Red's turn.

This is a 2 players on one computer, turn-based game.
The objective is to convert all atoms to your color.
Each turn you fire one atom of your color into a cell which is empty or occupied by you.
If there are too many atoms in one cell, your atoms explode into the adjoining cells,
converting any atoms already there into your color.
A cell with 4 adjoining cells holds 3 atoms safely. If a fourth one is added, it explodes.
A cell with 3 adjoining cells (a non-corner side) holds 2 atoms safely.
A cell with 2 adjoining cells (a corner) holds 1 atoms safely.
