Start a new game:
Preset openings (host only β collectors fixed, P2 picks the colour):
Host (P1) places both collectors. Joiner (P2) then picks a colour β host plays the other and goes first.
Load opening / Preset openings (host only): discs and both collectors fixed β no live placement, P2 still picks the colour.
Collect discs on a 12x12 grid to score the most points. The game continues until all discs are collected or both players cannot move.
