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.
