Basic game involves clearing the field as the tiles come up from the bottom but the trick is that you can only move them horizontally not vertically. They have a couple of different modes that add different wrinkles to it and several different backgrounds and tile sets to choose from for variety but basically it is all the same game. Fun but it does get boring after a while.
I wish I had found Game Fly FIRST and just rented it, but unfortunately, I paid good money to buy this game! I did not find the graphics up to par with other games I own. It was too "outer space" style graphics for my taste. I also didn't care for the music or sound effects. This might appeal to a younger crowd. Also, it became very boring in a really short period of time! I would GIVE this game to anyone who might want it, that is how much I disliked the game.
After playing this for a little while I enjoyed it at first. Then it got to be the same thing over and over. Switching modes didn't make much difference for me. One thing I thought was funny was I never would give up trying to play it like bejeweled and it didn't work that way.
