YoHoHo.io is a battle royale played from above with a cutlass. You wash up on a shrinking tropical island alongside a few dozen other pirates, eat food to grow bigger and stronger, and knock rivals off the island by charging at them — a bigger pirate wins the collision, and a smaller one goes flying into the sea.
The shrinking play area forces everyone together, so a careful start still ends in a scrap. It is fast, has no account requirement, and a round takes a few minutes, which is why it became one of the most-played .io games on school laptops.
Grow early by eating food, avoid fights until you are bigger than the pirates around you, and use the island's edge — pushing an opponent into the water ends them instantly. Last pirate standing wins.
No. Pick a name and play; the game runs in the browser with nothing to install.
It is a browser game with no install, so it runs on a school Chromebook wherever the site loads. It needs a live connection for the multiplayer.
