Slide your finger to aim and let go to drop a Dudu into the jar. When two of the same Dudu touch, they merge into the next one up: Tiny, Shy, Cool, Scarf, Chef, Wizard, Hanfu, Ghost, Knight, and finally Big Dudu. Two Big Dudus pop for a bonus. If the pile stays above the red line for a couple of seconds, the round ends. Your best score and the highest Dudu you reached are saved on your phone. All ten Dudus are pixel versions of the outfits in the Y Build app. The cover art was generated with AI from the game's own sprites.
