The concept is simple. The game is challenging. You collect all the jewels on the screen to proceed to the next level and try to do it in the shortest amount of time. To get to the jewels, you break the colored blocks. If you hit one that is attached to another block of the same color, and it happens to be attached to another of the same color, and so-on, they all break at the same time. However, there are some obstacles. Exploding mines, falling rocks, and in higher levels, objects which appear and disappear and even a night mode. If you are one of the top ten to finish all twenty levels the fastest, you get to put your initials on the board beside your fastest time. Mine was thirty minutes and thirty-one seconds. Can you beat that?. Blockbust is licensed as shareware, the cost of the registered version is $6.95 and full download size is 2.82 MB.
