How to play.

Low is good

Everyone has four cards lying face down in a square in front of them, with values from 0 to 13. Whoever has the fewest points at the end wins.

Two peeks

At the start you look at two of your four cards, whichever you like. Then they lie face down again. Remember them.

Your turn

Draw from the pile or take the top discard. Swap it for one of your cards or discard it. That is how you get rid of high cards.

Several at once

Got two, three or four of a kind? Swap them together for one card, drawn or face up. If you are wrong, they go back, the new card goes on the discard pile and your turn is over.

Action cards

If you discard a drawn 7 to 12 right away, you may use its action.

• 7 and 8, Peek: look at one of your own cards
• 9 and 10, Spy: look at someone else’s card
• 11 and 12, Swap: swap blind with someone

Cabo!

Think you have the lowest total? Say Cabo. Everyone else gets one more turn, then the cards are revealed.

Scoring

The app does the math, by the official rules of the 1st edition (2010). You can change penalty points and the point limit in Settings.

• Whoever has the lowest total in a round scores 0, no matter who called Cabo.
• If several players who did not call Cabo tie for the lowest total, they all score 0. If the Cabo caller ties for the lowest total, only the caller wins.
• Whoever calls Cabo without having the lowest total scores their total plus penalty points, 5 by default.
• Everyone else scores their total.
• With Kamikaze (12, 12, 13, 13) that player scores 0 and everyone else 50.
• Landing exactly on the point limit drops you back to half, every time.
• If anyone goes over 100 points, the game ends and the lowest score wins. On a tie, whoever called Cabo more often wins.

House rules, if you like

Start snap: only at the very start, one card lies face up in the middle. Everyone looks at their two nearest cards. If the same card is among them, snap it quickly: whoever is first gets rid of it. Too slow: the card goes back and nothing else happens. Wrong card: it goes back, plus a penalty card.

Snapping: whenever anyone discards a card and you know where your matching card is, snap it right away, even out of turn. First and correct: it stays down and you have one card fewer. Wrong: it goes back, plus a penalty card.
