Use your mouse to select what block you want to slide across the board, and move your mouse in the direction you want the block to slide. Add up each number in the blocks on the board and match them to make the sum of the two blocks add up to nine. Take heed in this mathematic puzzle game though as blocks will need to have numbers added and taken away. Take away numbers by sliding your blocks into other blocks that have minus signs in order to reduce the number on the block. See how many blocks you can make to match the number nine! 9 Game is presented to you by SolidGames.com.
