Online Casino 101: A Comprehensive Guide

Updated: May 21, 2021 10:11

Online slots (online pokies) is an online gambling application that produces a set of random numbers visualized as symbols across several reels (3 or 5 reels slots). The way that a software manufacturer connects similar symbols to count towards your winnings is called a payline.

All slots are hosted and ran from the manufacturers servers, online casinos are being only providers of access to them, i.e. intermediaries in fact. So, whenever you play online slots for free or in an online casino for real money you actually play it on the slots manufacturer’s premises, online casino only takes and pays back your money. Online casino cannot change the gameplay or distribution of winnings in any specific slot.

Slots manufacturers are audited by such organizations as eCogra, etc to produce a fixed return on a players money over a large number of spins (usually, millions of spins). This theoretical value of online slot to a player is called Return to GOer (RTP). For example, The Highest Payout online slots by NetEnt are:

  • Jackpot 6000
  • Dead or Alive / Dead or Alive 2
  • Reel steal
  • Wild rockets
  • Jungle Spirit Call of the Wild
  • Wild turkey
  • Secrets of Christmas
  • Secrets of the Stones

As you can see the payout is negative (less than 100%), so a player may think he/she would lose on average about 5 cents from every dollar each time he/she spins the slots. Yet, the idea of RTP is different: you will be losing your 5 cents in the long haul, yet, till that time you may win (go green) and lose (go red) a number of times, and you don’t exactly when it happens. How to predict when you will win on a slot machine?

To do that, it’s important to understand how online slots actually work. Let’s take the example of NetEnt slots: they use the Pyramid principle, which means that all players form a prize pool from the money they have lost. In theory, if you are the only player who plays in a wholly new online casino a specific slot, the prize pool is empty and is only filled up off your money. So, you will be losing all the time till you fed up the prize pool and it will start to pay you back your own money. In this case, you will get back 90-95% of the amount of your deposit. This is what RTP really is.

Now, NetEnt manufacturer takes about 2-5% of the prize pool to themselves and distributes the rest of the money pool (RTP) to all players that have come to play this game. There are different levels of distribution of the prize pool: by casino, by the online slots game, by the wager value.

Prize pool is distributed separately by each single online casino, so could only potentially get the prize pool formed by players who lost they money in the casino that you play. The same concerns a specific online slots: you may only win what others have lost on a specific online slot that you play.

Wager value or the size of your bet is how actively you contribute to the forming of the prize pool. There are 4 levels of online slots players by the contribution to the prize pool:

  1. Low bets players (usually making $0.1 to $5 bets)
  2. Bonus hunters (usually making $5 to $10 bets, i.e. betting towards the max wager limits when playing with bonus money)
  3. Medium bets players ($10 to $50 bets)
  4. High rollers ($50 to max allowed bet)

At any level (except for the High Rollers) from 1% to 10% of the accumulated prize pool go to the higher stakes’ prize pool for the big winning. Likewise, Low bets players would have a portion of the prize pool they formed passed onto the next level, i.e. Bonus hunters. The same concerns those making $5 to $10 bets. Since the game is underway between players and an online casino would only takes it’s small part, players essentially compete with each other for the prize pool: the more players at each level, the less chance to win big.

Obviously, the medium value of bets ($10 to $50 bets) is the most profitable wagering limit for hitting a big win. At these limits, there are much fewer players than above, but here are collecting money from previous limits (the bets from $0.25 to $10), and are much less participant in the "drawing" as put it.

Software providers must disclose the odds of winning on specific slots and these data form dependencies. They disclose the maximum win, probabilities of hitting any winnings (and how they distributed towards normal play and bonus play mode) as well as probabilities of hitting two wins in a row. This values forms the following dependencies:

  • The Higher the max win, the longer a cycle of winning, i.e. when a slot machine starts to pay back big.
  • The higher the Volatility (also called Variance or Dispersion) of Winnings, the less predicted is the size and frequency of winnings at the end of the cycle.

In potentially ‘big win’ slots, you can wait many rounds till you get any winnings (have lots of empty spins). Therefore, less people would play it and the cycle of winning does depend on the prize pool too.

Slot Games Definitions

Paylines:  Paylines run across the slot screens as well across all reels in a horizontal, diagonal or zigzag pattern. A payline gets activated as you bet on it. When a composition of symbols forming the winning symbols emerges on an activated payline, you win that game and the payouts coming with it.

Reels, which are an essential feature of any slot machine, are wheels that have printed symbols. On pressing the ‘spin’ button, the reels start moving and come to a stop finally. It is the positioning of symbols on wheels that determines a winning combination. The symbols that a slot game may contain conform to the game itself. For instance, the Beach Life Progressive Slot by GOtech with a beach-theme comes with beach-themed symbols.

Multiplier: Generally, the Wild symbol is the multiplier. True to its name, it multiplies. So, in case a winning combination contains the multiplier, your payout gets multiplied by two, three or even more times.

Wild Symbol: You’ll find these on online as well classic slots. They can replace any symbol but not the scatter symbol for making a winning combination.

Scatter Symbols:  called so because they may be scattered everywhere on the reels and can make you win. Usually, a player is required to have two or more scatters on two or more paylines for winning that round. Before you start placing bets on slot games, you need to decide the coin size you would like playing and the number of paylines you would like to be activated.

Selection of coin size is done by pressing the (+) button for increasing the coin denomination or the minus (-) button if you want to play with a lower denomination. The number of playlines you want to activate is done by clicking on ’select lines.’ And, this is how you can calculate the total amount of your bet. Suppose you choose a coin value of $0.25, with 3 paylines along with 5 coins. So, the total amount of your bet would be 0.25X3X5=$ 3.75 Online slots are provided with a payout plan, which tells you how much you’ll get paid on winning various combinations. So, you don’t have to use your calculator as the needed information is instantly provided by all slot games. Here’s an introduction to various types of pokie machines.

Types of Online Slots

Classic Slots

When you like playing traditional online casino game, especially like old fashioned lot machine, you would find the Classic Slot Machines fulfilling your requirements. First online edition of these games was developed by Microgaming during 1994.

Fruit Fiesta (or recent re-incarnation Happy Fruits) and Cash Splash are among the oldest online slot games. Initially, they were coming in three reel edition but now you get five reels editions too. These are quite easy to play, compared with other complex slots as generally they generally lack unusual symbols like Bonus Symbols, Scatter Symbols and Wild Symbols. Other leading companies like GOtech and Cryptologic too have developed Classic Slots.

Rags to Riches from Cryptologic is among popular Classic Slots that is connected to a progressive jackpot too. Tomb of the Pharaoh, a Classic Slot from GOtech with the looks of a land based mechanical slot machine has all the real sounds that are heard in a land based casino. However, it doesn’t offer progressive jackpots.

Here are Classic pokies / slots details:

  • Number of reels: 3
  • Number of paylines: Varies from three to five
  • Wager: Can be one, two or three coins
  • Winning combination: A paying symbol must appear in reels of an activated payline to trigger winning. Usually, there is just one symbol that allows winning though it may appear on a single reel only.
  • Free spins: Generally, classic pokies don’t offer free spins or bonus games to some exceptions that you may find in Aristocrat pokies.
  • Software: Aristocrat, GOtech and Microgaming provide extraordinary classic pokies.

GO Video Pokie Games Online

The basic difference between classic pokies and online video pokies is that the latter comprise of five reels against three in case of classic pokies. However, there are many other differences too. Video pokies have more visual appeal. Current video pokies generally display wins via computer graphics to heighten the visual effect. Well known pokies based on popular TV shows or movies display animation by way of short video clips.

Generally, themes of such pokies include a sport, natural beauty or ancient civilization. The backgrounds of the wheels symbols accentuate the theme. These are identified by their bonus features, the most popular of which is the free spin feature. As this feature gets activated, you are allowed to play many spins for which you won’t have to place any bets. The other admired feature is the bonus game on a second screen. The most usual form of this fixture demands you to select items to award you with random bonus payouts. Here are some of the most admired video slots: South Park, Iron Man-3, Wipeout, Where’s the Gold, Fruit Stack, Magic Portals and Dragon Island etc.

In the past, jackpot pokies were individual games but the present trend is to connect different pokies to the same jackpot.
