Lezlee's BlockStacker is a simple and relaxing game that puts a unique twist on the classic game of Tetris. The objective of the game is to build blocks on a playing field and complete rows to remove them. What sets this game apart is the ability to move pieces from one side to the other through the "out of bounds" area on either side of the board.

The gameplay is easy to grasp, with arrow keys used to move the blocks left, right, and down, and the up arrow key to rotate them. This allows for strategic placement of the blocks and the creation of split blocks that can be used on both sides of the board. With this added twist, players can experiment with different strategies to beat the high score.

Lezlee's BlockStacker is a free browser add-on and tool available on the Chrome platform. Whether you're a fan of Tetris or simply looking for a relaxing game to pass the time, this game offers a unique and enjoyable experience.
