Number Blast

About the Game

Number Blast is an original arcade maths game with 50 handcrafted levels. A neon grid is packed with number tiles and operator tiles; drag a path through neighbouring tiles — a number, a sign, a number — that makes the target, and release to blast it. Blasted tiles explode in light, the tiles above fall into place and new ones drop in. Bomb tiles used in an equation explode their neighbours, and any bomb caught in the blast goes off too, so one good equation can set off a whole chain reaction; stone blocks crack when something next to them blasts. Most levels run against the clock, and a wrong answer costs three seconds. Five chapters cover adding and subtracting, the times tables and division, number sequences and rule targets such as "any even number" or "a multiple of 6", fractions and percentages like "25% of 8", and finally primes and five-tile chains. All arithmetic is exact — fractions are worked out as fractions, never rounded — and every level is played through by a bot during development to check that it can be completed.

How to Play

The target is shown at the top. Press on a number tile and drag through neighbouring tiles — up, down, sideways or diagonally — alternating number, sign, number. The running total appears above the board as you drag; release when it matches the target and the tiles blast. Equations are worked out from left to right, so 2 + 3 × 4 is 20. On long-chain levels you can drag five tiles: number, sign, number, sign, number. Some targets are rules instead of numbers: any even or odd number, any prime, any square number, a multiple of a number, or anything above or below a value. Glowing bomb tiles explode the tiles around them when you use them in an equation, and a bomb caught in an explosion goes off too. Stone blocks can't be used, but they crack when a tile next to them blasts. On timed levels a wrong answer costs three seconds. If no equation on the board can make the target, the board remixes itself for free. Clear every target to finish; faster runs with bigger chains score more and earn up to three stars.

Gameplay Tips

• •Look for the target's building blocks first: 24 is 4 × 6, 3 × 8 or 20 + 4.
• •Watch the running total while you drag — back up a tile by dragging back over it.
• •Use bombs early: chain reactions clear space and score big.
• •Equations go left to right, so 3 + 2 × 4 is 20, not 11.
• •For fractions, think in quarters, thirds or sixths before you drag.
