Learn chess, one dinosaur at a time

Every piece is a dinosaur character, from the Hatchling pawns to the T. rex king. The rules are real chess, so everything children learn works on any board.

Friendly lessons

Each piece has its own short lesson, read aloud if you like. Glowing squares show where to move.

The Dino trail

A step-by-step path: learn a piece, play a little game with it, collect stars, then on to the next stop.

Play the computer

Seven levels to grow through, from the Baby dino who plays almost at random to the T. rex.

Dino games

Languages, maths, science, memory and chess-skill games. No timers and no rush: every round earns stars.

2D or 3D

A flat board, or a 3D one you can turn and zoom. Save a favourite angle for each set of pieces.

Play a friend

Two players on one phone or tablet, or on two devices side by side, paired by a grown-up with a code.

Turn the board in 3D

Drag to spin the board right round, tilt it, pinch to zoom. The royal dinosaurs stand tall on their squares, and you can save a favourite angle for each set of pieces. One tap brings it back.

Prefer it flat? The 2D board is always one tap away.
