ABOUT COOL TETRIS
Cool Tetris is a classic falling-block puzzle game that brings timeless gameplay to your browser with colorful visuals and smooth controls. Your goal is to arrange falling tetrominoes into complete horizontal lines before the board fills up.
STACK, ROTATE, AND CLEAR LINES
Each piece drops from the top of the playfield in one of several familiar shapes. Move it left or right, rotate it into the best position, and fit it neatly alongside existing blocks.
Completing a full horizontal line clears it instantly, earning points and creating more space for new pieces. Clearing multiple lines with a single placement rewards careful planning and helps you reach higher levels.
As the pace increases, quick thinking becomes essential. Build a clean stack, avoid leaving deep gaps, and use the next-piece preview to plan your moves ahead of time.
