This is poor for online slots where a proper RTP is in the 95.5% to 97.5% range (which is where most games at NetEnt and MGS are sitting).
I'm actually surprised that the big players in B&M casinos haven't been able to correctly adapt their product online. IGT is a prime example, but even WMS online isn't on par with their real slots. Same with Aristocrat, their online slots don't look as good, don't run as smooth and still carry the lower B&M RTP's.
Not impressed by the big boys here but I guess that it's not their primary market so they don't really care.
Most of IGT's games go to the right side of 95% too but unlike Net Ent & MGS, they do a range of RTP's while the others are fixed. Ghostbusters is lower as it's both branded and low variance. For example, the Playtech Marvel 50-line games are all around 92% while their higher-variance 20/25 line counterparts are closer to 95%. As a rough guide, the higher the variance of a branded game, the higher the RTP.
