Dumbubu is a free idle game where you abuse a desktop pet to generate randomized loot boxes, with the appeal of potentially profitable Steam inventory items. The core loop involves minimal active engagement—torment your creature, collect blind boxes, and hope for tradeable rewards. It's designed for players seeking passive income through Steam's economy rather than traditional gameplay.

A low effort Idle game in a long line of them all about Steam inventory items to make money with no over-sight for poor gaymers.

At least you get boxes for free and open for free.
