Gem Drop X is a classic Puzzle Arcade Game for Power PC Mac OS / Linux / Palm / Dreamcast
Gem Drop X is a fast-paced puzzle game where it's your job to clear the screen of gems before they squash you! (You're at the bottom, they're at the top, and they keep coming!)
Gem Drop X was directly ported from the original GemDrop for the Atari 8-bit, which was based on "Magical Drop III" by SNK.
You grab gems (up to 10) of the same color and use them to knock more gems off the screen. Match 3 or more of the same color in a column and >BAM!< they explode! Any adjacent gems of the same color also explode, causing a chain reaction that might cover the entire screen!
The more gems that disappear with one shot, the higher the score you get!
