Don't Risk Your Gambling Money
There is no need to risk your gambling money piece you're testing. Go to an online casino and play for free, or, in a live casino, stand near a table with pen and note pad, record a series of consecutive spins, and then see how you would be have done, had you been playing.
The Computer network is flooded with ads for roulette systems. They all claim that you'll "win consistently" once you play roulette. Most of these systems sell for anyplace from $200 to some thousand dollars. Do they work? Do you get your money back if it turns out they don't work? I doubt it.
And don't spend big bucks. Simply because information is high-priced doesn't guarantee it'll do you a better player or a bigger winner.
