Hamster is a single-player idle clicker centered on a simple, oddball premise: click a hamster to make it shiver. Its defining twist is that each click can push the shiver level either higher or lower, turning a familiar repeated action into a small game of chance rather than a guaranteed climb.
The counter tracks the hamster’s shiver level, which the description says can range from zero to infinity. Alongside clicking, players can collect different hamster types for their Steam Inventory, with a new hamster drop available every 90 minutes; collected hamsters can also be used as in-game skins. That pairing of incremental clicking and cosmetic collecting gives the game its particular rhythm.
The game’s stated design is casual and deliberately focused: click, watch the random shiver result, and build a collection of hamster skins.
