Stoneium is a very nice block/stone moving online puzzle game by Flonga.com
Object of Stoneium is to remove all the stones on each level, by connecting stones of the same color. Each level consists of a number of stones connected together on a game grid.
Use the mouse to move the stones you can match up the different colors. If you connect two or more stones of the same color, they will disappear and the surrounding stones will move in to fill the gaps.
This all sounds and look very easy, but you really need to plan ahead. Happy Puzzling!
