How to choose
Most .io games follow one idea: collect things to grow, then use your size against everyone else. Worm and snake games reward careful steering, because a single crash ends the run. Knife and arena games are closer to a brawl, so they suit you if you like to pick fights.
Because a run can end in seconds, the restart matters as much as the game. If you want something slower, try one of the management or fishing games on this page, which borrow the name but are calmer.
