I'm minded to believe this is true - here is a quote from BTG on an unrelated thread / unrelated forum:-
-----------------------
We would like to confirm that the make up of the wheel does indeed reflect the true value RTP. This would be a compliance issue (if we were not to display this) in Canada where we license games to the British Columbian Lottery and Lotto Quebec.Another compliance ruling in Extra Chilli is The Danish Gambling Authority along with other jurisdictional authorities, stipulated that we state the best strategy in the help, which in this case is to Gamble with the wheel. However, you need to remember that the difference is as small increase in RTP and if you collect 8 consistently the RTP is 96.15% it's just less volatile. Whether you lose or win on the wheel the RTP remains the same, long term.The WheelThe first spin is 50/50 and all proceeding gambles are 60/40 odds on.However on subsequent gambles the odds diminish to roughly a 1 in 10 chance of getting to 24 from 8.0.5 x 0.6 x 0.6 x 0.6 = 0.108 or 1 in 10With a natural scatter +4 it's 1 in 5 etc...You can work out the others by adding/removing the wheel progressions. The principle of the gamble is for players to push up the games volatility or not. A great deal of criticism in the Bonanza thread, was more often than not to do with the free spin frequency, where individuals stated they would like to see the feature more and wouldn't mind if it paid less (I'll have a look for the exact quote later). We have delivered the latter but we have also offered players something new, an option to raise the stakes and play a higher volatility bonus game or not.With Extra Chilli you have a great deal more options and comparing it to Bonanza is a little bit like comparing apples and oranges. It's like comparing Rainbow Riches to Dead or Alive because that are both 3x5.Just for the sake of argument, this morning, I donned my tin foil hat, flipped a coin ten times over 20 sessions to see how many it took to get a result of 5 heads/5 tails... after 20 groups of 10 I gave up trying realising that the coin was indeed rigged!My last 4 results...17) 1121211111 - 80% Heads18) 1121212222 - 60% Heads (closest)19) 1222222222 - 10% Heads20) 1111211122 - 70% Heads - gave up!However if you look at the bold section between 19 and 20 - I achieved 50/50 - just not during my set sessions. As always, happy to answer any other questions.Big Time Gaming official
