UNTetris

A glowing ball sits on top of a squat pile of uneven blocks. In UNTetris, the usual falling-piece routine gives way to a level-based puzzle set on a small square platform with holes in the middle. Each layout places the ball above a different block structure, shifting the problem from stacking shapes to taking them apart. A bad move drops the ball off the platform. The middle hole stays unreached.

How to play?

Remove blocks one at a time and watch how the structure changes after each move. The ball has to remain on the built area until the last pieces leave it above the center opening. Some removals leave no surface under the ball. The attempt ends if it slips outside the square. Move through the next layouts by sending the ball into the hole in the middle.
