Monster Paper.io turns land-grabbing into a tense game of risk and reward. You steer a little monster across a colorful map, drawing trails to claim new ground, and every extra stretch you claim is another chance for a rival to catch you.
Move your monster with the keyboard arrow keys. Leave your zone, draw a loop, and return to your territory to claim everything inside it. Collect diamonds as you go, and aim to cover the whole map, since reaching 100% unlocks new characters and bonuses. Be careful: if an enemy touches your trail while you are outside your zone, the round ends.
Claim your corner of the map and play Monster Paper.io free on Games321, right in your browser with no download.
