Super Gem Drop

Super Gem Drop is a tetris like puzzle game where the objective is to arrange identical gems in groups of 3 or more to keep them from overflowing the screen. You can do that by dropping the gems in the correct columns. Every level increases speed and jewel variety making it harder to arrange the figures.

This is an old game from 2002, so its interface is quite basic, graphics are simple and music/sounds don't bring anything interesting, but the game itself is fun, you can spend a good moment trying to clear your screen and pass to the next level.
It has limited options to allow control of music/sounds volume, high scores and screen mode (full and windowed).

Super gem drop may be a fun choice, but lacks desirable features and additional options, I would definitely not buy it but if you don't care much about graphics and feel like giving it a try, you can get it as a free 60 minute demo version at the developer site.

It works with the following Operative systems: Windows 2000/XP Mac OS X 10.2 or better.
