Ready, set… fuse!
Your 60-second clock starts when you select your first number tile. Select a tile, choose + − × ÷ from the strip beneath the board, then select another touching tile. Keep building until you reach the target, then press FUSE. There is no required tile count—you can use any or all 25 tiles once.
6×5−6=24
- Connect to any selected tile, including diagonals. Gold tiles are selected; the cyan marker shows your current tile. Dim tiles do not border your selection.
- Calculations run in selection order, step by step, as the parentheses show. Division must be exact. Tap a selected tile to remove it (and any later tiles left disconnected); UNDO removes your last choice.
- Correct tiles burst. New tiles drop from above.
- Incorrect submissions lock input for 1.5 seconds. The clock keeps ticking!
- Fast solves build a multiplier. Three-tile fuses add 0.75 seconds; four or more add 2 seconds.
- Earn 300 points per tile, plus 100 for +, 150 for −, 250 for ×, and 350 for ÷. Length bonus: 75 × (tiles beyond two)². Each extra distinct operator adds 200. Your combo multiplies it all.
- Keyboard: Tab and Enter to select; +, − (minus key), * and / choose operators. Escape undoes.
Daily: one ranked attempt per Google account or temporary guest session per UTC day. Guests enter a public nickname; their scores appear with a Guest label. Guest identity is not a saved account and ends when the session expires. Google keeps your nickname and daily results tied to your account. Everyone starts with the same board and deterministic tile supply; your choices shape later boards and targets. The daily timer continues if you refresh or leave. Practice is random, unlimited, and never ranked.
