Offline Physics Puzzle

Paperball

Draw a line, release the ball, and let physics do the rest.

01

Four pens, four physics

A plain track, a boost that flings the ball the way you drew it, a trampoline, and syrup brakes. Each pen is a different law, not a different colour.

02

Wind bends your plan

Wind zones push the ball off the path you drew for it. Portals fire it out in a direction the level decides. Read the arrows before you commit the ink.

03

55 levels, all proven

Every level is run through an automated solver before it ships. Seven worlds, from the opening Meadow to the Summit Trials — and not one of them is a guess.

04

Nothing leaves the page

No ads, no purchases, no account, no analytics. The release build does not even request internet permission. Your stars live on your device and nowhere else.

The ball waits until you are ready.
