How it plays

Simple to grasp. Brutal to master.

One rule to learn, a hundred ways to chase a higher score.

=

Match the target

Numbered blocks fall in. Drop each onto a stack until a stack's value hits the TARGET — that stack scores, clears, and the next level begins.

+ − × ÷

Bend the block

Tap the operation buttons to turn the falling block into add, subtract, multiply, or divide before it lands. The math is yours to steer.

±

Nudge & specials

Nudge a block's number by one or two, randomize it, or fire off special blocks stacked above the line for clutch, run-saving plays.

Beat the kill line

Every stack has to stay below the dotted line. Let one grow past it and the run ends — so every drop is a gamble worth taking.

Chase the score

Combos, multipliers, and a level that never stops climbing

Level = your multiplier

Every clear bumps your level — and your level is your points per block. The deeper you go, the more each move is worth.

Bonus badges stack

Land on the right block and multipliers and flat bonuses pile on top of a clear. Big stacks, bigger payouts.
