Place all 8 tiles so every equation balances.
- Drag a tile into a blank, or tap/click a tile and then a blank.
- Every tile must be used exactly once.
- Placing a tile onto an occupied space replaces it; the displaced tile returns home.
- Check becomes available when all 8 blanks are filled.
- After Check, Balanced tells you how many equations are wrong — but not which ones.
- There may be more than one valid solution.
Reset returns the current puzzle to its starting position. I Give Up reveals one known valid solution.
Your time starts only when you tap the blurred tile area. The clock simply records how long you take.
