Gem Drop X is an interesting one-player puzzle game for X-Window. Gem Drop X is a direct port of Gem Drop, an Atari 8-bit game written in Action! (a very fast C and Pascal-like compiled language for the Atari). The concept of the game Gem Drop is based directly on an arcade game for the NeoGeo system called "Magical Drop III" by SNK. If you're familiar with games like Jewels, Klax, Bust-A-Move or Tetris, this game is similar to them all. I consider it closest to Klax. (Jewels is like a combination of Klax and Tetris. Bust-A-Move is the least similar, in my opinion, but everyone seems to have heard of it more than the others (except Tetris, of course!)) The game is played with YOU at the bottom of the screen. At the top is a random assortment of colored shapes ("gems"). As time goes on, more gems appear at the very top of the screen, pushing the rest downwards. The game is over when the gems reach the bottom. WWW: http://www.newbreedsoftware.com/gemdropx/
