It’s not fool proof and you’ll make very little.
Say you play for £1, forget the 0 and let’s pretend the wheel goes red them black, etc so you win every other go.
After 100 spinss you’ve won £50, it’s taken you 3 hours and you’re making £16/hour minus expenses. You’re not going to break their bank and is it really worthwhile.
??????So them instead of £1 let’s go for £100, with a view to making £5k in an evening. But your run of 6 meant you needed almost £7k of cash on you. What happens if it’s the last few spins of the night, if it goes wrong on just the last 4 that’s £1500 gone.
