In Hamsterio, you dive into an arcade survival adventure starring a hamster in a backyard transformed into a vast wilderness. Here, blades of grass tower over buildings, and insects loom as large as dogs. The hamster dashes into action — you guide it to evade enemies and gather food. Waves of ants, pillbugs, wasps, snails, spiders, beetles, toads, moles, and moths threaten your path. Eating snacks boosts your level, unlocking the choice between weapons like seeds, orbiting acorns, popcorn mines, a nut mortar, static fluff, spicy breath, stinky cheese, or a bubble, and charms such as sneakers, a chonky tummy, an acorn helmet, a ninja headband, cool shades, a lucky clover, a hero cape, or a snack backpack. These upgrades also alter the hamster's appearance.
How to play
In Hamsterio, your hamster launches attacks automatically — your task is to manage its movements and ensure its survival.
To move, use the WASD keys or the arrow keys. On a smartphone, swipe on the left side of the screen or use the left stick on the gamepad.
Perform a dash roll with Space, Shift, or the A button on the gamepad — this makes the hamster invulnerable for a short time, allowing you to pass through danger.
Collect food: bugs leave corn, blueberries, and strawberries behind. Gather them to gain experience and level up. Cheese restores health, the magnet attracts all snacks, coffee boosts your speed temporarily, and a firecracker clears the screen. Smash cookies to get loot.
Choose upgrades on each level by selecting a card with numbers 1–4 using the arrow keys and Enter, or with the mouse. The reroll button offers new options.
Watch out for boss attacks — they signal their powerful moves, so pay attention to the ground and avoid the attack line.
