How to Play Tetra Blocks

The goal in Tetra Blocks is to rotate and place the falling blocks so that they fill up horizontal lines without gaps. Each completed line disappears, freeing up space and earning you points. You continue stacking blocks, aiming to clear as many lines as possible before the blocks pile up to the top, which ends the game. The challenge is to think ahead and place each piece strategically to avoid running out of room.
