Hello and thanks for your interest in my ditty.
Its aim (as revealed in in the verbose accompanying notes which only the bravest can survive reading) was to write a simplistic dice rolling routine and port it on all the 8-bit systems I had the chance to lay my hands on when I was a kid (plus a few more) with as little changes to the code as possible, so given it has to run on a 1K ZX-80, it is somehow expected that it does not take advantage of the capabilities of the more powerful machines.
And it is what it is: just a substitute for a pair of actual dice which happened to be nowhere to be found in the whole household (still are). So there is no built in game to win or lose, that is up to the player to provide ?
Cheers (but no cheeseburger for me, just a beer, thanks!) ?
