Step 01 · Coordinates

Know every square by name.

Six drills that turn the board into a map. Name the Square and Find the Square are free at every level, and level 1 of the other four is open to everyone. Play them here, no account needed.

Answer by voice in Chrome, Edge or Safari, or tap. Nothing is recorded.

  1. Name the Square

    A square lights up. Say or tap its name.

    The classic drill. A square is highlighted and you answer with its coordinate by voice or by tapping. Levels expand from a single quadrant to the full board with the board flipped.

  2. Find the Square

    Hear a coordinate. Tap the square.

    Light or dark? Answer without looking.
