Ask the coach anything

Stuck? The AI coach looks at the position with you. Ask in your own words, like “Why is g8 already covered?”, and it answers the way a person would.

Instead of handing you the move, it points you to the idea, so the next puzzle gets easier.

Coach Dk, a hooded duck, explaining the puzzle in a chat: “Look at h8 — g7 and h7 block every exit except g8.”
