Tetra Blocks is a classic Tetris game where players need to place various shapes of blocks in a rectangular game area to create a complete horizontal row. When a row is filled, the row will be cleared and points will be earned. The goal of the game is to clear as many rows as possible before the accumulation of blocks reaches the top of the game area.

It will test your spatial imagination and responsiveness. In this game, you need to control the constantly falling blocks and place them in the bottom square to form a complete horizontal line.

Players can use the direction keys on the keyboard to move the blocks left and right, and press the direction keys to accelerate the falling speed of the blocks downwards. Players can also rotate the blocks to adapt to different spatial layouts. When a block falls to the bottom or overlaps with other blocks, it will be fixed in the game area.

In Tetra Blocks, players need to flexibly think and make decisions in order to place the blocks in the most suitable position. If the player is unable to clear the blocks in a timely manner, the game area will be filled with blocks, leading to the end of the game.

Tetra Blocks has multiple game modes, including Classic mode, Challenge mode, and Endless mode. In classic mode, you need to eliminate as many blocks as possible in a limited amount of time. Challenge mode provides a series of levels, each with unique challenges waiting for you to solve. Endless mode is a mode that constantly challenges one's high score record.
