How to choose the best online slot to play?

Once a certain online casino is judged to be the best available, the choice of slots becomes the next step in making a profit from the game. Remember, the chances of winning are, on average, around 90%.

By evaluating all the casinos available and then choosing the best possible one, you have already improved your chances of winning – perhaps by a few percentage points. No matter your gambling goals, first, you need to consider the slots that will most likely improve your winning odds even more.

Below are some important points to consider when choosing the best online slot.

  1. Check the provider and provider slot reviews
    Some providers certainly have a better reputation than others for creating unique and satisfying online slots. You’ll know what to expect from their games by getting to know them better. Moreover, individual slot reviews can provide detailed information about the slot’s features and winning potential. On our site, you will find hundreds of reviews of all slots, hot hits, and old classics!
  2. Find slots with a good bonus round
    If you run many free spins with additional features such as wilds, multipliers or bonus payouts, you can compensate for the losses you have incurred on previous unwinnable spins. Some players say it is a good time to end the game after winning the bonus round, especially if you achieve a higher starting balance than expected.
  3. Don’t just aim for the maximum win
    Some slots will be tied to a huge jackpot, but they tend to offset this huge winning potential by awarding very low payouts during the base game or through a bonus game that is simply too hard to run. To ensure your balance, look for slots with a good hit rate and the potential to cash out decent amounts, even during the base game.
  4. Pick a volatility game that suits your budget
    Another important factor to consider is game volatility or variance, which are different terms that describe the level of risk involved in a game. Low-volatility online slots are better for beginners with tighter budgets, while high-volatility slots are riskier but can help you win a lot. The maximum amount you can win in the game is also crucial, as the idea is to risk money for decent returns.

Top-rated slots by categories

We know many of my readers trust my reviews and guides a lot and don’t want to spend their time reading lengthy studies. So, we have collected below the best slot games we played and tested, broken down by category. Please choose the one you like and try it!

1. Online slots that pay out the most

Do you want to win a lot? First, you need to know which slot can pay out often and which is high. Knowing the Return to Player (RTP) in a game can drastically increase your chances of winning.

RTP (Return to Player) is a theoretical and real mathematical measure of the amount of money that each slot game should actually pay back over time. Simply put, if the house edge is 5% then the RTP is 95%. On average, after thousands of spins, 0.95 zlotys from each $1 turned by the slot will be returned to the players, and 0.05 zlotys will leave the casino.

This means you have a better chance of getting extra wins by choosing the slots with the highest RTP.

# Online Slot Software Provider RTP
1 Jackpot Jester NextGen 99,90 %
2 Ocean Princess Playtech 99,07 %
3 Ugga Bugga Playtech 99,07 %
4 Mega Joker NetEnt 99,00 %
5 Pixies of the Forest IGT 98,83 %
6 Barbarian Furry No Limit City 96,06 %
7 Action Bank Barcrest 95,16 %

2. Best bonus buy slots

One of the best features of online slots is their bonus round. What does it mean? When you hit some combination of symbols (unique to each slot), you can get a bonus game that rewards you with free spins and multipliers that drastically increase your chances of winning big. Usually, a lot of really big wins are obtained in such bonus games.

# Online slot Bonus feature
1 The Dog House up to 27 free spins
2 Sweet Bonanza 10 free spins + random multipliers up to 100x
3 Lovely Lady 25 free spins + constant x3 multiplier
4 Money Train 2 Random multipliers up to 100x and specific bonus symbols
5 Fat Santa Extension symbols

3. Best-paying jackpot slots

Every player dreams of this huge jackpot. You can win it using the online casino 2024 – even when you play slots.

Some players think that only roulette or a card game like poker can give you big wins. But it’s not like that. Plenty of slots can bring you a jackpot, and even a progressive jackpot increases every time players spin a slot, but the jackpot is not won.

# Online jackpot slot Biggest Jackpot Paid
1 Mega Moolah by Microgaming $ 10 242 133
2  Mega Fortune from NetEnt $ 9 160 385
3 Arabian Nights from NetEnt $ 8 272 792
4 Beach Life by Playtech $ 7 546 497
5 Funky Fruits by Playtech $ 6 590 409

4. Best mobile online slots games

Do you like betting on the go? Most online casino players gamble on mobile devices, not computers. Therefore, online casinos and slots are increasingly being adapted to smaller screens. We think a casino doesn’t need a dedicated app, but a well-designed mobile version is necessary. In short, make sure the mobile and desktop versions of the online casino look similar, and check for any hangs or crashes that could ruin your gameplay.

# Mobile slot Software Provider
1 Age of the Gods Playtech
2 Ghost of Dead Play’n GO
3 Starburst XXXtreme NetEnt
4 Fruit Party 2 Pragmatic Play
5 Gates of Olymp Pragmatic Play

What is the difference between playing slots for money and for free?

There are different ways to play online slots. You can either play for money or just try out the game for fun, meaning you don’t have to invest your own money to bask. Here, we will go through how you can take on slots online and how you can get started.

Advantages of playing online slots with money

Although you can try playing slots online for free, there are some advantages to playing with real money. On the one hand, there is an extra spice of excitement when you have bet money, but you can also take part in bonuses that you cannot use when you play free slot games online. It is also the case that you have to bet money to be able to win big!

However, the most important thing is that you have a gaming budget to stick to. It would be best not to play for more than you can afford to lose, and playing responsibly is a golden rule when you start playing online slots.

Advantages of playing slots online for free

We recommend you try playing an online slot for free before betting money. If you start playing for free, you can test the slot machine in peace before you risk losing your own money. You also gain experience and can see if you can use any strategy in the slot game.

One disadvantage is that you also don’t win anything when you don’t invest your own money in slot games online.
