Carrom
The classic 4-player board game, rebuilt for the web. Flick the striker, pot your coins, and out-angle a friend (local 1v1/2v2, same device) or a built-in AI opponent — no download, no login. Version 1.0.1 adds a "Feel the Physics" mode where you can adjust real-world parameters like friction, gravity, restitution, and coin/striker mass and watch the board respond live.
The C++/Windows download is the native SFML desktop build (Windows 10/11, 64-bit, no installer) — same rules and physics as the browser version, plus room-code online multiplayer and a friends list.
