Slots are among the most popular casino games. Due to a high number of game studios, new slot machines are launched every single day. This makes it difficult to find the best slot machines, but with our slot guide, you can find the best online slots.
One Armed Bandits & Slots
Liberty Bell is considered the first slot machine. The fruit machine or the one-armed bandit was created by Charles Fey in 1895. The slot machine became highly popular and sat the standard with its three reels and one line.
The three reels are still used on many new slot machines today, but it is more common to use five reels with three or four rows and several lines.
The new slots are also inspired in other ways by the old one-armed bandits. Lots of new slot machines have play cards as symbols.
Symbols, Reels & Lines
Today, many of the visible mechanics are the same. The slot machines have reels, symbols, and lines. But, over the years, these have developed, so today you can find slots with three, four, five, and even six reels. The number of positions on each reel also differs. You can find slots with three, four, five, or even more. When it comes to lines, it is normal that the slots have between 10 and 50 lines.
Some slots, like the new Wild Chase Tokyo Go, does not have lines. This slot has Ways to Win instead. As you can see from the picture, the number of positions on the reels varies from three to five. We will explain how this works later. But first, you will need to know the basics of coins.
Slot Coins, Coin Value & Bet Levels
There are a lot of slots where you can choose to wager €0.1 or even €100 bets. But, some slot machines have coins instead of just a normal currency. That especially applies to NetEnt slots. When you start playing at these slots, you can see one option where you can choose the bet level. That works as a multiplier on your bet. You can choose any level from 1 to 10. Then you have coin value. Here you also have several options to chose from.
To calculate the value of each spin with a given bet level and coin value, you have to multiply bet value, number of lines, and the coin value. All this might sound complicated, but there are some advantages by doing it this way. A lot of the prizes you can win on a slot is calculated by a multiplier, rather than just a number of euro. Then it is much easier to find the slots where you can win the biggest prizes.
It is normal to use card types like spades, clubs, diamonds, and hearts, or face cards like 10, Jack, Queen, King, and Ace for the lower value symbols. Then, you have the high-value symbols that are often symbolized with characters from the slot theme. Finally, you have the special symbols, Wilds and Scatters.
The function of these symbols is depending on what slot you find them on. But, as a thumb of rule, Wilds can substitute for other symbols, while the Scatters can activate a bonus game or in-game free spins.
Ways To Win
We mentioned that the new casino game, Wild Chase Tokyo Go, did not have any lines. Instead, it has Ways to Win. To understand the difference between lines and Ways to Win, we will first explain how you win on classic slots with lines.
To win a prize on a classic slot with lines, you have to land three or more symbols of one kind on one active line on adjacent reels from left to right. If you get three or more symbols of one kind on adjacent reels from left to right, but not on one active line, you will not get any prize.
But, when playing on a slot with Ways to Win instead of lines, there are no lines to land the symbols. That means that you have to land symbols of one kind on adjacent reels from left to right.
Win Both Ways
Usually, you have to collect symbols of one kind on adjacent reels from left to right to win. But, there are some slots where you can win both ways. Starburst is one of the most popular slots with this feature. On this slot, you can land a winning symbol combination from both left to right and right to left.
If you get a symbol combination covering a complete line, you will only get one prize, not for both ways.
With new slots being launched close to every single day of the week, the diversity of online slots is huge. For new players, it can be difficult to find slot machines that they will enjoy. Because of this, it is important to know a bit more than just the basics we just covered.
It is no doubt that design is important. But, just as important are the slot features and the hidden slot mechanics. By knowing slot features and statistical measures like Return To Player and variance, it will be easier to find online slots that you will enjoy.
Just a few years ago, mobile gaming was something that belonged to the future. But, today, it is mobile first. The development of both casino games and mobile phones has played big roles in this. Now, a new online slot will also be available for mobile gaming. The new slot will also be exactly the same on mobile and online. This was not the case a while back. Then we had one mobile version and one online version of the slot.
New Online Slots
We mentioned that Liberty Bell only had three reels and one line. This is also the case for the legendary Bell of Fortune slot by Play’n Go. There are several other as well, like the Jackpot6000 and Mega Joker by NetEnt.
The classic slot machines are recognized by their simple design and few slot features. For many players, these are the best online slots as they give a very clean gaming experience.
The power of mobile phones and laptops allow game designers to be more creative. It is also possible to add interactive elements like bonus games and videos making the game coming to life. Today, most new slots are video slot machines as these are very popular. Some of the most famous video slot machines are Blood Suckers, Starburst, Gonzo’s Quest, Wild Chase, and the Jackpot Jester series.
Progressive slot machines are worth knowing if you consider visiting some of the PayNPlay casinos. These slots have a top prize that grows for each stake the players are wagering, hence the name, progressive slots.
For each bet made on these slots, a certain percentage will be added to the jackpot until one lucky player takes it all. Often, the jackpot contribution is between 2 – 5 % of the bets wagered at the slot.
There are two different kinds of progressive jackpots. These are the shared jackpots and the local jackpots. There is also a very important sub-category, the Must Drop Jackpot or Daily Jackpot.
If you log in to two different casinos, like Hajper Mobile and the new Kassu Casino, you will notice that the jackpots on Mega Moolah, Mega Fortune, and all the other slots with a shared jackpot will have the same value. The reason for this is that the jackpot is shared. It is the same jackpot on both casinos, and any other casino offering these games.
From every single wager made on the slot, a given percentage is added to the jackpot, regardless of what casino the game is being played on. Of course, the shared jackpots are the biggest, and often you can see slots like Mega Moolah and Mega Fortune having a jackpot worth more than €10,000,000.
Local jackpots are the complete opposite of the shared jackpot slots. On the local jackpot slots, only the wager on one casino will contribute to the jackpot. So, if you visit Simppeli and TurboVegas Mobile, you will notice that the value of the jackpot on Divine Fortune or any other local jackpot game is not the same. In other words, there is one Simppeli jackpot and another TurboVegas jackpot.
Must Drop Jackpots & Daily Jackpots
Red Tiger is one of the smaller game studios. The company launched in 2014, but already they have made a name for themselves. The reason for this is the Must Drop Jackpots or the Daily Jackpots. Both are progressive jackpots, but they do not get as big as the Mega Moolah jackpot. This is because they have to drop before they reach a certain value or within a given time. With a timer counting down to when the jackpot has to be paid out at the latest, these slots can give you thrilling gaming experiences.
Random Number Generator
Every single game round on an online slot is completely random. The way this is done is by using a Pseudo Random Number Generator. These are creating several hundreds of sequences of simulated random numbers every second. Each sequence is a game round. When you press the play button on a slot, the most recent sequence will be attached to your game round and determine the outcome of it.
The casinos can not alter the RNG, and the gaming licensors are frequently checking the RNGs that can be found at the gaming providers to prevent cheating and fraud.
Return To Player & Variance
Even if every single game round is random, there are a few things that can be done to lower the casinos’ edge when you play slots. To do this, you have to know something about Return To Player, or RTP for short. RTP is a statistical measure that says something about how much of the stakes wagered on the slot that will be paid out as winnings in the long run. The higher the RTP is, the better is the slot, as a 98 % RTP slot will pay out more than a 95 % RTP slot. You can find the best high RTP slots here.
Variance is a less known statistical measure. But, it is no less important. Variance says something about the expected deviance from the RTP. In other words, a low variance slot is likely to give you a return close to RTP, while a high variance slot is likely to give you a return that is highly deviant of the RTP. To put it another way, variance says a lot about the risk. When playing a low variance slot, you can expect a lot of smaller wins, while the high variance slot is likely to take all your money or give you that big win.

How To Decide Bet Size
Deciding how much you should put at stake is difficult. It depends on how much money you have to spend on the casino, what game you are playing, if there are any cash drops or other promotions, and what you are aiming for. It is important to know how many spins you can do per minute. Usually, it is possible to make somewhere around 5 to 10 spins. Then you should think about how long you want to play. We mentioned the RTP and variance, baking this into the formula, you can expect to lose 5 % of your bankroll each time you have wagered the total value of it. (If playing a low variance slot with 95 % RTP.)
Let us say that you make a €100 deposit, and want to play on a low variance slot with a 95 % RTP. If you wager €1 bets, you are likely to have €95 left after 100 game rounds or approximately 14 minutes if you play 7 game rounds per minute. The next time you wager your bankroll, now worth €95, you are likely to have €90.25 left after 95 game rounds or 13 game rounds with a pace of 7 game rounds per minute.
If you rather made €5 bets on the same slot, you could expect to have somewhere around €95 after only 20 game rounds or 3 minutes. This would give you the impression that the slot is eating your money, and we think it would not be a nice gaming experience.
In our first example we wagered 1 % of our bankroll per spin, while in the second example, we wagered 5 % of the bankroll per spin. It does not seem like a big difference, but, wagering 1 % can likely give you hours of entertainment while wagering 5 % you could end up with an empty player account within one hour.
Are there any slot strategies that work? No, at least if you want a slot strategy that will make you rich. The casino has the edge, no matter what you do. But, if you learned a bit about RTP, variance, and slot features, you can use a slot strategy aiming to give you as much entertainment as possible.
Yes, online slots are using a device called Random Number Generator. The device ensures that every single game round is random and can not be predicted.
It is important to know that the casino has an edge over the player. Online gambling should only be considered entertainment and not a way to earn money.
Mega Moolah has the world record. In 2015 this slot paid out a progressive jackpot worth more than €17.800.000.
Free slot play can be different things. You can get a no deposit bonus or no deposit free spins. You can also try online slots for free using play money.
A loose slot is a slot that is paying more than it should according to the theoretical Return To Player. A slot can be loose because of the variance. The opposite is a tight slot that is paying less than the theoretical RTP.
It is important to check the Return To Player and variance before you start playing. You want the RTP to be as high as possible. If you want to play on a high-risk slot where you can lose it all or bag the big win, you should find a high variance slot with a high RTP.
There are several ways to win at casino slots. You can land a winning combination of symbols or activate a bonus game. Some slots also have Mystery Wins that can be won like a cash drop.
Mega Joker by NetEnt has an RTP of up to 99.00 %. Jackpot6000 by NetEnt has an RTP of up to 98.90 %. 1429 Uncharted Seas by Thunderkick has an RTP of 98.60 %. You can check out our complete Top 10 High RTP Slots list for more information.
