Matchsticks Puzzle

Matchsticks Puzzle is a modern home for a classic brain teaser: move one or two matchsticks to turn a broken equation, shape, or Roman numeral into a correct one. Every puzzle is hand-crafted and hand-verified, with a clean interactive board that works just as smoothly on a phone as on a desktop. The full library contains 525 puzzles across three categories — equations, geometry, and Roman numerals — with difficulty tiers from warm-up easy to genuinely hard. A daily puzzle challenge gives solvers a shared problem each day, and streak tracking rewards consistency without nagging. Global and friends leaderboards rank players by total puzzles solved and by longest active streak. Free accounts sync progress across devices, unlock solution history, and preserve streaks. The puzzle browser makes it easy to drop into exactly the kind of challenge you want — a quick equation fix during a break, or a hard geometry puzzle for a longer sit-down session.
