Aritmetris

Aritmetris is a mental-math arcade puzzler where the right calculations clear the board.

Pieces drop as number + operator + number. Watch the current target, connect numbers and operators, and build the correct calculation before the board fills up.

Short sessions, quick decisions, and just enough arithmetic pressure to make your brain warm up.

How to play

• Every target asks for a specific result.
• Match numbers and operators vertically, horizontally, or diagonally.
• Every time you hit a target, a new one appears.
• You may already have calculations waiting for the next target when a new piece lands.
• Build combos and long calculation chains to clear more of the board.

Game modes

Classic

Start with simple additions, small numbers, and easy targets. As you move up through the levels, more operations, bigger numbers, and tougher decisions start to appear.

Sprint

For players who want the game to escalate faster. Bigger numbers arrive earlier and the operations become trickier sooner. Once Classic is under control, Sprint is the next step.
