Pick the best online slot regardless of the software

Here you can find the best slots dissected to their essential elements and a short analysis of the software by different providers. You will need 3 minutes to read our article.

  • NetEnt software

The online slots by the industry leader - Company NetEnt, have RTP that reaches 99%. Regarding characteristics: you will see a few bonus features with winning 200x+ very rarely (excluding Netent online slots with high volatility).

  • Microgaming software 

The new slots show balanced RTP, but some titles still have a bad percentage among the old games. Therefore it is fair to say that averages between 88% and 98.6%. Most of the Microgaming pokies are with a long cycle and high volatility of winning. 

Summarizing till here: The Microgaming’s slots will give lucky bonus features with the winning of 200x+ and rarely 500+ more often than NetEnt.

  • NYX (Nextgen) software

The slots by NYX have higher volatility compared with the prior two producers. It is still not as high as the next developer - Novomatic, but bonus features show greater promise than the games from NetEnt and Microgaming. The RTP is in the range of 95-97%, which is a decent index for the slot industry, except for Jackpot Jester Wild Nudge - 98%.

  • Novomatic software

The slots from Novomatic exhibit high volatility and most of the bonus features deliver significant capacity for winning (500x+). On the other hand, the bonus features will be triggered rarely, and the slots will demonstrate more empty spins than the slots of the above three software developers. The average RTP level here is very low - 95%.

  • Yggdrasil software

Software by Yggdrasil appeals to the players with unusual bonus features in the slots that manifest high volatility. The RTP is standard 96-97%, except for the Jokerizer slot - 98%. 

  • PlayN Go software

Play'N Go company continues to expand very boldly in the last couple of years- launching monthly new online slots with high volatility (as Book of Dead or Reactoonz). The RTP is standard 94-97.6%.

NetEnt (Net Entertainment)

NetEnt’s slots are favourite to the majority of the online players for their stellar quality as well as for the huge chance to win life-changing prizes. With every new thrilling addition to their slot library, the developers provide a magnificent game that can answer all players’ demands.

The company adjusted its software guidelines, notably affecting the player's psychology, uplifting his gambling fascination. Inside NetEnt’s portfolio are detectable slots with short (for example, Evolution and Disco Spins) and very long cycles (for example, Jack and the Beanstalk and DOA). As a result, the returns’ volatility is high. Please view the full list of their RTP. 

Here are the top NetEnt slots by RTP and their attributes:

Some of NetEnt’s slots truly give the possibility for a positive mathematical expectation.

Mega Joker

Blood Suckers

  • The rate of return (RTP): 98%;
  • The cycle is fast;
  • The variance is low;
  • Play at the Blood Suckers for free without registration;

Kings of Chicago

  • The rate of return (RTP): 97.8%;
  • The cycle is average;
  • The dispersion is low;
  • This is a demo version of the Kings of Chicago slot;

As you can see, some of the Netent slots give the possibility of obtaining a positive mathematical expectation.


Microgaming uses an old-fashion and plain approach in developing their slots - exhibiting their own inability and crude lack of ingenuity; they bluntly exploit the creations of other software developers. The new Microgaming is constantly delivering average-length cycles and average volatility slots. While in-between the old machines, one can still find very long cycle slots (for example, Bust the Bank and Break Da Bank Again) and some very short cycle slots (for example, BridesMaids and Castle Builder). 

Here are the top Microgaming slots by RTP and their attributes:

Break da Bank

  • Break Da Bank Again
    The rate of return (RTP): 98%;
  • We propose to test a version of the Break Da Bank Again and follow the length of the cycle;

Hot Ink

  • The rate of return (RTP): 97.5%;
  • Play free at the Hot Ink slot from the Microgaming;

Extreme Heat

  • The rate of return: 97.5%;
  • Play free at the Extreme Heat slot without registration;

NYX (NextGen)

The NYX (NextGen) has committed to developing high volatility online slots, settling in the middle between NetEnt, Microgaming, and Novomatic. They have created slots with enormous potential (for example, 300 shields and King Kong). 

Here are the top NYX (NextGen) slots by RTP and their attributes:

Jackpot Jester Wild Nudge


  • The rate of return (RTP): 97.867%;
  • Play free at the StarMania slot.

Novomatic (Novoline)

Novomatic’s slots become equivalent for huge volatility and the potential of winning (possible 1000x+ during any of the bonus features) throughout the years. Almost all Novomatic slots show capacity for massive winning. 

We have created a section where you can view the RTP of each slot and their hidden settings (like the probability of triggering the features, volatility, wagering rating).


Coming back to the question: "Which online casino software is the best?" we proved the point that:

Each of the above-mentioned developers (NetEnt, Microgaming, NYX (Nextgen), Yggdrasil, Novomatic, and PlayN Go) holds a title for any player, whatever his attraction, age, and play level might be. Following its own market development plan, each company chooses its separate way wishing to entice different categories of players. Maybe the only exception is Microgaming, as they are exerting themselves on copying the successful slots of the other software developers.

  • Seeking slots with first-class quality but average characteristics and no special prickle - choose NetEnt.
  • Seeking slots with little more volatility despite the lower quality and performance - choose Microgaming.
  • Seeking slots with more volatility and higher potential of big winning - choose NYX (Nextgen).
  • Seeking slots with huge volatility and significant potential of winning even with small stakes - choose Novomatic.
  • Seeking slots with high volatility, remarkable features, and high-end quality- choose PlayN Go.
  • Seeking slots with custom solutions and exciting bonus features - choose Yggdrasil.
