Tetris36 is a puzzle game by Antharuu that blends ideas from Tetris and 2048. Pieces fall from above like in a traditional block-stacking game, but the goal is not simply to clear horizontal lines.
Each piece carries a number. When matching values connect, they merge into a higher number, making placement just as important as speed. A poor drop can separate useful tiles or create awkward gaps that become difficult to recover from later.

Tetris36: Number Block Puzzle
Control each falling piece and choose where it should land. Matching numbered blocks can merge, allowing you to create progressively larger values and increase your score.
The challenge comes from managing two things at once: finding useful merges and preserving space. Chasing every available combination can quickly make the board uneven, while placing blocks only for convenience may leave matching numbers too far apart.
As the board fills, each decision becomes more restrictive. Good runs depend on arranging numbers so that future pieces still have several useful landing positions.
