About Tool

Paper IO places you in an ever-changing arena where your objective is to expand your territory by drawing lines out of your base and returning safely so the enclosed area becomes yours. Meanwhile, other players are doing the same and if they cross your trail before you finish your loop, you lose. The gameplay is fast-paced, combining risk and reward: move aggressively to grow, but stay cautious to avoid elimination. It’s designed for quick matches, so you can jump in for a few minutes of intense competition or play longer to climb leaderboards.
