Triple Blocks - This game is similar to Block Shifter, but you can't shift the blocks, you can only swap them. The playing field is filled with colored blocks. The object of the game is to remove all the blocks from the playing field. Do this by swapping blocks until three blocks of the same color form a vertical or horizontal line. When three blocks form a line, they are removed from the playing field and any blocks above them drop down. To swap two blocks just position the mouse over them and click the left mouse button.
If your system has 256+ colors, you can easily switch to beautiful ray-traced granite and marble blocks. If your monitor is only capable of 16 colors, you can still play this game with solid colored blocks.
