Tetris Worlds

Grid space shrinks with every falling tetromino. Tetris Worlds trades idle play for constant planning, since one bad placement can clog the stack and end the round fast. Logic stays in motion from the first piece. Score climbs when full horizontal rows vanish, and higher ranks speed the descent.

How to play?

When a piece appears, rotate it before landing and slide it into the gap that fits. From the upper-left reserve, swap in the stored shape once if the pile needs a different match. On the right side, the preview queue shows the next 3 or 4 pieces. Read that sequence ahead and build rows that disappear on contact.
