How to Choose the Best New Slot Games

Choosing the best new casino slot games needs more than you guessing when a slot game will hit – it's a decision that comes with the right combination of mobile compatibility, RTP and volatility, as well as potential and slot-based casino bonuses.

Mobile Compatibility

It can be quite uncomfortable if you have to sit down at your PC every time you want to play casino games. This is why you should ensure that you can play a new online slot game on your preferred device at mobile casinos, giving you convenient and lag-free mobile playing sessions on the go.

Theme, Graphics and Soundtrack

You should find the right aesthetic that suits you with regards to the theme, graphics and sound effects. It’s important to be careful with your theme choice, though. This is because branded slots and TV slots, for example, have low RTPs. However, you can still win big on low RTP slots – it just all depends on luck.

Bonus Promotions for New Online Slots

In addition to being one of the most important casino features in general, good bonuses and promotions can also help you beat the house edge with new slots.

In fact, some new slot games even have specialised casino bonuses that come with their release, most often free spins. However, you should always read the wagering requirements properly to make sure you know what you’re signing up for.

RTP and Volatility

The RTP and the volatility of new casino slot games tell you how much you can expect in the long run and the size and frequency of wins, respectively. High RTP slots tend to have 97% or higher return to player, which makes the above-mentioned Book of 99 a great choice.

As a general rule, the lower the RTP, the higher the house edge; since statistically less money is being returned to players, it’s important to see how this can affect your gaming over time.

Additionally, be sure to note the volatility of any new slot games you play as well, and choose according to what you prefer – little and frequent payouts (low volatility) or large and sporadic payouts (high volatility).

Special In-Game Bonus Features

A lot of slots have their own form of “bonuses”. This involves wilds, scatter, cascading reels, etc. These are great for new slot games gambling because they can directly increase the frequency and/or limit of the wins you can get on these games.

For example, Wilds will substitute for non-winning symbols in order to create a payout, whereas Scatters will give you free spins or bonus games to further your chances of winnings.

Top New Slots Software Providers

This is probably the most important to look out for. A reputable software provider means a licensed, fair game with great in-game features, device compatibility and even release bonus offers sometimes.

Some of the major names in the industry include the aforementioned NetEnt, Pragmatic Play and Big Time Gaming, as well as Play’n GO and Yggdrasil.

Jackpot or No Jackpot?

Some slots have multiple jackpots that accumulate progressively over time. Jackpot slots provide an opportunity to cash out massively; however, they are difficult to get.

So it's wise to choose a jackpot slot with a rewarding base game. This is important because while you can look forward to a slot with a great jackpot, the odds of winning major prizes are still rather low.

Therefore, you should look for a new jackpot slot that gives you a perfect cocktail of paying out well while keeping you entertained for hours. Take a look at our guide to progressive jackpots slots to find your favourite!

 

How to Win at New Slot Games

You should know that winning is not guaranteed with new slot games gambling or any other kind of gambling. But here are some tips that can help you have a great time playing games, and a chance at beating the house edge.

  • Select the right casino with a valid license, generous bonus offers, convenient banking methods and reliable customer support.
  • You should set aside a fair sum for your bankroll that will give you enough playing time. However, this is not a call to gamble irresponsibly – think of your bankroll as an investment.
  • Based on your bankroll and the slot’s paytable, volatility and its RTP, you should develop a solid slot strategy for how much you will bet on each spin.
  • Cash out any winnings regularly, so that you don't end up chasing losses or stretching yourself too thin.
  • Practise playing new free slot games in the demo mode at free play casinos. This is always a useful activity, since it helps you understand the payout frequency first-hand, without risking any real money.

 

New Slot Games Conclusion

So consult our top lists to find new online slots with great in-game features, plenty of entertainment value, high RTP and real money prizes. Then, once you’ve found one that catches your attention, choose your favourite from our recommended new slot casinos to start playing today!
