MatchPuzzleApp

Move a single matchstick and turn a wrong equation into a right one.
You know this puzzle. Here it never runs out, and every one has exactly one answer.

5 + 7 = 2

This is wrong. Move one matchstick and it becomes true. Which one?


FEATURES

- New puzzles every time
Nothing is pre-written. A fresh equation is built each time you play.

- Exactly one answer
Before a puzzle reaches you, every possible move is checked. Only puzzles with a single correct result are used, so you will never find a second answer the app refuses to accept.

- Solve with your fingers
Tap a match to lift it, tap an empty slot to drop it. Pick it up again as often as you like, or start over.

- Today's Match
The daily puzzle is set by the date, so everyone in the world gets the same one. Solved days stay on a calendar and your streak builds.

- The Changes book
Every way a figure changed in a puzzle you solved (6 to 0, + to −) is collected. Changes you haven't met yet turn up more often.

- Four levels
Starter (one stick, single digits), Normal (one stick, up to two digits), Hard (two sticks, up to two digits), Oni (two sticks, one figure changes by two).

- No language needed
The screen holds nothing but an equation. A brain teaser for any age.

- Your stats
Puzzles solved, average time, no-hint solves and your daily streak.
