I don't know 100% but I think I can try.
So basically you have 2 screens.
First of all you play normal bets and start spinning.
When you hit something you can take the money or useΒ the win to place a higher bet and then the second screen is used.
So if you bet 1euro and you win like 10euro you can use the 10euro for the big bet and just for one spin.
There are 3 bonus aspects for the bigger bets. The jokers can pay like a scatter based on which bet level you play on the second screen.
Like just for the middle wheel or on all wheels.
After you win on the second screen you can take the win or continue playing higher bets with the jokers as scatters.
On top of all there is a hidden jackpot which can you win with every spin.
I guess that's the game
