Stop calculating. Start surviving.

Remainder™ is a hardcore mental math survival game that turns division into a high-stakes race against time. There are no puzzles to solve—only a rapidly filling Remainder Bin and your own mental agility to keep you alive.

THE CHALLENGE
Numbers fall from the top of the screen. Your goal? Neutralize them before they hit the floor. But there’s a catch: every division that isn't perfect leaves a "mess."

THE MECHANICS
The Dividing Toolkit: Every level, you are assigned 3 unique Divider Numbers. These are your only weapons. Choose wisely.

The Remainder Bin: Any remainder from your division falls into the Bin. If the Bin overflows, the game is over.

Neutralization: The only way to clear the Bin is to make its total sum perfectly divisible by one of your Dividers.

WHY REMAINDER™?
High-Tension Gameplay: This isn't a classroom drill. It’s a tactical survival experience where one wrong move creates a bigger mess.

Hardcore Mental Math: No hints, no color-coding, and no easy outs. You must calculate the divisibility of the Bin Total yourself to survive.

Level Progression: Experience procedurally generated levels that scale in speed and complexity. From simple primes to "Dirty Divisors," every level tests a different part of your brain.

Amazing Calculation Facts: Between runs, unlock fascinating mathematical secrets and shortcuts used by geniuses to calculate at lightning speed.

Offline-First: No internet? No problem. Train your brain anywhere—from the flight to the subway.

Track Your Growth: Monitor your daily high scores and streaks with local charts.
