About this game

One app. Six smart challenges. A calmer way to train your focus.

MindGrid brings Chess, Sudoku, Nonogram, Kakuro, Binairo and Lights Out together in one polished collection of offline brain games. Play for a few minutes or settle into a deeper strategy session—no account is required, and every game works without an internet connection.

PLAY CHESS OFFLINE

Challenge the built-in chess AI or share the board in pass-and-play mode. The offline opponent varies its choices for a more natural match. Legal move highlighting, visible AI moves, check and checkmate detection, castling, en passant, promotion, hints and undo keep every game clear while preserving real chess rules.

SUDOKU FOR EVERY SKILL

Choose quick 4×4, 6×6, classic 9×9 or diagonal Sudoku. Use notes, related-cell highlighting, mistake feedback, undo and strategy hints. Every generated puzzle is checked for one solution, and unfinished games can be resumed later.

FOUR MORE LOGIC GAMES

• Nonogram — follow row and column clues to reveal a hidden picture
• Kakuro — complete number-crossword sums with unique digits
• Binairo — balance zeros and ones without creating triples
• Lights Out — find the sequence that turns every light off
