The grid starts as random coloured squares and you own the one in the top-left corner. Pick a colour and your territory absorbs every touching square of that colour, growing outward each turn. You get thirty moves to swallow the whole board, so each choice is a bet on which colour opens the most ground.
Greedy play stalls around move twenty, which is when you work out the real skill is spreading wide early rather than eating the biggest patch first.
