TRIVIA: Inspired by Tony Crowther's BOMBUZAL, the first version of MARBLES developed was called BB BALL and wasn't officially released. A few years later, the graphics were updated, a construction kit was included and the name was changed to MARBLES when coder Ola Zandelin finally released his first complete game to the masses in 1991. When asked what inspired the game, Zandelin had this to say:
"Although I'm from Sweden I grew up reading a lot of British computer magazines like Commodore User and ZZap 64! In one of the magazines there was one of those solution guides to a game called Bombuzal by Anthony Crowther (Ratt). I was a fan of many of Anthony's previous games like Killer Watt, William Wobbler and Son of Blagger, but I never heard of Bombuzal. Without being able to try the game I still got inspired by the idea of a grid-based puzzle game, with bombs and other elements. I kept it in my mind for some time, and one day I decided to try to put something together. The first version was called BB Ball. A few years later when I had improved my pixel skills I decided to reskin the game with better graphics, add a level editor and release the game to the public domain through the 17bit library. The new version was called Marbles." [Source: Ola Zandelin interview, courtesy of AmigaPD].
