A wrong equation made of matchsticks. Move exactly one match and make it true. 400 puzzles, no ads, no account, works offline. A wrong equation, made of matchsticks. Move exactly one match and make it true. That is the whole game. No timer, no lives, no pressure — just you and a small, stubborn puzzle. HOW TO PLAY - Drag a matchstick onto an empty outline, or tap the match and then tap the outline - You may move one match, and one only - Digits are seven-segment shapes, so a 6 becomes an 8 with a single stick - The + and − signs are made of matches too, and the hardest puzzles hide right there 400 PUZZLES, RATED HONESTLY Every puzzle is built from a true equation and checked by a solver before it appears, so a solution always exists. Difficulty is measured rather than guessed: how many solutions there are, whether the operator has to change, and whether the match must travel between digits. Four levels, from a gentle start to genuinely hard. FOUND A DIFFERENT ANSWER? IT COUNTS Fiammo checks your move with a solver instead of a fixed answer key. If your solution is valid, the puzzle accepts it, even when it is not the one we had in mind. STUCK A hint first shows which match to move, then where it goes. You earn a hint for every four puzzles you solve. BUILT TO BE QUIET No ads. No account. No sign-up. No tracking. Nothing is sent anywhere: the whole game runs on your device and works in aeroplane mode. Progress can optionally sync through your own private iCloud, which we cannot read.
