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. Load the game above and it fills the player in portrait. On a phone you can play one-handed; on desktop the frame stays centred so nothing is cropped. Restarting is instant, so there is no cost to experimenting.
