The Best Online Roulette Casinos

A good welcome bonus can elevate an average casino to a great one. However, it can be difficult to determine which bonus is best. There's more to it than the stated cash value of the bonus.

Many gamblers make the mistake of thinking that the higher the match percentage, the better the bonus. While a high match percentage is good, you also have to factor in the amount of wagering that you have to do and the games that contribute to the wagering requirement.

Even if the match percentage is high, it can lose overall value by having strict wagering requirements or by not offering a good contribution by the games that you like to play. Keep these in mind when making your choice on where to play  — we'll always help you find the best welcome bonuses in our casino reviews.

Roulette was invented by Blaise Pascal, a French mathematician in 1655 during his research into a perpetual motion machine. By 1796, the game was played in French casinos though the early roulette wheels had both a single zero and a double zero. In 1843, two Frenchmen François and Louis Blanc added a single 0 roulette variation in the German casino Bad Homburg. This made the game more profitable for casinos by lowering the house advantage and therefore making the game more attractive for players.

Roulette Arrives in America

By the late 1700s, New Orleans becomes the gambling capital of the US. And thanks to French immigrants, roulette quickly became one of the most popular games in Louisiana. Early roulette tables in the US were a bit different from what you see today. Instead of 38 numbers including 1 through 36, 0, and 00, the roulette wheel has 28 numbers, two zeros, and a symbol of an American Eagle. The last symbol gave the house an extra edge of 12.9%. Casino players weren't thrilled, so the American Eagle was quickly nixed.

But because US casinos wanted the extra edge, they opted for two zeros on the roulette wheel instead of the standard single zero used at European roulette casinos. The extra zero gives the house a bigger advantage, which is why many casino players prefer the European to the American roulette variation.

Roulette History: Online Roulette

In 1996, the first online casino hit the Internet. The available games were limited to a handful of slot machines and a couple of blackjack tables. It took a few years for roulette to follow, but once people discovered how thrilling betting on red could be from the comforts on home, playing roulette would never be the same.

No longer would players be forced to play just one type of roulette. The top Internet casinos offer the American, French, and European varieties, so you can literally feel like you're playing in a casino in any part of the world that appeals to you.

We've come a long way from a physicist trying to invent a perpetual motion machine. Today, roulette players can place bets from iPhones, iPads, Mac, PCs, or pretty much any other device they own.

But there are a lot of roulette players who still crave the type of human interaction that you just can't get from ordinary online casinos. That's why many Internet gambling sites have evolved to include live dealers. Instead of computer-generated graphics for the wheel, a live dealer spins an actual wheel via a webcam. This isn't some live dealer in a dark warehouse. The top online roulette sites use real dealers based in actual casinos. It's the closest thing to being in a real casino.
