The classic matchstick puzzle, rebuilt for your pocket. An equation is laid out in matchsticks, and it is wrong: 4 + 3 = 6. Move a single match to make it true. Easy at first — then a lot less so. WHAT'S INSIDE • 192 hand-validated levels, from gentle warm-ups to two-move and three-number brain-benders • Endless mode: fresh puzzles forever, slowly getting harder • No timers, no pressure — think as long as you like • Three stars for solving without hints. Can you collect all 576? • Daily Challenge: a new puzzle every day, a streak to keep alive and an archive of the last month • A Home Screen and Lock Screen widget with today's puzzle • Game Center leaderboards and achievements • Two-stage hints: first which match to pick up, then where to put it • iPhone and iPad, fully localized in English and Russian HOW TO PLAY Tap a match to pick it up, tap an empty groove to drop it there. Make the equation true and hit Check. The "=" sign is fixed, and on "+" and "−" only the vertical stroke moves — so a plus can become a minus, and back again. FAIR RULES Your answer is never auto-checked: you confirm it yourself with the Check button. Got it wrong? Try again — attempts are unlimited. The game works offline: every level ships with the app and no account is needed. Progress lives on your device and syncs between iPhone and iPad through your iCloud. The game is free and ad-supported: watch a short video for a hint, and every 10 levels you complete earn you one more for free. A calm puzzle for five minutes or a whole evening. Brain exercise without the stress.
