## What is Rubber #25?

Slide a pink eraser across a school notebook and rub out the doodle hiding under the grid. Absorb pencil numbers to refuel, plan your route, and clear the whole sheet before the eraser crumbles.

HOW IT WORKS

Each level is one notebook sheet: a 5x5 grid drawn over a hand-made doodle. Swipe (or tap the keypad) and the eraser slides until something stops it, erasing every cell it crosses and spending 1 charge per cell. Hit zero mid-slide and the eraser crumbles - plan before you move.

NUMBERS ARE FUEL AND WALLS

Pencil numbers wait on the sheet. A number heavier than your current charge is a wall - your slide stops in front of it. A number you can carry gets absorbed: it joins your charge and ends the move. The header shows which numbers come next, so you can think ahead.

EVERY LEVEL IS FAIR

No luck, no dead deals. Every sheet is dealt from its own seed and checked by a solver before you ever see it, so a winning line always exists. Retry a level and you get exactly the same deal - every sheet is a puzzle you can learn and master, not a dice roll.

TWO WAYS TO PLAY

Classic mode refills the sheet after every move, drawing numbers from a fair bag so heavy streaks cannot happen. Static sheets (a settings toggle) lays every number out before your first slide - no spawns during play, just one tight route to find.

MADE FOR QUIET MOMENTS

- 99 hand-drawn doodles to rub out, one per sheet - and the levels keep going after that
- Plays offline, no internet needed
- Paper theme by day, night-notebook theme after dark
- Path score, best run, and lifetime stats
- No energy bars, no timers, no move limits

FREE TO PLAY

Rubber #25 is free with a small banner ad. A single optional purchase removes ads forever - nothing else is sold.

Sheet 1 is waiting. Pick up the eraser.
