## What is Marble City?

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.

MADE FOR FAMILIES
No ads. No accounts. No tracking. Plays offline. The app sends nothing to us or to anyone else.
