Paper io online is a brand new .io game where you have to expand your own territory on the map! When the game starts, you have a very small territory. But you also control a floating box. You must capture the region to add it to the block you control. To do this, just draw a line and connect it back to your area. Be careful not to touch your own line while doing this, because if you touch your own line, you die! You can also destroy your opponents by hitting them as they form a line....
