Slash Battle Io is a fast-paced multiplayer io game where you control a colorful stickman in an arena. Your goal is to collect weapons, defeat other players, and climb the leaderboard to become the top fighter. The game features simple controls, various weapons (like spiked maces and chainsaws), and dynamic battles where every move counts.
Slash Battle Io delivers exactly what io game fans love—quick, chaotic fun with easy-to-learn mechanics and competitive thrills. The weapon upgrades (from spiked maces to chainsaws) add a satisfying layer of progression, and the leaderboard keeps you hooked to climb ranks. While it’s simple enough for casual players, the fast pace and player interactions make it endlessly replayable. The only minor nitpick is that matches can feel a bit short, but that’s part of the io game charm!
Highlights:

Stickman party! All players circle up like they’re about to play a tiny, violent game of musical chairs.

Blue stickman gets his first big weapon—look at him swing that spiked mace like it’s a toy (spoiler: it’s not).

Chainsaw king! Our blue hero rocks a crown and a chainsaw—now he’s both royal and deadly.

Rescue? The game asks if you want to respawn, but who needs help when you’re a chainsaw-wielding king?

1st place! All that slashing paid off—time to flex that golden '1ST' badge like a stickman boss.
Instructions:
Move your stickman using the arrow keys (or touch controls on mobile). Collect weapons from glowing spots to upgrade your attack. Swing your weapon to defeat other players—be careful, they’ll fight back! Stay alive, climb the leaderboard, and aim for 1st place!
