Sorry Harry I haven't played ninja ways, maybe red tiger have done something different with this slot. laser fruit didn't have a bad hit frequency but the bonuses didn't live up to the potential. I think it's their games where there is a random bonus that really struggle.
Stimulated by your post though I just popped onto their website and when you click on each game for more info etc.. you can play the games in free demo mode but also underneath each one they tell you the hit rate [ not the actual number but a rating] and the max win.
'laser fruit' has a hit rate of 4/5, max win 10,000 and volatility 5/5, contrast that with 'treasure mine' which has a
2/5 hit rate and a
2/5 volatility with a max win of 1320x

I'm sure that's got random bonus features which must bugger up the hit rate as the rtp is diverted into occasional 15-20x random wins, and it just teases you with them too many times
Rocket men, one I've had the displeasure of playing is 3/5 volatility, 3/5 hit rate and a max win of 624x and yet on the 'pays' page it states win up to 1000x
I must admit looking at their own ratings, the games do seem to differ from each other but every time I've played them they feel very similar, small pays and lots of teasing

Just playing a few on demo mode on their site and I've never experienced so many wins and random features appearing, these must be enhanced versions to 'demonstrate' the potential.
