Chain Reaction Blast is a strategic multiplayer game where players compete to dominate the grid by placing orbs. The objective is to eliminate all other players by triggering chain reactions. When a cell reaches its critical mass, the orbs explode and take over adjacent cells.

Explosion mechanics:
- Corners: Orbs explode after one touch.
- Edges: Orbs explode after two touches.
- Center cells: Orbs explode after three touches.

Before an orb explodes, it rotates, signaling it's ready to burst.
