O-Block

An O-Tetromino (Often called a square) is a tetromino arranged in a perfect square. If it is rotated, it does not change. It is always two blocks in length by two blocks in width. This piece is quite troublesome among others, and mainly because it cannot fit in any jagged areas in a player's matrix. However, in combos, they can be quite useful.
