Chess coordinates, made into games
Know every square by name.
e4e5Nf3 turns the chessboard's coordinates into quick games. Name squares, find them, call their colour, spot mates and drill your openings. And every move you make, you write down the official way: e4, e5, Nf3.

Checkmate.
Five games
One skill, five ways to practise it.
Every game drills coordinates from a different angle, so they stick whether you're reading them, finding them or typing them.
- Name the Square
- A square lights up and you type its name. Play it from White's side, from Black's, or with the board flipping between them.
- Find the Square
- A coordinate appears and you click that square. The board has no labels, so you have to know where d6 lives.
- Light or Dark?
- Is g5 light or dark? Answer without looking at a board. There's a neat trick, and the game teaches it to you.
- Mate in One
- Find the checkmate and write it down, like Qxf7#. Classic mating patterns, from both sides of the board.
- Openings
- The game plays one side of an opening and you answer from memory. New lines are shown with arrows first.
The one rule
Moves are written, never dragged.
No dragging and no clicking. When there's a move to make, you type it the way it's written on a scoresheet, in official algebraic notation. And the board never shows its coordinates, so you learn to read it yourself.
- Nf3 brings a knight to f3; e4 is a pawn move.
- Capture and check marks are optional: Qf7 and Qxf7# both count.
- Castle with 0-0 or 0-0-0, and promote with e8Q.
- Typos shake instead of costing you the move.
White to move. Promote and mate.
Every keystroke is checked against the position, so you can only ever write a legal move.
Progress
From Pawn to Grandmaster.
Every round earns experience. Keep a daily streak going, beat your best scores, and watch squares turn from strangers into old friends.
- Levels
- Seven ranks, each with its own piece. Rounds earn experience; faster answers earn more.
- Daily streaks
- Play a round a day to keep the fire burning. Miss a day and it starts again.
- Square map
- See which squares you know cold and which ones still make you squint, from each side.
- Best scores
- A best score for every game, side and round length, so there's always one to beat.
