Three check chess changes one thing and leaves everything else alone: check the enemy king three times and you win on the spot. Ordinary checkmate still ends the game as well, so there are two ways home — but almost every game is decided by the counter.
The counter turns check into currency
In ordinary chess a check that achieves nothing is a beginner's move. Here it is a third of a win, and the whole balance of the game shifts: a knight that can deliver an annoying check from a far corner is suddenly worth keeping, and the king's shelter matters more than material. A double check counts as one, not two.
Why we recommend it as the first variant to try
It teaches exactly the thing beginners are weakest at — seeing checks — and it rewards them for looking. A child who plays a few games of this starts spotting forcing moves in ordinary chess too, because they have spent an hour searching the board for every possible check instead of one.
What has not changed
Everything else. Castling, en passant, promotion, stalemate, the way each piece moves: all standard. If a child knows how to play chess, they know how to play this after one sentence of explanation.
More chess to try
Every one of these is the same board and the same pieces with one rule changed, and each has its own page: Chess960, Duck Chess, King of the Hill, Three-Check, Crazyhouse, Antichess, Atomic Chess and Fog of War. If you would rather start with the ordinary rules, our chess for kids teaches them from the first move.
How to play
Everything is standard chess — moves, castling, en passant, promotion — with one addition: give check to the enemy king three times and you win immediately. Ordinary checkmate still ends the game too. A double check counts as one, and the counter beside the board shows how many checks each side has landed. The difference from ordinary chess is that a check is no longer just a threat — it is a third of a win.
Drag a piece or tap it and tap where it should go — legal squares light up, and a move the rules forbid simply will not happen. The computer takes the other side, and it plays this variant rather than ordinary chess: its evaluation is rewritten for the rule that changed. You can also play a person instead: press the two-player button, share the room code, and the other browser joins the same game — this variant included.
What your child learns
Finding forcing moves. Because checks are worth something concrete, a child scans the whole board for them every single turn — and scanning for checks is the exact habit that later turns into finding tactics, forks and mating nets in ordinary chess. It also teaches the other half of the lesson: your own king's safety is not an abstract virtue, it is a resource you can spend down to nothing in three careless moves.
The science behind the games
Every Dad4Kids game is built on one simple truth: children want to play, not study — so we turn learning into a game worth replaying. The method draws on peer-reviewed research in game-based learning, motivation, and how memory works.

FAQ
Is there a three-check rule in normal chess?
No. In standard chess you can check as often as you like with no reward, and only repetition of position or the fifty-move rule end things by count. Three-check is a separate variant that makes those checks worth something.
Do three checks in a row have to be consecutive?
No. They accumulate over the whole game in any order, and the counter beside the board keeps track for both sides.
Does a double check count as two?
No, it counts as one. What is counted is the number of times the opponent has been placed in check, not the number of pieces doing it.
Can you still win by checkmate?
Yes. Checkmate ends the game exactly as it always does — and note that the mating move is itself a check, so a mate also ticks the counter up.
Does it work on a tablet?
Yes. Tap a piece, then tap the square you want — the same as dragging with a mouse. The board turns to fit the screen in both orientations.
