Goal: Capture the entire board by eliminating all orbs of other players.
Turns: Players take turns placing orbs in cells of their color or empty cells.
Critical Mass: Each cell has a limit (2-4 orbs) based on its position. Corner cells have a limit of 2, edge cells have a limit of 3, and all others have a limit of 4.
Chain Reaction: When a cell exceeds its limit, it explodes, distributing orbs to adjacent cells. Explosions don't spread to diagonally adjacent cells. Oh also, explosions propagate!
Capture: When your orbs explode into an opponent's cell, you convert their orbs to your color.
Victory: The last player with orbs on the board wins!
