For parents and grown-ups
Rollie only knows how to roll. Your child builds the path.
Tinker Roll: Kids STEM Puzzles is a physics puzzle game for ages 3 to 7. Drag a ramp, a trampoline, a seesaw, or a fan onto the stage, tap Play, and see whether Rollie the robot ball lands in the basket.
Six worlds teach one idea each: slopes, bounce, levers, wind, magnets, and gears. Every level is a small experiment that resets gently when it fails and celebrates when it works. No reading is needed; every instruction is a picture, a motion cue, and a friendly voice.
A quiet place to play. There is no advertising, no chat, no account, and no developer-operated online service. Progress stays on the device. Purchases, restore, sound settings, and outside links sit behind a grown-up arithmetic gate.
Play and learn
Worlds 1 and 2 (16 puzzles) are free. The optional Tinker Roll Family Pass unlocks worlds 3 to 6 (32 more puzzles), the Tinker Lab sandbox for free-form building, and costumes for Rollie. Apple shows the plans, local prices, and any eligible free trial before purchase, and one pass covers your Family Sharing group.
