Older Pyramid/Tile type game...HELP!!!!

I have been trying for almost a year now to locate a game, the worst part is I cant remember what system it was on! It had tiles, and for some reason I feel as if it is in a pyramid type environment. I remember 'sliding' tiles so that some would drop and the object of the game was to line up matching tiles and they would disappear. Sometimes they sat on steps, etc...i remmeber the shapes inside the tiles....i think there were red cylanders, green octagons, yellow diamonds, and not sure what else. If ANYONE has any clue or even an idea what this game is, please help!!!! For some reason I am thinking an old PC game, but am not totally sure. Thank you!!!!!
