Have just signed up to this forum - not sure if this is the right place to make my first posting, but I'll leave it to the moderator to move this post if I've got it wrong.
I've been running a hobby web site since 2012, dedicated to lots of stuff gambling (in the main in the UK), and as part of this I've offered up various pieces of spreadsheet work I've created for use by others. Two of these relate to roulette and may be of use to contributors here; a roulette simulator that can simulate up to 10 million spins (uses the RNG built into Excel) and an evens-payoff positive progression system that can be tested on a step-by-step basis for each cycle and trialled using the simulator function. All of the downloads from my site are freebies, so I'm not try to plug anything here that requires money to change hands. Any issues around posting a link to the downloads page here?
On a slightly different note, my first experience with a wheel of doom was on my first visit to a casino (at the ripe old age of 47) when I dropped a single chip on to ten black, and it came up. If I'd walked away at that point I could have been satisfied that I was a roulette winner, but I didn't and overall I'm not. No surprise there I think. Despite the odds against winning longer term, I still enjoy sitting at the felt on occasions and blowing the odd score or two and watching the antics of others at the table - although I don't do it too often nowdays. My most recent visit to a house of chance was around eight weeks ago (a pretty depressing experience), and before that over a year prior.
Best of luck at the felt.
