Cuarenta is played with the baraja española, a deck of 40 cards. It has four palos (suits) — oros, copas, espadas and bastos — and each palo runs 1 through 7, then three face cards: the sota (10), the caballo (11) and the rey (12). That is the whole deck, not a bigger one with cards taken out. The sequence that matters for captures runs 1, 2, 3, 4, 5, 6, 7, sota, caballo, rey. Cards are dealt five at a time.
There are three ways. Matching: play a card sharing a rank with one on the table and take it. Addition: any card from 1 to 7 captures a combination of table cards whose values sum to it. Sequence: after a match or an addition, keep taking the next card up in sequence order while it is on the table. Capturing alone scores no points (only caída, limpia, ronda and cartón score), but captured cards count toward cartón at the end of the round.
A caída is worth +2 points. If an opponent plays a card and it is still sitting alone on the table, matching it immediately is a caída. It does not count if that card was left over from an earlier deal: only a card played that instant, by someone else, qualifies.
A limpia is any capture that empties the table entirely, worth +2 points — whether it comes from a match, a sum, or a sequence chain. A caída and a limpia on the same play stack, for +4 in total. The exception is “38 que no juega”, where the limpia is voided and only the caída's +2 counts.
Being dealt three cards of the same rank is a ronda, worth +2 points. Being dealt all four is a doble ronda: it wins the game instantly, without another card being played.
Once all 40 cards have been played, each side counts its captured pile. Holding more than 20 cards scores 6 points, plus 1 per card past 20, rounded up to the next even number: 21 or 22 cards is +8, and 23 or 24 is +10. If the count is tied, the side about to deal next takes “dos por dar”, +2. If neither side reaches 20 because cards were left uncaptured, whoever holds more scores +2. Cartón scores nothing at all for a side already at 30 points or more: a game cannot be won on cartón alone.
Landing on exactly 38 points closes the easy roads: limpias, rondas and cartón stop scoring for you. The only way to reach 40 from 38 is a caída — matching the exact card your opponent just played. And even if that caída also clears the whole table, it is worth its usual +2 rather than the +4 of a caída-and-limpia combo: the limpia stays voided.
Cuarenta is the national card game of Ecuador, played by 2 to 4 people with the 40-card baraja española. It was born and took root in the sierra, above all in Quito, and is played across the country. The name works twice over: the 40 cards it is played with, and the 40 points you have to reach to win.
