About Tetra Blocks
The game mechanics are simple and easy to understand yet challenging to master. Your objective is to fit Tetra blocks of different shapes into a line without any gaps. With each completed line, they’ll earn points and move on to the next level. The higher they go, the faster the blocks fall – so they must be quick on their feet!
How to play Tetra Blocks
There is very little to learn before your first run. You will want a keyboard for this one — the arrow keys / WASD carry most of it, and the table below has the rest. Portrait layout: hold the phone the way you normally do, or play it centred in the page on desktop. Expect the first attempt to be a write-off; that is normal here.
Controls
| Input | Action |
|---|---|
| Mouse | Navigate menus and interact |
| Arrow keys / WASD | Move |
| Spacebar | Primary action |
On mobile: Tap and swipe directly on the screen. The game is built for portrait, so you can play one-handed without rotating your phone.
Why it is worth playing
The reason Tetra Blocks holds up is restraint: it takes one idea — block & tetris-like — and builds the whole game around it instead of padding it out. That is the whole pitch, and it is enough.
