Most of the free wheel has a winning percentage like this which is 90% to the smallest reward then distribute the 10% on other prize on the wheel. Typically the jackpot winning percentage is 0.0000000….1% which is close to impossible to win.
This is what I hate on wheels. They should just put a small medium reward and distribute the winning percentage proportionally rather than put a huge amount while the smallest reward dominates the result of the wheel.
That's why it is called by jackpot because the chance to win the biggest reward is so small. This is also type of marketing strategy in order to make players to spin the wheels as many as possible because I am quite sure that many people are attracted to spin the wheels because of the possibility to win the jackpot although they are aware that the chance is small. Since the wheel is just a bonus, do not hope too much, it is better than nothing imho.
And I even doubt that alot of gamblers spinning the wheel actually have any knowledge of what the chances of winning the jackpot is in percentage. Not going to be talking about Betfury in particular, but majority of casinos if not all, purpose make their jackpot amount to be very high as a way to attract gamblers who will be headbent on winning it (the jackpot), forgetting totally to consider what the chances of winning the jackpot is. For me personally, when I see a game where the chances of winning xx amount (as a jackpot maybe) is below 0.01 percent, I simply consider that an impossible to win amount..
I have at a point some time last year, tried to win a Jackpot where the chances of winning was set at, 0.0001, I played that game over a hundred rounds every day for more than 4 months and never won the jackpot, I simply concluded that the jackpot is simply there to attract people like me, and that its impossible to win, and then gave up.
