simultaneously shake their cups and set them face-down on the table, secretly looking at their own dice.
- Choose a starting player (youngest, or loser of the previous round).
Making a Bid
A bid consists of two numbers: a quantity and a face value. For example, "three 4s" means: I believe there are at least three dice showing 4, counting all cups at the table combined.
The opening player makes any valid bid. Each subsequent player must either:
- Raise the bid — increase the quantity (any face), or keep the same quantity but increase the face value, or switch to bidding aces (see below). You cannot lower either number.
- Challenge — call "¡Dudo!" (I doubt it) to end the bidding round.
Aces Are Wild
1s (aces) are wild — they count toward any face value bid. So if there are two 4s and one ace under various cups, a bid of "three 4s" is valid.
Bidding aces directly: a player may choose to bid aces instead of a number face. When transitioning from a normal bid to an ace bid, the quantity is halved (rounded up). Example: converting from "six 3s" to an ace bid requires at least "three aces." Converting back from an ace bid to a normal bid: quantity doubles plus one.
Resolving a Challenge
When someone calls "¡Dudo!", all players lift their cups and reveal their dice. Count the relevant face (plus any aces if it was a non-ace bid):
- The bid is correct (actual count ≥ bid quantity): the challenger loses 1 die.
- The bid is wrong (actual count < bid quantity): the bidder loses 1 die.
The losing player removes one of their dice permanently. A player who loses all 5 dice is eliminated. The next round begins with all remaining players re-rolling.
Winning
The last player with at least one die remaining wins. In a two-player endgame, the final die is often the most dramatic moment — each player making do with a single die and perfect information about the probable distribution.
Strategy Tips
- Anchor on your own dice. If you have three 4s yourself, "five 4s" at a 4-player table is statistically likely. Bid with conviction.
- Track what's been bid. If five 3s were bid and challenged successfully (meaning there were at least five 3s), adjust your future bids on 3s accordingly.
- Bid aces to reset. Switching to an ace bid often throws opponents because it forces them to recalculate. It can also bait a premature challenge.
- Know when to challenge early. With many players still in the game, the total dice count is high and bids can escalate wildly. Challenge before it gets to an absurd number.
Cultural Context
Cachos is embedded in Ecuadorian social life at every level. In Quito and Guayaquil, refusing a Cachos challenge at a social gathering carries a mild social stigma — the game belongs to the table like food and drink. National tournaments are held annually, and master players command genuine community respect.
The name cachos refers to the animal horns that the original leather dice cups were made from — a material connection to pre-colonial Andean cattle culture. The game spread across Latin America with Spanish colonization and adapted locally in each country, with regional variations in the ace rules and challenge vocabulary that mark players' origins as surely as an accent.
