Unfortunately it certainly does make a difference!. This is evidenced by the fact people use to go for whale playing funky five at 5 cents a spin and would hit the bonus game nonstop as well as the wilds.. the minute you up your bet to around 1.00 it completely pays differently. I am 100% certain about this. It is the same on Club Sanguine.. 20 cent bets award the bonus round more frequently than 1.00 bets. So, whatever the case may be it is not true that small bets pay the same as larger bets. The RTP is 100% different. I have spoke to about 10 people that play religiously on 3dice and they all notice the differences as well.
I think this is one of the reasons they changed how the shark and whale achivements are awarded. It was too easy for people to get them with the lower bets.
I also played the new infusion game going 1.00 a bet and ended up around 1800 spins with no bonus game. I lowered my bet to 80 cents and had bonuses nonstop over and over again and some huge wins. So I dunno.. but they do pay differently.
go test it for yourself compare 2000 spin at 5 cents a spin on funky five and then do 2000 at 1.00.. tell me there is no difference
What you're effectively claiming there is that 3Dice are misrepresenting the RTP that their games are running at, which is a pretty big accusation to make with nothing other than anecdotes instead of evidence.
IIRC it was only Whale that changed, and Shark stayed the same? You could argue that Whale was perhaps a bit too easy to grind out on something like Funky Five, which has pretty high RTP, isn't overly volatile, and can rattle through the spins too. It's a bit of a shame 'cause as a low-roller myself I would occasionally have a punt at Whale, but ultimately it's up to 3Dice how they organise the perks and bonuses.
