Just win because the team that wins gets double potatoes.

Play the game :P

Get more kills.

kill ppl

After someone loses their ammo take the lead.

If you want to earn some potatoes on domination maps without having to fight with other opponents, hide yourself and explode a bomb in close distance when the round is about to finish. You'll be able to earn the same number of potatoes as those who survive in your team. :P
