Move and place
Drag numbers into new positions and add operators or parentheses. Tap a placed symbol, or drag it outside the sequence and release, to remove it. You can also select a symbol then tap the left or right side of a number. Completed edits are checked automatically; every valid solution is accepted.
Levels and daily challenges
First play starts at level 1 with 4 numbers targeting 24. Six groups have 80 levels each: 480 puzzles. Replay completed levels or choose the first ten unfinished ones. Leaving an ordinary level resets its expression but keeps completion. Three daily puzzles follow the device’s local date and keep separate records.
Offline and feedback
Built-in puzzles need no connection; failed updates do not prevent play. Rotation preserves completed edits. Change language and appearance in Settings. For feedback, include device, OS, app version and reproduction steps. Redact unrelated screenshot details; identity documents are not needed.
