Topple - Domino Chain Reaction Builder

Topple is a 3D domino chain-reaction sandbox in your browser. Paint chains of
dominoes on a virtual table, add ramps and marbles, place a starting trigger,
hit Play, and watch the cascade.

Full-featured editor:

• 3 sizes × 8 colors × 3 textures of dominoes
• Ramps and marbles for multi-level chains
• Free orbit camera, snap-to-grid, undo/redo, copy/paste
• Material-aware 3D positional audio
• Save to the in-browser library or export `.topple.json` files

Want to share your creations? This standalone build saves locally only. The
full version at https://topplegame.com adds a free account,
cloud sync, a public gallery, ratings, and shareable replay links. Your
exported `.topple.json` files can be imported there.

Free + name-your-own-price - tips are appreciated but never required.  :)
