Red Out is a sliding block puzzle with various sizes of sliding blocks. The object is to get the big red block to the bottom center of the game board. To get it there, you will need to slide the blue blocks out of the way. To slide a block, click on it. If there is only one place the block can go, it will slide into place automatically. Otherwise, you will be asked to click on the space where you would like to slide it. Source: The Game Website.
