Zodiac Tower introduces a new kind of match-three challenge to casual gamers! As game pieces drop into a holding area on the left side of the screen, you must grab individual pieces with your mouse and place them over groupings of identical items that bear the same shape on a match-three grid to the right. The challenge comes in keep the holding area from filling up as you try to clear away all of the tiles on the right. (Making a match over an item on the grid removes the tile beneath it.) When the going gets tough, you can always use the coins you collect to purchase special abilities, such as a machine that highlights suggested moves. All this engrossing action is wrapped up in a story that has you scaling a sorcerer's tower room by room, collecting the parts for a ship that will allow you to travel through space and time!
