About game
Fans of chaotic io games will find a new obsession in Hamsterio as you navigate a backyard turned into a colossal obstacle course. Your tiny hamster faces off against oversized garden pests while you scramble to stay alive against endless waves of insects. Movement is the only thing you control since your rodent automatically fires at any threat that gets too close. Dodge snapping beetles and hungry toads by rolling through the grass to avoid their attacks. Collecting fallen snacks like corn or strawberries boosts your level and grants you powerful combat upgrades. You can equip items like orbiting acorns or spicy breath to clear the screen faster than before. Each run feels different because your gear choices change how your hamster survives the backyard wilderness. Jump into this frantic survival challenge right now in your browser without any installation required.
How to play
The hamster attacks on its own — you handle movement and survival.
Move with WASD or the arrow keys. On a phone, drag on the left side of the screen or use the gamepad's left stick.
Dash roll: Space, Shift or the A button on a gamepad. A short roll makes the hamster invincible, so you can roll straight through danger.
Food: bugs drop corn, blueberries and strawberries. Collect them for
experience and levels. Cheese heals, the magnet pulls every snack in, coffee speeds you up briefly and a firecracker clears the screen. Smash cookies for loot.
Upgrades: on each level pick a card with 1–4, the arrow keys plus Enter, or the mouse. The reroll button deals fresh options.
Bosses telegraph their big attacks — watch the ground and leave the attack line.
