21 Match is a card board you clear by arithmetic. Every group you take has to be connected and has to add up to exactly 21 — face cards count 10, aces count 11 — and every group you take, or bust, costs one of your moves. New cards drop in from the top, so the board you finish a level on is never the board you started with.
21 Match takes the one number everybody already knows from blackjack and turns it into a board puzzle. There is no dealer, no betting and no luck of the draw to blame — the whole board is in front of you, and the only question is which connected handful of it adds to exactly twenty-one.
The tension comes from the move counter. Clearing a group costs a move and so does busting, so a careless tap is worth exactly as much as a good one, and a level with four moves left is a level where you count twice. Cards keep falling in from the top, which means a board is never solved in advance — the group you were saving may not survive the group you just took.
Levels widen from a four-card square to a full board, moves get tighter, and around level ten the goal stops being ‘make five 21s’ and starts asking for hearts, or spades, or three suits at once. Lives are shared across the campaign and refill on their own, so a bad run costs time rather than progress.
How to play 21 Match
Clear the level's goal before the moves run out:
- Tap or drag across cards to select them; the running sum shows above the board.
- Keep the selection connected — a card has to touch what you already picked, directly or across empty gaps.
- Land on exactly 21 and the group disappears. That costs one move.
- Go over 21 and it is a bust: the selection resets and the move is spent anyway.
- Empty spots refill with new cards falling from the top, so the board keeps changing under you.
- Meet the target shown at the top — a number of 21s, or a number of cards of a given suit — before the moves run out.
- Stuck? The hint button lights up one group that works — you carry three, and clearing a new Adventure level earns one back. The daily modes run with no hints at all.
Game modes
| Mode | What changes | Who it's for |
|---|---|---|
| Adventure | 400 levels that widen the board, cut the moves and switch the goal from counting 21s to collecting suits. | The main line — play it in short sittings, five lives deep, and the levels come back if you lose one. |
| Daily Survival | Five levels in a row from the day's seed, three lives for the whole run, one run per day. | Players who want one sharp test a day rather than steady progress. |
| Daily Streak | A single level picked near your current progress, the same for you every time that day. Clear it and the day counter goes up; miss a day and it resets. | Anyone who likes a reason to come back tomorrow. |
Tips for 21 Match
- Count down from 21, not up from zero: look for the 10 or the face card first and ask what pairs with it.
- An ace is 11, which makes A-10 a two-card clear — the cheapest group in the game and the easiest to miss.
- Busting costs the same move as clearing, so check the sum before the last tap rather than after.
- On suit goals, a group of 21 that happens to be all one suit does double duty; hunt for those before taking any group.
- Cards fall from the top, so clearing low on the board reshuffles more of it than clearing along the top row.
- Empty gaps conduct: two cards on opposite sides of a hole are still connected, which opens groups that look impossible.

About this game
- Controls
- Tap cards one by one, or drag across them, to build a group. The group has to stay connected — each card touching the selection directly or across the empty gaps. Hit exactly 21 and the group clears; tap a selected card again to drop it, or tap the board to start over.

Frequently asked questions
Is 21 Match free to play?
Yes. It runs in your browser on crokocat with no download and no sign-up, on desktop or phone.
Is this blackjack?
No. It borrows the number 21 and the card values — face cards are 10, aces are 11 — and nothing else. There is no dealer, no betting and no hidden cards: it is a puzzle where the whole board is visible and you choose which group to take.
What does connected mean?
Every card in a group has to touch the rest of the selection, either side by side or across the empty gaps left by cards you already cleared. Diagonals do not count, but a hole in the board does not break the chain.
What happens if I go over 21?
The group busts: the selection clears and the move is spent. It costs exactly what a successful group costs, which is what makes the last few moves of a level worth slowing down for.
What are the hearts for?
They are lives, five of them, shared across Adventure. Failing a level costs one, and they refill on their own over time. You can also get one straight away by watching an ad or by sending a friend your link — when they start playing, you get the heart.
Why do I have to wait after a level?
From level sixteen on, clearing a new level starts a short timer before the next one opens — three minutes at first, ten later on. Levels you have already cleared stay open. You get one free skip to spend whenever you like, and a friend arriving through your link lifts the wall immediately.
Does my progress carry between devices?
Level, stars, streak and the rest are saved in your browser. Sign in on crokocat and they travel with your account instead.
