Tetrix Online: Stack, spin, and clear lines!
Tetrix Online is a fast, colorful Tetris-style puzzle game where you rotate and stack falling blocks on a grid to complete horizontal lines and rack up points. Blocks fall faster as you climb through the levels, so every move counts when the grid starts to fill up. Whether you have two minutes or two hours, the chase for a high score makes every drop feel like a tiny high-stakes puzzle.

Did You Know?
Tetrix Online borrows the same falling-block DNA as the 1984 Soviet classic Tetris — the original was programmed by Alexey Pajitnov on a Soviet Electronika 60, and the simple 'rotate, place, clear' loop has remained one of the most cloned puzzle formulas in gaming history.
Key Features

How to Play Tetrix Online
Blocks fall from the top of the screen one piece at a time, and your job is to move and rotate them to complete full rows. When a line fills from edge to edge, it disappears and you earn points. The game ends when the stacked blocks reach the top of the grid, so clear lines quickly and leave gaps for future pieces. Use hard drops when the spot is obvious and soft drops when you still want to slide a piece into place.
Disclaimer: These are the standard controls for this type of game on PC Browser with Keyboard/Mouse. The actual controls may be slightly different.
| Action / Purpose | Key(s) / Gesture |
|---|---|
| Move Left: A or Left Arrow. Move Right: D or Right Arrow. Rotate: W or Up Arrow. Soft Drop: S or Down Arrow. Hard Drop: Spacebar. | |
Tips & Tricks
Leave one column open on the right (the classic 'T-spin' setup) so you can slide I-pieces in to clear four lines at once for huge points.
Don't flatten the top of your stack. Aim for a bumpy, even surface so the next piece always has a clean place to slot in.
Hard-drop a piece only when you are 100% sure of the spot — a fast hard drop into the wrong column is the fastest way to lose.
When blocks speed up, switch focus from scoring big combos to surviving. A clean, even stack beats a fancy line clear that leaves gaps.

Frequently Asked Questions
Discuss: Tetrix Online
Honestly the cleanest Tetris-style browser game I've played. Controls feel responsive and the speed-up curve is fair, not brutal.
Addicting. I sat down to play 'one round' and an hour disappeared. The 5-piece preview queue really makes you plan ahead.
Great pick-up-and-play puzzle. Works perfectly on my phone during a commute — keyboard works fine when I switch to my laptop later.
