One thing that I don't understand with 3Dice is they have a lot of higher variance slots, yet, the "big wins" that I see posted here and there aren't that impressive.
They're higher variance in an interesting way, not necessarily ZOMG MASSIVE WIN HIGH VARIANCE, but more a case of not so much in the way of 'maintaining wins'.
Take a slot like Elements (Netent) for example, you've got 96% RTP and you've got a horrible wedge of that RTP tied up in 1-10x stake wins, same as Starburst.
These are slots that can roll for thousands of spins and not see a 100x stop trigger, but they are very good at maintaining a bankroll and giving a good feeling of 'value for money'.
Compare and contrast with Arctic Adventure or Super Suits or Enchanted Spins, there are massively less small wins on these slots (very much like the WMS slots actually), and they focus that RTP on what are, relatively speaking, regular wins of 50x or better, and especially 100-200x or thereabouts.
I think this is why so many people bust out a few times on deposits of $50-$100 playing $1 spins and decide that 3Dice is rubbish, it's an approach that you might get away with on something like Elements (especially with all the shite animations and other time-wasting rubbish that it bombards you with), but you only need a little bit of a bad run at 3Dice with that approach and it's game over.
I've never topped 1000x stake on 3Dice - (although their slots are definitely capable of it, Scatterville Skunks explicitly states in the paytable that it's got 6480x stake in there, which is a massive hit, and you only need to look at their Zeitgeist page for other examples) - but if you get involved for a bit of a session there, you really will start to see lots of 'nice wins' in the 100-200x stake region, and better.
It depends what you prefer I suppose, personally speaking I much prefer the 3Dice/WMS model to a lot of the deathly dull low variance trash out there, but that's an opinion/choice thing, rather than a legitimate reason to start casting aspersions at 3Dice overall, which is what some people seem to use it for.
