Knife.io

Knife.io is a competitive browser battle where spinning blades are your way to survive. You guide your fighter through a crowded arena, gather additional knives, and use rotating weapon movement to challenge other players.

The appeal comes from turning simple mouse control into quick decisions about positioning and attacks. Each encounter can change as opponents move nearby, so collecting blades and choosing when to engage are both important parts of the action.

Use the mouse to guide your character around the play area.

Move toward available blades to add weapons to your collection.

Bring your spinning attack close to rival fighters to defeat them.

Stay active in the arena and try to remain the surviving player.
