I played it a lot, back in the day. My best score ever was one night when I came home from an event at about 2:00 in the morning, dead tired, and decided to play one game before I went to bed. The game went on, and on, and on, and I hit a new high score that I was never after able to beat.
Jezz Ball originally was part of the Windows Entertainment pack for Windows 3.1 -- came on some 3 1/2 inch floppy disks with a few other games, screen savers, etc. But, according to this web page: www.jezzball.com/get.htm, M$ eventually started licensing it to OEMs to include on new computers for free, which is probably how you got it.
The web pages also says that the game only works well on a 486, which is not hard to believe. A lot of games from that era were tied to the processor speed rather than to actual system time, and running them on faster processors made them unplayable, assuming they would even run on the newer versions of Microsoft's notoriously incompatible OS "upgrades". I remember trying to play the original "Lode Runner" on a 386. It was written for an XT, and it ran like a squirrel on 1/2 ton of speed. Whoa.
The aforementioned web page has links to a number of potential Jezz ball lookalikes. Don't know how many of the links are still good. Good luck finding one you like.
