My Fave Iphone Game - Bejeweled 2

Bejeweled virgins, the object of the game is to switch adjacent gems, either horizontally or vertically, in order to line up three or more of the same types to earn points. When this happens, the gems vanish, allowing new gems to fall from above. This can result in cascades, in which gems align by where they fall and more points are earned, the points for each level being represented by a growing bar. A level is won by completing increasingly more sets of gems and lost when "NO MORE MOVES" appears. There's more to it than that, of course.
