Being a retired programmer, and also the proud owner of a new repro Fivewin, I decided to write a little program to investigate. By little program I mean what I call a gadget, that is something to do just the job at hand and not be an all singing all dancing application.
I obviously wrote the gadget for a Fivewin. By simply clicking on a button for each ball channel for just one of the standard payout schemes, I was able, from the calculations the gadget performs, to get a rough feel for how all the standard schemes, including the free ball variation, payouts compare. (Don't use the 4/2/6/2/4 option, you will have a losing machine!)
I have seen Fivewin style machines which have a central Lose hole similar to the Elevenses etc. I allowed an option for that, even though it was actually of no use to me! Just call me thorough!
Out of curiosity, I also created a similar gadget for the Win & Place style machine as the input data is the same, a ball hitting one of 7 channels. So for example, I can see how these machine's payouts compare to a Fivewin.
As I have always belonged to that section of the software community that believes in free software, I have put download links for these two gadgets on to the Freeware page of my web site (it contains only programs that I have written for my own use). So if any of you also have nothing better to do than record Allwin outcomes then please visit the bottom of http://racingdog.hostfree.pw/Freeware.html and look for the Fivewin Analyser and Win & Place Analyser links.
I was vaguely thinking that one day it wouldn't be too much trouble to produce a gadget for the Elevenses machines, or any other sensible suggestion from the readership here!
