How this collection is selected

A recognised .io source category or a title ending in .io is required. The letters 'io' inside an unrelated title, slug or description never count.

Matching rules and catalogue evidence reviewed 27 August 2026.

Device and controls

Desktop mouse and keyboard controls often provide the clearest arena view. Mobile support depends on whether the individual game supplies touch controls.

Movement may use a mouse pointer, WASD, arrow keys or an on-screen stick, with extra actions shown inside the game.

Choose a session length

Arena rounds can end quickly, but stronger runs may continue for longer while you collect, survive or compete.
