PLAYS MATCHSTICK MATHThe classic matchstick puzzle: the equation on the board is false, and you repair it by moving exactly one matchstick. Pick a match up and faint slots show everywhere it could land — even the plus sign's upright stick can move, turning + into −.
If your move leaves the math false — or leaves a digit malformed — the stick snaps back and you lose one of your three lives. The board only judges complete, legal shapes.
Thirty, escalating: single digits first, then two-digit numbers, then puzzles that need two moves (judged only after your last stick lands), and finally both at once with exactly one fix.
Yes — the vertical stick of a plus sign is a movable match, so + can become − and − can become +. Operator flips are the key to many later levels.
