ChessIQ

Raise your chess IQ. ChessIQ is a chess trainer that teaches you to think like a stronger player: solve chess puzzles, learn chess from your very first move, and play chess offline against a chess AI with 6 levels. No ads, no sign-in, no internet needed.

♞ CHECKMATE PUZZLES THAT TRAIN YOUR EYE
Sharpen your vision with a daily chess puzzle and hand-picked checkmate puzzles: the back-rank mate, the two-rook ladder, the queen mate and more. Find the winning move, ask for a hint or the solution when you need it, and learn the mating patterns every strong player knows by heart.

♛ LEARN CHESS, STEP BY STEP
New to the game? The course starts at the beginning and walks you through 21 chapters and 58 chess lessons: the board and pieces, how each piece moves, check and checkmate, castling, en passant and promotion, then real chess strategy — tactics, opening principles and how to plan. Every lesson is played on a live board with legal moves highlighted, and each chapter ends with a short test that shows you the right idea when you miss it.

♚ PLAY CHESS VS COMPUTER — OFFLINE
Challenge a chess engine that runs right on your phone. Pick Beginner, Easy, Intermediate, Advanced, Expert or Master, or set an exact Elo rating from 600 to 2600 to find your level. Play white, black or random, take a hint when you are stuck and take back a move to learn from a mistake. It answers instantly, even in airplane mode.

♜ CHESS OPENINGS EXPLORER
Study 42 named chess openings — the Italian Game, Ruy López, Queen's Gambit, Sicilian Defense, French Defense and more — and play through every line on the board to understand the plan behind the moves.

♝ TWO PLAYER CHESS
Sit across from a friend and play on one device, with a move list, captured pieces and a flip-board button.
