Vegas style
The most common online casinos accepting U.S. players are advertised as "Vegas style", and often have "Vegas" or "Las Vegas" in the name. As the name implies, they are modeled after the casinos in Las Vegas. Casino payment methods seem to generally be the easiest for U.S. players as well, following standard procedures found in any similar monetary Internet transaction. For the player looking to sign up in a hurry and start playing right away these are a sure fire bet.
Canadian online casinos
Canadian online casinos cater specifically to Canadian players in Canada in every respect. Some accept U.S. players but there are many that do not. Many of them use financial systems for their payouts that do not service the U.S.
When considering a Canadian online casino it is best to check their website thoroughly for country regulations and payouts before opening an account and downloading their online casino software. Also be sure to check software and system requirements at the same time. This information is usually listed on the download or FAQ page but when in doubt contact the casino directly and ask. A prompt reply indicates a reputable casino with good customer support.
European online casinos
European online casinos are generally the most accessible from any country. By and large they not only accept the largest number of currencies but many have up to a dozen different languages including English, Spanish, Portuguese, Dutch, German and Japanese. If a player visiting an online casino sees a collection of flags in an upper corner then the casino is multi-lingual.
Lucky 18 Casino is available in half a dozen languages while Sloto Cash is available in 11 different languages including British, American and Australian English. And yes, the three are quite different. For Americans, and therefore U.S. players, Australian English is closer to British English but with its own slang and idioms, as many and as unique as American English.
Ex-pats are familiar with these differences and may enjoy an alternate dialect but for U.S. players who have never lived outside North America it would be safer to stick with American English when presented with the choice.
Choosing an online casino
Choosing a top online casino is largely a matter of personal preference and taste but can also be a practical matter. Las Vegas themed casinos typically cater to U.S. players and players from other countries wanting a taste of Vegas. The software, payment methods and restrictions are fairly standard for the U.S. and players can expect a smooth transaction in this respect.
Canadian online casinos are geared specifically to Canadians living in Canada and appear to have the most restrictions on U.S. players.
European online casinos on the other hand seem to accept just about anybody who meets the basic requirements of age and valid credit card.
But again these are generalities, not across the board rules, so the player should always thoroughly check out any casino before opening an account.
