Before you play online roulette free games, a crucial decision must be made. Should you play online roulette flash games and cash games in the American or European style? Generally speaking, and where an option exists, you should opt for the European wheel, which has only 37 slots (1-36 plus 0). American wheels have a 38th ‘00’ slot, which greatly increases the house edge.

The reason for this has to do with odds. Zero pockets have no value for players, as they do not yield wins. Thus, as you add more and more zero pockets, you increase the house edge and decrease your own chances of winning. 

When you play online roulette with a European wheel, the house edge is 2.63%. When you play online roulette with an American wheel, the house edge shoots to 5.26%. If you play online roulette for an hour, this 1.5% difference isn't substantial. If, however, you play online roulette for an hour EVERY DAY, you will notice a sizable difference in your winnings between the two. Where you have the choice, always play online roulette with a European wheel.

Additionally, forego the “betting system” when playing (whether practicing at a free online roulette game or enjoying a real cash roulette download game) espoused by your neighbor’s best friend’s cousin who won a million betting according to its rules. Frankly, no such betting system exists. A ball spins around a wheel and stops when it loses momentum.

Unless your betting system accounts for both randomness and centrifugal force, it’s a losing proposition. Wager wisely and walk out when your wallet’s thicker than when you walked in. That’s a betting system.

Many of the top gaming sites issue free bonuses with no deposit required, which means you can take a spin at a real money game without any risk. Both Titan Casino and Europa Casino are currently offering $/£/€ 10 free to players who get to the site via Gambling City. Good luck and wager wisely.
