Hold anywhere and drag to aim: the dotted line shows where the ball goes and its first bounce. Let go and your balls fly out one after another, bouncing off walls and blocks. Each block shows how many hits it takes; every round the wall drops a row, and if a block reaches the line above Dudu, the run ends. Fly through a +1 for one more ball. Every 10 rounds three costumed Dudus offer to join: Ninja goes through blocks, Wizard splits at the top, Knight hits harder, Chef drops rice balls (+1 ball), Astronaut floats up and keeps hitting the top, Fortune Dudu turns blocks into coins, Firefighter hoses a whole row, Doctor takes on bosses, Viking is a bigger ball, and Angel pushes the blocks back once when they reach the line. Their balls fly in turn with yours, each one its own little head; pick one again to level them up. Every 25 rounds a boss block shows up. Too many balls? Tap ×2 or call them all back. Your run is saved on the phone, so you can stop and pick it up later. The Dudus, their costumes and the bosses are the hand-drawn sprites from the Y Build app. The cover background was generated by AI with no characters in it.
