Turf

run out of your colour and back: the loop is yours. cut a rival's line to take their land.

steer a runner out of its patch and back again on a crayon map of India: whatever your line encloses becomes yours, a rival touching your open line pops you, and touching theirs takes their land

Leave your colour and you draw a line; come back to your colour and everything the line closed off is yours. While the line is open it is your weak spot: a rival running into it pops you, and you running into theirs pops them and hands you their land. Bigger loops take more and stay open longer. Take half of India to plant your flag, then 55% of Brazil and 60% of Australia; 100 seconds each.

Concepts: area, maps, risk.
