Paper io distills multiplayer pressure into a geometric land race. You surf a cell, streaming a soft line that solidifies into property on closure. Any opponent that taps your open line detonates you. So the entire game becomes controlled, looping lunges: leave safety, encircle, re-enter, bank. The micro-economy is greed versus survival: larger rings risk interception but pay area; tight trims are safe but stall. Rivals carve, flank, and back-stab through razor pixels, so angles, arcs and read-ahead matter more than raw speed. One clean wrap can crown you, one lazy corner can delete everything.
