Filler
Rules
You and a bot share one hexagonal board. Each of you owns a territory, starting as a single corner cell. On your turn, pick a new color: your whole territory repaints and absorbs any neighboring cells of that color — and so on, cascading outward. You can't pick your own current color, or the bot's current color.
The match ends when there's nothing left to capture. Whoever holds more cells wins.
Level 1 is a solo practice round — just fill the whole board to learn the mechanic. From there, difficulty grows through board size, number of colors, and the bot's strength — from random moves to looking a couple of moves ahead.
