PuzzleTetrominoesTimeWebGPU2.5DAbout Stack
Stack is a falling blocks game. Pieces fall into a well, you move and rotate them into place, and a completed row clears. Clearing several rows at once scores more.
Pieces come from a shuffled bag of the seven tetrominoes, so you never wait long for a specific one. You can hold a piece for later and see what is coming next. The game speeds up as you level, and it ends when a new piece has no room to appear.
The Seven Bag
Pieces come from a shuffled bag of all seven, so no piece stays missing for long.
It Speeds Up
Each level makes the pieces fall faster. The next queue shows what is coming.
Hold and Clear
Keep one piece aside for later, and clear several rows at once for more points.
