Algodoo

About

Algodoo is a 2D physics sandbox that lets you build and break things using simple tools. Players draw shapes, add materials, and watch how gravity, friction, and collisions behave in real time. The goal is open-ended experimentation, whether you’re making a rolling wheel, a wobbly bridge, or a Rube Goldberg contraption. It runs on Windows and has a straightforward interface that prioritizes quick testing over complex menus. The game’s longevity speaks to its versatility. Teachers use it for physics lessons while hobbyists create animations and puzzles. A 14-year-old release date means a backlog of user-made content online. It’s not flashy but its no-frills approach to physics simulation has kept a steady audience. Those familiar with Phun will recognize the same spirit of playful problem solving.
