Tetromino Attack
About Tetromino Attack
Tetromino Attack brings the timeless Tetris formula into a battle format. Arrange falling tetromino pieces to complete horizontal lines, which clears those rows and sends garbage blocks to your opponent's board. The last player with a clear field wins.
The battle twist transforms a solitary puzzle into a tense competitive experience where every efficient clear is both a personal win and an attack on your rival. Learning to set up combo chains — multiple line clears in quick succession — is the skill that separates good players from great ones.

How to Play Tetromino Attack
Use arrow keys to move falling pieces left and right.

Complete horizontal lines to clear them and send garbage to opponents.
Don't let pieces stack to the top — game over if they do.
Tips & Strategies
- Keep your stack flat and low. A flat, even surface gives every incoming piece a valid placement without awkward gaps.
- Save the I-piece for Tetris clears. Clearing four lines at once sends the most garbage — save it and maintain the right-side gap for it.
- Think ahead using the next-piece indicator. Always be planning where the current piece goes based on what's coming next.
