My personal experience with Ra Magic has been terrible too, plenty of others with the same opinion. However I’m sure the last time I checked the RTP on Videoslots it was pretty standard, which indicates it is paying fairly to probably a wide spectrum of players.
I found Magic Mirror absolutely disgraceful for months, not managing a single bonus over literally thousands of spins. Then all of a sudden I hit 1000x+ on the bonus and had a couple of other nice bonuses and it recovered my RTP nicely!
Perhaps this is just one of those slots that takes time to balance out.
