Gaming pundits like to pick on roulette and there are surely many good reasons to dissuade you from playing a game that is cleverly designed to emphasize high risk bets. Most of the betting options on the table are the single numbers and players tend to think in terms of betting only on single numbers when playing the inside.
Savvy players may play the lines in roulette but even when you bet on six numbers the house has a huge advantage over you, and the odds are terrible, too.
Your best chances of winning in conventional roulette strategy guides are to play the “safe” outside bets: black or red, odd or even. Pundits reluctantly agree you can also place bets in the 1/3 categories: 1st twelve, 2nd twelve, and 3rd twelve numbers. These 1/3 groups each pay 2 to 1 odds.
You can improve your chances of winning by playing 2 groups. You reduce the odds to even payoff when you do this but you get a better coverage with this kind of bet (24 numbers) versus the standard safe bets (18 numbers), which also pay even money.
So which way would you like to bet: win even money for betting on 18 numbers or win even money for betting on 24 numbers? Do the math. You may never bet black or even again.
