Tetris 99: 10 Essential Tips & Tricks The Game Doesn't Tell You

4. Don’t Panic Over Single Gaps In Lines

Tetris is about clearing full lines. Unless you’ve been living under a rock for the past thirty-odd years, you should know this.

However, managing to misplace a tetromino or being given a piece that doesn’t snugly fit anywhere and consequently leaving a gap isn’t the end of the world. Don’t panic.

Continue building and clearing above, and once your gap re-opens from clearing the line directly above it, based on the piece you currently have, you might be able to clear that next line with your next piece, resulting in a combo.

Being inaccurate isn’t ideal, but sometimes gaps being left can result in a natural setup for a three, four, or higher line clearing combo. This can lead to a significant stack of lines inbound to whoever is being targeted.
