Twenty-One
Four columns, one card at a time, three strikes
Solo, in a pool3 min a roundCardStrategy
Cards come off the deck one at a time and you choose where each one goes. Make twenty-one and the column clears. Go over and it costs you.
How to play
Goal. Clear columns by making exactly twenty-one — without going over.
- Tap one of the four columns to put the current card there.
- Aces count eleven when that fits under twenty-one, and one when it does not.
Scoring
- A column that makes exactly 21 clears for 100.
- A column that holds five cards without going over clears for 150 — and five cards making 21 pays both, 250.
- Each clear straight after another multiplies what it is worth: twice, three times, up to five times.
- A column that goes over twenty-one busts: it clears for nothing, breaks your run, and costs a strike.
Three strikes ends the run, and so does the last card. Get through the whole deck and every second left on the clock adds 4 points. The round lasts three minutes.
How a pool is decided
- Choose a stake — E5, E10 or E20 — and press Play. Your stake is taken then, and you play straight away. The game is played on our servers: they hold the deal and count your score, and your device shows you the game and sends your moves.
- The clock keeps running if you leave. A run you leave part-way ends when its time is up, with the score you had. You can come back to it while it is still running.
- Your score goes into a pool the moment your run ends: the oldest pool for that game and stake that still has room and that you are not already in — or a new one. You see the pool as soon as your score is in it.
- Everyone in a pool plays the identical deal, so the only difference between scores is how each person played it. You are never given a deal you have played before.
- A pool pays the moment it has 5 scores, from 5 different players. The highest score is first and receives 50% of the pot, second 30% and third 10%; the platform keeps 10%. If two scores are equal, whoever finished first ranks higher.
- A pool that does not have its 5 scores 6 hours after its first is cancelled, and every stake in it comes back in full.
- If our side lets you down — the game never opens on your device, or our server restarts in the middle of your run — your stake comes back in full.
- Where a game pays for time left on the clock, it pays only when you finish the game — never when you get stuck, bust or run out of moves.
- Practice is free, up to 10 times a day in each game: your own board, with nothing staked and nothing ranked.
- Winnings land in your Crazy8s wallet, and you can move them to your mobile money whenever you want.
