Best Online Slot Machines 2023

When looking for decent slots, the first thing that comes to mind is checking the return to a player rate. It would be a good idea as it represents the casino’s generosity and increases the chance of winning big. Yet, several more aspects are also worth your attention. For instance, experienced gamblers consider volatility, gameplay and payouts, free spins, and bonus rounds.

We’ve written this review to help newbies get acquainted with the essential factors and select the best slot machines to play this year. You’ll learn about different slot offers and find out what are the top 10 slot machines with high payouts in 2023.


🔍 How to Choose a Slot Machine?

To find entertaining online casino slots with the highest payout rates, you need to follow certain guidelines. The most crucial thing is to pay attention to the machine’s characteristics. Variance and Return to Player Rate play a vital role in determining the amounts you win.

What is RTP?

Newbies always wonder what the RTP rate is and why it’s an essential part of online casino games evaluation. Well, this number shows the average amount that the slot machine will pay back to a gambler over a certain period. Usually, such figures are displayed as a percentage rate and considered a mathematical profit of online casino slots.

To clarify the way it works, let’s review the well-known game Gonzo’s Quest from a famous NetEnt provider. The payback to a player equals 95.97%, which means that for each $100 you spend, you’ll receive $95.97 back. Yet, keep in mind that the scheme is based on thousands of rounds and spins. So, don’t expect to get such a sum each time you make a wager. Moreover, there is always a possibility that you’ll either get golden or stay with nothing.

What is Volatility?

The volatility of the online slot machines represents the frequency and the size of the winning amount. It usually ranges from low to high. On average, slot games offer medium-high volatility, but still, the figures vary depending on the casino. The less volatile a slot is, the more often you’ll trigger the wins, but payouts will be smaller. The higher it is, the less often you’ll get the reward, but in bigger sums.

Let’s say you wager $1 for a spin round with a high volatility game. You can play over a hundred times but win nothing. Then hit a hot streak and boost your bankroll up to $300. Yet, by depositing $100 with low volatility slot games, you can place $5 bets and regularly receive profits from $1 to $10.
