Online Slots

Online slots carry the best opportunities for winning a lump sum of money and no complex calculations are needed to prove that point. Let's compare the most popular casino games: The max prize in blackjack is 3 to 2 (for hitting a natural blackjack) unless a game with bonus payouts is played, e. g. Match 21 from RTG in which you can win 40:1. Roulette, another sought-after option, awards the maximum of 35 to 1 if a Straight bet wins. Now about casino slots: a normal, non-progressive slot with five reels can provide a win of 5000 times the total bet, and higher. If the player bets $1 per spin, he can scoop $5000 in a lucky spin, quite apart from eye-popping progressive slots with seven-figure dollar payouts.

Video slots have been entertaining US gamblers for quite a while. Not only does their unmatched popularity, as compared with other games, stem from big winnings. Players are also driven by their visual design, fun and immersive gaming experience. There are many thousand video slots as of today and most of them are unlike each other. First of all, they differ in graphics but most importantly, there are original mathematical models behind each, and this is what makes real-money slots increasingly lucrative for players of the United States.

Brief anatomy of online slots

A symbol is the smallest element and main constituent of every slot. This is a small, usually thematic picture that is used in the gaming process. An ordinary real online slot has around 10-12 symbols. When opening any slot, a player will see symbols are arranged in a specific form, and most often they create a rectangular with 15 symbols visible at a time (5x3). Some slots have 6 columns (reels), while classic slots tend to come with three reels.

Almost every slot has a preset number of paylines, though numerous slots have none (these are based on a 243 or 1024 Ways To Win principle). A player first needs to select a bet size paid on each spin and this is done by configuring a few values: the number of paylines, coins per line and coin size. A typical real-money online slot enables one to wager one cent up to a few dollars per line, therefore slots are affordable to almost everyone.

When the bet is adjusted as needed, the player clicks Spin to begin a round. After the reels stop, the player will collect winnings, if any. A certain number of coins is usually paid for specific combinations of symbols, the full list of which is available in the paytable. You can change a bet size at any time between spins.

Main types of casino slots

Games with five or more reels are normally called video slots and this is the most widely spread type. A video slot tends to have a few bonus features, appealing graphics and animation, high bet sizes, many paylines and high winnings. They make up the core of every online casino.

Three-reel games are considered to be classic slots because of their resemblance with authentic slot machines invented over 120 years ago. They have a simple structure of the active game area with only three reels, a very few lines (normally, 1 to 5, or nine in rare cases) and a limited range of bonus features (or none at all). There is a small subgroup of so called AWP (Amusement With Prizes) slots that have three reels and a whole lot of bonuses including Nudge, bonus trail around the reels and sometimes a second-screen game.

Real online slots with an increasing jackpot value are known as progressives. Jackpots grow from players' real-money bets. Some notable games are Shopping Spree (RTG), Major Moolah (Rival), The Glam Life (Betsoft) and Aztec's Millions (RTG). As a rule, a minimum bet to stand a chance to grab any jackpot is a bit higher than in non-progressive slots.

Some real-money online slots are described as 243-ways ones, which means they are based on a dramatically distinctive principle as compared to slots with paylines. In a normal slot, paylines are kind of paths along which symbols should match up for a player to receive a cash prize. In 243-way slots, a number of matching icons may fall on neighboring columns but not necessarily so in some preset formations; the main thing is that they should be on adjacent columns.

Bonus features in online slots

Harvesting combinations of symbols all the time and getting wins is sure a good thing. But bonus features add tons of fun to the gameplay that may become a routine for some players. The most simple and frequent types of features are wilds and scatters. They are built into almost every game and add a touch of diversity. Wild symbols actually serve as mere substitutes, much like joker cards in some table games. Wilds often come with multipliers, meaning they will increase the ultimate payout for a certain combination they are involved in. Cogitating over new applications of a wild symbol, many real online slot providers come up with Expanding Wilds, Sticky Wilds and dozens of other versions of the idea of substitution peculiar to the wild symbol.

Free spins are another fabulous feature that many real-money online slots tend to be equipped with. They are exactly what they sound like: Free Spins. They come at no expense and are activated upon a certain condition being fulfilled, for example, when three or more scatters appear on the screen. A slot normally awards around 10 free spins or so. Some real money slots allow for selecting a bonus mode: 10 free spins at a multiplier of x2, 15 free spins with no multiplier, etc. (figures may vary). This selection feature lets the player reduce or increase the risk factor and variance during free spins.

The best slot makers have dozens of bonus features in their game collections, like: Progressive Multipliers, Pick Me Rounds, Avalanche, Bonus Buy, Cascading Wins, etc. These mix inside one slot to deliver unique experience. And this is especially true for leading providers reviewed shortly in the next paragraph.

The best real money slot providers for USA players

Players of the US prefer slots from:

  • RTG. A very popular game provider that focuses primarily on the US market. Their slots online have many local progressive jackpots. The RTG game collection is not that high as they have around 120 slots, nearly all of which being five-reelers. The best online slots from that vendor are allegedly Bubble Bubble 2, Naughty Or Nice and Rudolph's Revenge
  • Rival. Another US-friendly company online since 2006. Worth notice are their i-Slots, a unique, proprietary class of slots with non-linear gambling process and multi-staged bonuses. They also have a sizeable suite of classic slots
  • Betsoft. Some believe this is a top company operating in the gambling software sector. In fact, it has contributed largely to shaping video slots as we know it today. The total catalog (as well as mobile games) features over 200 titles with rich and vibrant 3D imagery, numerous bonuses and high payouts.

Play slots online: Instant vs Download format

Some of USA friendly most popular companies, particularly Rival and RTG, offer the dual option of instant play and downloadable versions. There are three clear benefits when you download software:

  1. A little more games because providers usually add fresh slots to the software first. Besides, some very old slots, developed at the early years, are found only inside the software, not in the instant play version
  2. Very low internet traffic consumed. Sure, for most players this is not a problem but for regions with poor wireless coverage, the casino software is a perfect way out
  3. In some casinos, tournaments are only available to join for players who use software.

Actually, this is more like a matter of habit which format of play is preferable. There are no major distinctions between both to affect the casino experience in a dramatic way. Finally note that the download version is for desktop devices only.
