Best Slots to Play with Free Spins Bonuses

If you plan to use casino bonuses and in particular free spins bonuses, it is worth knowing and understanding which slots will give you the best chance of winning real money. It is also important to understand how free spins bonuses work and how you can determine what the best slots are for your real money gaming. In this article, you'll discover the most popular slots used in free spins promos as well as how to choose the best slots to play when using a free spins bonus.

There are a number of things you need to be aware of when using a free spins casino bonus to play the best slots. The first is that you might be limited to the games you can use your bonus on. You will often be restricted to a handful of titles and sometimes just one or two specific slots. This means that you can't play any other games and quite often the titles chosen are not big money games. This does however mean that you can use your promo to learn how to play the games and trigger all the bonus features so when your bonus spins are over, you'll be able to play more effectively and maximize your winnings. Another thing to remember is that you will be limited to the amount you can bet and if you've claimed a no deposit code, there will be a limit on the amount of real money you can win. With that said, for slots fans, free spins are the best casino bonus to claim and you'll understand why by the end of this article.

How to Choose the Best Slots when Using Free Spins Bonuses

There are a number of factors to take into consideration when choosing which of the best casino slots to play for real money and these are explained below.

Volatility

One of the biggest factors when choosing which casino slots to play is the volatility. Volatility tells you how often the symbols change, the variance in their appearance, and how different each spin will be as you play. It essentially means, how regular the payouts will be and what their size is. You'll find low, medium, and high volatility slots. A lower volatility slot machine has fewer events that will change the spins and slots with high volatility will have a lot more changes occurring on the reels. You'll usually find volatility stated on the game's instructions and another way to tell is by looking at the payout table. If the difference between the amount you win for three of the same symbols or six of the same symbols is small, then the variance is probably low.

Players who want to play the best slots for entertainment purposes will find titles that have a lower volatility more appealing. These are games that allow you to spend little but have a large amount of spins. The payouts tend to be lower but more frequent. These slots are perfect if you like winning often but you may find that the maximum jackpot is limited to 1,000x your wager. With low variance slots you are more likely to win every three to four spins which means there is less risk. The downside is that you might have to play for a long time to win a large amount.

Medium variance slots are suited to players looking for bigger wins and excitement.

High volatility slots have much bigger payouts but the hit rate is quite low and it means you will have to spend a large amount in order to see a return in your investment. This style of slot tends to appeal to players who are after the big wins. These tend to be higher risk slots and can empty your bankroll quite quickly or net you a huge real money jackpot.

Return to Player (RTP)

The RTP percentage is the amount of money a player can expect to get back when playing the best slots over a period of time. The RTP can range from 90% up to 98% and the higher this is the better. Both variance and RTP should be looked at because the variance will tell you how frequent wins will be and how big.

Low Variance Slots and Casino Bonuses

Casino bonuses come with wagering requirements which means you have to wager a certain amount before you can cashout your winnings. The reason why a lot of new players tend to lose their winnings while using a bonus is that they play medium or high variance slots. If you play high variance slots and hit a losing streak it can be very easy to try to chase the free spins round to try and recoup and never get there. To stop this from happening it is recommended that you play high variance slots when you first get your bonus and then switch to low variance slots toward the end. Low variance slots can be great if you play high RTP titles and when you are playing with a promotion and don't want to risk your winnings. They may have smaller wins, but they make it easier to clear the wagering requirements.

Top 10 Slots with the Highest RTP

Most new casino players look for slots with the highest RTP when playing because these tend to offer the lowest risk over time. Below are the top 10 slots in terms of the highest RTP but we've also included the variance so you can decide if they are right for you.

  1. Avalon II - 97% RTP medium variance
  2. Guns 'n' Rose - 96.98% RTP with a low to medium variance

Best Slots to Play with Your Casino Bonus

Now that you understand RTP and volatility, it should be easier to select the best slots to play with a casino bonus. Low variance, high RTP slots will always be a better choice when clearing wagering requirements and there are some specific titles that you can choose, as well as specific software providers.

RTG's Asian games such as Ancient Gods, Dragon Princess, and God of Wealth are all low variance with high RTP percentages and a great choice.
