Physics and building games for kids
Kids who love building, tinkering and figuring out how things work will find plenty to experiment with here.
In Doodle Bridge (ages 5–7) you draw bridges and ramps with a crayon and gravity does the rest, across 30 levels. Contraption Lab (11–12) is a marble-machine workshop with fans, balloons and gears, plus a sandbox to invent your own. Rocket Lander and Harbor Captain (8–10) are all about gentle, precise control, and Skyline Mayor turns building into planning a whole city.
Every level of Doodle Bridge, Contraption Lab, Rocket Lander and Harbor Captain is proven beatable by an automated solver or autopilot, so there's always a way through.
Games

Questions parents ask
Do these games teach real physics?
They build intuition: gravity, momentum, balance and wind behave consistently, so kids learn by experimenting and seeing what happens.
Is Playzoo free?
Most Playzoo games are completely free, and every game is free to start. An optional family plan ($4.99 a month or $29.99 a year, with a 7-day free trial) unlocks the rest of the bigger games, plus progress sync across devices and family scoreboards.
