About the game
Falling blocks in three dimensions. Drop shapes into a pit with depth and complete a horizontal row, and the perspective takes a little getting used to.
Tetrix 3D belongs to the Falling blocks variant in the Blocks world and joined the catalogue on January 14, 2026. The rules, levels and on-screen language are set by the game’s creator, and a short guide appears on its start screen.
How to play
- Rotate the block as it falls.
- Drop it so it completes a row with no gaps.
- Do not let the stack reach the top.
Tips for a better game
- Keep one column open for the long piece that clears four rows at once.
- Watch the next piece and plan its place before this one lands.
- Holes under blocks are the costliest mistakes, avoid them even at the cost of a taller stack.
