Don't mean to be rude here lionbleu, but everything you're complaining about is covered in the help file.
It explicitly states that the fortune wheel itself does not represent true odds:
The Chocolate Wheel in the Bonus feature of this game does not represent a "real", physical wheel and the probabilities of it stopping on any particular spot is determined by the game's random number generator, and not the number of positions on each wheel.
i.e. Your actual chances of hitting the mega jackpot off the centre wheel are more like one in fifty million rather than one in twelve.
And what you're left with after the very hefty progressive contributions:
Mega Fortune contains Mega, Major and Rapid Jackpots. The following contributions are made from each bet:
1% of the bet is contributed to the RAPID Jackpot.
1% of the bet is contributed to the MAJOR Jackpot.
5.39% of the bet is contributed to the MEGA Jackpot.
Is a pretty low variance base game with an RTP of 89.21% which is an absolutely horrible payout and that's why they've pegged the base game as low variance, as anything more than that would render it even worse to play in terms of ever getting any half-decent wins.
Think of this slot as a lottery ticket.
Deposit some money, play a couple of hundred spins, take some shots at the wheel, and walk away when you don't win.
Plugging away at Mega Fortune in the hope of hitting a jackpot is comparable to buying a thousand lottery tickets per week instead of a couple, on the basis that you're 'more likely to win'.
Yes, statistically you are more likely to win the more you play, but you're still just adding the tiniest little chance on top of the tiniest little chance.
The mega fortune wheel itself is just an illusion, and in all honesty it should be clear that it HAS to be an illusion, otherwise the slot would be dropping mega jackpots into the laps of every player who cared to put a thousand spins through it.
