Tetrollapse

Retro blocks return in Tetrollapse. Old-school phone puzzle energy carries through every board. Four-square pieces drop in changing shapes above a grid that isn't empty when a round begins. Packed leftovers already sit on the play area, forcing careful placement from the first drop. Progress comes only after the whole stack has been erased from the board.

How to play?

Fit each falling piece against the blocks below, filling horizontal rows without leaving holes. A completed row vanishes at once, cutting down the pile and freeing space for the next shape. The panel on the right shows the upcoming figure. Use that preview to place the current piece with less waste and finish every board.
