Marble City: Build & Roll
Build marble runs, grow a city
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Snap ramps, planks and bouncers onto the grid, drop the marble and watch it roll. Every level you solve raises a new building on your street.
Marble City is a building game for kids about 6 to 10. Each level gives you a few parts: ramps, planks, bouncers, boosters and launchers. Snap them onto the grid, drop the marble, and watch it roll to the bucket. Got it? A new building rises on your city street.
There is no timer and no wrong way to try. Move a part, run it again, and see what changes. Hints are there when you want one, and a grown-up can turn them off.
WHAT YOU CAN DO
- Solve hand-made levels in Rooftops and Waterworks
- Collect sparkles and earn new marbles
- Build anything you like in the Workshop and save it on your shelf
FREE TO PLAY
Rooftops and the Workshop are free. One purchase, made by a grown-up behind a grown-up question, unlocks Waterworks and every later district and twelve saved builds, and lets you earn all the other marbles with sparkles.
