How to play AltTab Blocks

Place each of the three offered pieces on the 9×9 board and complete a row or column to clear it.

The game ends when no piece fits. Your board and score auto-save, so a reload resumes the same game.

Press Esc to switch to a neutral work-style screen. No sign-up is required and the game has no sound.

At game over, you can optionally submit your score to the job-based ranking. Choose a job category to compare your score with peers in the same field.

Strategy tip: keep as much open space as possible. Clearing multiple lines at once earns a higher score than clearing them one at a time.

A row or column clears automatically when all nine squares in that line are filled. Aim for simultaneous multi-line clears to maximize your score.
