SlotCatalog's Slot Game Ranking
As previously mentioned SlotCatalog’s ranking describes slot game exposure in online casinos, by region. Simply explained we crawl over thousand online casinos daily to see what games they expose the most. During each casino crawl we go through all the online slots that you can play in the casino. Each online slot will get an average lobby position score. This means that:
• Higher placement in the lobby will give a stronger score.
• If a game is absent in a casino lobby we will give it the maximum lobby position.
• Larger online casinos have more weight than smaller ones. The weight is calculated by the geographical strength of the online casino compared to other online casinos in the same region).
This means that our ranking method is based on an average score / lobby position for each slot game. A lower average means a better, more exposed game.
Our SlotRank metric is based on all online slots average lobby position scores, but in relative terms. This means that the game with the lowest average lobby position will get SlotRank #1. The game with the second lowest avg score will get SlotRank #2 etc.
As new games are released daily we update our ranking each day. This way we make sure that you as a player will have the latest ranking available, including the 0-day releases.
What is a slot machine?
Online slots is a term that covers a vast and diverse array of features, themes and setups, and it’s also a field that is in constant development. One thing all slots have in common is that they require no real skill to play. As long as you’re able to press the spin button, you’re basically good to go.
Slot machines (both physical and online) are operated by a Random Number Generator (RNG) that’s been certified by third party agencies for fairness and functionality. The theoretical payout potential - usually called Return to Player (RTP) - can vary significantly from game to game online, but the industry average hovers around 96%. This means that the average House edge for online slots is around 4%, and thus significantly lower than most physical slot machines.
Another thing that varies a lot for online slots is something called volatility (or variance). Even though the RTP can be very similar (or even the same) for 2 slot machines, you’ll find that some games pay out seldom but big, while others pay out smaller wins almost all the time. There is also a middle way here, and it’s up to each player to decide what they prefer.
Generic Slot features
There’s almost no end to the creativity of game providers when it comes to slot features. Still, some basic features tend to be included in almost every online slot out there. Here we shall briefly explain these generic slot features for you.
Tells you everything you need to know about winning symbols, and the payout for each combination.
Bet Limit and Paylines
All slots have a minimum and a maximum limit for how much you can bet, but this limit can vary somewhat between each game. Usually, the limits are both low and high enough to suit most players, though.
The number of paylines will vary between 1 and all the way up to several hundred thousand (in rare cases). Usually there will be between 1 and 100 paylines (or ways to win as it’s sometimes called), but there are many exceptions out there too.
Wilds, Scatters and Multipliers
Almost all online slots come with a wild symbol and a scatter symbol. The wild symbol will act as any symbol (except the scatter) to maximize your winnings. The wild can come in many forms and combinations, including stacked wilds and sticky wilds (which are the most common).
A certain number of scatters (normally at least 3) randomly spread across the reels will trigger the free spins feature on most slots. A multiplier will boost your winnings by a factor of at least 2x, and can sometimes be combined with wilds.
Free spins and bonus games
The number of free spins you get will usually be tied to how many scatters you land, and sometimes you can get additional free spins by landing more scatters. Many slots also come with bonus games that can take many forms. However, some sort of click-and-pick game is common.
Video slots are by far the most common type of slot machines you’ll find online. They have at least 5 reels (sometimes more), and are characterized by sophisticated graphics, sound effects and sometimes 3D intros of almost cinematic quality. There are simpler video slots also, but usually they come packed with innovative bonus features and exciting special effects.
Classic slots have 3 reels, and they are usually a lot simpler in all possible ways than the video slots. Many times classic slots will resemble - or be exact replicas - of physical fruit machines or one-armed bandits. They have a nostalgic appeal for many, but some also just prefer the simplicity the Classic slots offer.
