I can't claim to have invented this but at the suggestion of a respected customer I have added a new technique to Roulette Key Gold.

It's a bit like the capitalist system but only needs a stake of 17 units instead of hundreds.

It's on YouTube but the stakes are not mentioned for the record they are 9, 2, & 6 a total of 17 units

Obviously, its best played on a No-Zero or French wheel but what the hell, in the demo below I've played it with my real money (albeit for half stakes) on an RNG American Wheel.
Don't rely on it for more than a spin or two. My unique, uequalled, guarantee still applies i.e "The longer you play the more likely you are to lose"
