Stone spheres crawl along the temple track toward the skull pit. If a single sphere reaches it, you lose a life. Clear every sphere to survive.
- Aim with the mouse — the stone frog follows your cursor.
- Left click / tap to spit the loaded sphere.
- Right click, Space, or tap the frog to swap the loaded and reserve spheres.
- Land 3 or more of a colour together and they burst.
- Bursts leave gaps. When the trailing chain slams shut on a matching colour it detonates again — that's a chain reaction, and it multiplies your score.
- Firing into a gap between two chains scores a Gap Bonus.
