Rub out 99 hand-drawn doodles with a pink eraser. Absorb pencil numbers to stay charged - every sheet is a fair, learnable puzzle with no luck and no dead ends.
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.
