Simple Chess vs Doctor Chess

Simple Chess is the easiest way for children (and grown-ups) to learn chess. A FRIENDLY COACH Tap a piece and the coach explains how it moves. Dots show where it can go, and a red ring warns you when one of your pieces is in danger. Stuck? Tap Hint and an arrow shows a good move, with a short explanation of why. LEARN EVERY PIECE Short lessons for the pawn, knight, bishop, rook, queen and king, each with a little board to try it out yourself. Special rules like check, castling, promotion and en passant are explained step by step. PLAY TOGETHER OR AGAINST THE ROBOT Play with a friend on one iPhone or iPad, or practice against a friendly robot that makes the occasional mistake. Undo a move whenever you like. Your game is saved automatically. MADE FOR KIDS • Big, clear pieces and four cheerful board colors • Works in light and dark mode • iPhone, iPad and Mac • No ads, no accounts, no data collected
