ONLINE SLOTS FOR USA PLAYERS



Club USA Casino is the highest rated site here at OCS. The fact that Club USA offers a wide range of daily slots tournaments with buy-ins for as little as $1, certainly plays a factor in giving this long-running online casino the esteemed title of being the Best. However, it's their track record for providing exemplary customer service, fast payouts and and some of the best bonuses and ongoing promotions we've come across that makes Club USA a great casino to join - slots tournaments or not. That said, if you are indeed looking for an active U.S. friendly online slots tournament schedule with large winnings, low-risk, and moderate competition, Club USA is out top pick. Sign up today to start receiving special coupons for receiving tournament chips, not to mention some great welcome bonus offers that include a 100% Slots Bonus worth up to $777 Free. We highly recommend Club USA as a top online destination where you can play free online slots games. Click here to visit Club USA



Slotter Casino is the OCS top choice for providing mobile slots for US bettors. While players from around the world can access the 20+ selection of mobile enabled games here, there are just a handful of US-friendly casinos online that offer mobile casino games, let alone a decent selection of slot machines, including those with progressive jackpots. …..Aztec’s Millions…., for example, is a popular RTG slot machine consistently topping the $1 Million mark. Being optimized to render properly on cellular phones and tablets, means players can win thousands of dollars on a single spin with a mobile device at Slotter.



Reel Spin is fast becoming a popular Real Time Gaming powered online casino with U.S. players. The RTG software platform consists of 100+ online slot machines, that include traditional 3-reel machines, mutli-line video slots and progressive jackpot slots. Taking full advantage of this offering, Reel Spin offers a great selection of ongoing reload bonuses that can be used for wagers on slots, including daily specials with reasonable play-through requirements that can be claimed multiple times in a single day. New players are eligible for a $888 Welcome Package for use on slots wagers.



ONLINE SLOTS TOURNAMENTS FOR US PLAYERS


 

Slots LV is a Real Time Gaming powered, USA friendly online casino with an emphasis on the slots. To that end, Slots LV offers daily tournaments with prize pool winnings. The buy-in's for these tournaments are generally no more than $3, with $0.50 rebuys. Within the slots tournament section of the software platform (available in Flash and download), the date of the tournament, buy-in amount, status (registering or announced) and the number of players signed up is posted. The great thing about these slots tournaments is that the turnout isn't so much that heightened competition makes it more difficult to win money, and yet enough players do take part to make the prize pool the worth going after for a daily tournament.


ONLINE SLOTS TOURNAMENTS FOR UK/EURO PLAYERS



Euro Palace's Slot Masters is our top choice for slots tournaments, period. As their name implies, Euro Palace caters to and is frequented by European online gamblers; So much so, slots tournaments with large, guaranteed winnings are the norm here, each week adding up to $32,000 in guaranteed prize money. Tournaments include exclusive freerolls, extender tournaments, one-shotter's, and reloads - each offering a daily selection that would keep a full time slots tournament player busy. There is a great Beginners' Guide tutorial (given by Tomb Raider Slots' Lara Croft, herself), which gives the full lowdown on the Slot Masters tournament scene at Euro Palace.


Mr. Green Casino is one of the largest no-download casinos in business today, and the #1 Rated UK/Euro Casino here at OCS. Hosting daily low-risk tournaments with guaranteed cash winnings, this is a a great online destination to have some fun playing slots - tournament style - yet keeping the competitive vibe down to a minimum. Truth of the matter is that most online casinos host slots tournaments as a means to milk as much money as possible from participating players. But not Mr. Green. Taking operator responsibility to the next level, Mr. Green Casino does not facilitate players getting in over their heads. The promotions and tournaments that take place are designed for player enjoyment, and have less overall red tape. Another reason why we like Mr. Green is that, being an integrated software platform, there is a great selection of casino games from Best Soft, Wager Works and Net Entertainment.



Following the record-breaking $1 Million "Grand Slam of Slots" last year, which was the largest online slot tournament ever held to date, All Slots Casino is back hosting several daily tournaments with guaranteed winnings in the hundreds and thousands. The popular $150 "All Day Loaded" real money online slot machine tournaments are now open to players. Read the OCS All Slots Review for more information.


ONLINE SLOTS TIPS

While you could say that Las Vegas was built on the slots, in reality, Las Vegas was built on the House Edge, which is present for all casino games. Slots may not offer the opportunity for strategy, but they certainly facilitate entertainment and an opportunity to relax and take a mindless break away from the card tables. They also offer some of the largest jackpots to ever be won on the Web. If you play at an online casino listed on onlinecasinosuite.com then you can playing comfortably knowing that you are playing at one of the absolute best of the best casinos on the web.

Online slots come in many shapes and sizes, the bulk of which are multi-line video slots. At online casinos, you are most likely to find a selection of three-reel single-payline slots and a host of five-reel video slots with twenty-something paylines or more. You will also get a fair selection of progressive jackpot slots from the leading software companies.

Depending on the online casino software provider, the overall selection of slots will vary. Microgaming certainly offers one of the largest selections, not to mention uniquely designed slots on the Web (see our new Microgaming slots reviews below). However, with innovative interactive features like those of Rival Gaming software, overall selection is obviously not the only factor in choosing an online casino to play slots at.

Just as if you were scouting out slot machines at land-based casinos, it is wise to pay attention to the payout percentages on the slots. Not all online casinos publish these (which should be prepared by independent, third party auditors), but of those that do, like eCOGRA approved casinos, the previous month's payouts for slots will be published. The competitive range is in the mid to upper nineties percentile. Also, don't frustrate yourself trying to find hot or cold slots. Contrary to some false rumors, slot machine payouts are not contingent on previous spin results.

Immediately below are in-depth previews of Microgaming Software's upcoming slot machine releases, which come out every month as part of Microgaming's "New Games Rollout" campaign. No other software developer releases, nor has as many slots in their portfolio as Microgaming. Immediately below these reviews you will find additional slots tips and updated slots news and articles.
