Where does the rest €2.5 go? Well, that is casino’s profit. Therefore, an online casino owner wants his players to choose low-RTP slots, while users conversely wish to bet in high-RTP machines. Now, that’s some Hegel’s clash of opposing forces! To sum up: casino owners are interested in promoting slots which give them maximum profit. And they do it successfully, including those slots in various bonus programs, free spins, no deposit bonuses etc.
After a few seconds, the virtual reels stop and, if there is a win, the software awards a prize. So, how are wins defined? There are a certain amount of paylines in every slot (usually 10-50), and you can view their pattern in a rules section. A payline may be strictly horizontal or broken, and it goes through all 5 reels. If there are 2 or 3 same symbols on a line, starting from the leftmost reel, a player is rewarded coins according to a paytable. In most cases, after a spin, a player gets less money than he bets. This is called a ‘False Win’. For example, you bet €0.20 and get 3 cherries on a payline which award you €0.05. Did you win? Yes. Is there a profit? No. But due to human psychology, a player does not perceive this ‘win’ as a loss since he still sees some funds being added to his balance.
Spinning columns are called reels. When it comes to the number of reels, slots may be classic (3-reel) and modern (5-reel). In general, most players prefer 5-reel slots since they are colorful, spectacular, bright, have more animations, bonuses and special symbols. They are simply more interesting than good old classics.
3-reel games have 1, 3 or 5 paylines and small bet limits (usually not higher than €0.20). They rarely have Wilds or Scatters and almost never have bonus games. These solutions generally attract retro-style lovers and players of older age. 5-reel slots are way more complex: on a big playing field of 15 or 20 symbols, there is a lot of room for creativeness. They can be equipped with bonuses of different levels of complexity, several kinds of Wild symbols, captivating 3D graphics and cutscenes.
Slots themes: this is pretty simple. Slots are commonly dedicated to Ancient Egypt, mythology, celebrities etc., and their themes are expressed solely through game symbols (for instance, in a game themed on Marvel universe there obviously will be icons with various superheros). Some developers (for example, Microgaming in their early days) do not bother at all and use the same engine and the same paytable, just replacing game symbols. In the end, we have 2 identical in terms of mechanics games with, however, different sets of icons.
Volatility can be low, medium and high. Low volatility games pay almost every spin, but the prizes are not really impressive. And contrariwise, high volatility games offer you a chance for a huge win, but winning combinations in those slots are pretty rare.
This parameter is sketchy, but some developers still specify it in their gaming products. Experienced players often pay attention to volatility and choose slots which suit their playstyle (“I want to win often even if the prizes will be low” or “I am okay with not winning for 20 spins and then getting a big win”).
Bet limits. A slot machine usually has 1-3 adjustable parameters relevant to bet size: number of paylines, bet amount on one line and coin size. By changing these parameters, a player changes his bet on a single spin: from a few cents to dozens and hundreds of dollars. As a casino owner, you should offer slot games with flexible limits, since gamblers who spend large amounts of money, so-called high-rollers, love to wager a lot.
In case of ‘local jackpots’, which are comprised of bets made by players at a specific casino, an operator has to pay it. But it’s safe to say that by that point a slot will have already earned you more.
If a jackpot is won in your casino, it is a great advertisement, since all gambling websites and forums will noise abroad the news, which will promote your platform without you spending a dime. That’s why we recommend you to additionally order progressive slots package. You will not regret it.
