Paper io is a fast-paced territory-capture game where every move counts. You guide a colored square across an open arena, drawing trails that turn into your land once you close the loop. The goal is simple: claim more area than your rivals while protecting your own. One misstep, and another player can cut through your trail to eliminate you instantly. Strategic timing, bold expansions, and quick retreats define each match. Whether you prefer cautious edging or wild, sweeping moves, paper io challenges your instincts and pushes you to outthink everyone on the board. Every session brings new opportunities to dominate.
