About this game

MathMania Trinity — the equation puzzle.

Three numbers. One equation. Tap A, then B, then the result C — and if they make a true equation, all three vanish. Clear the board!

HOW TO PLAY
- Tap three numbers in order: A, B and the result C.
- The game reads A ∘ B = C and tries every operation for you — no operation buttons:
3 → 5 → 8 is 3 + 5 = 8
8 → 5 → 3 is 8 − 5 = 3
4 → 6 → 24 is 4 × 6 = 24
24 → 6 → 4 is 24 ÷ 6 = 4
2 → 3 → 8 is 2³ = 8
5 → 12 → 13 is 5² + 12² = 13² (a Pythagorean triple!)
- The last tap is always the result.
- A must "see" B, and B must "see" C: same row, column or diagonal with only empty cells between them, or the end of one row and the start of the next.
- 0 and 1 count too (7 × 0 = 0, 7 ÷ 1 = 7, 7⁰ = 1) — just never divide by zero.
- Rows and columns that become empty disappear, and the board shrinks.

SCORING
- Addition and subtraction: 1 point
- Multiplication and division: 4 points
- Powers: 10 points
- Pythagorean triples: 20 points
- Trivial triples (with 0 or 1, or the classic 3-4-5): 1 point
- Bonuses: reach across the board for distance points, and play fast for speed points.
- Clear the whole board with no eliminations for a big bonus!

STUCK?
When no equation is left, the game analyzes the numbers for you. First it removes the ones that can't make an equation with any other number. If you're still stuck, it removes the ones left out of the best possible set of equations. Each removed piece costs points — but the board shrinks, and a new equation may open up!

HINTS
Hints always point to the most "cornered" number. But careful: the hinted equation scores nothing, and if you ignore it, your next 10 equations score nothing either.
