In Block Drop, you control a gem that jumps around different 3D block formations. Your goal is to remove all of the blocks by jumping off each one leaving only the checkered block behind. The game starts off easy, but very soon becomes challenging because each successive level has bigger and bigger block formations.

Block Drop has a very relaxing atmosphere created by ever-changing sky images and ambient music. All of music in Block Drop is dynamically generated on the fly, so you'll never hear the same music twice.

In addition to the music, all of the block formations are also randomly generated so no two games of Block Drop will ever be the same. Because the levels are dynamically generated, the game can go on "forever" or until the block formations get so big that they crash your computer.
