Paper.io is a brand new .io game in which you need to expand your territory on the map! When the game starts, you own a very small block. But you also control a moving box. You need to capture territory to add it to the block you control. To do so, just form a line and link it back to your owned territory. Be careful not to touch your own line while doing so, because you will die! You can also crush opponents by hitting them while they're forming a line. Start to capture territory step by step.
