It’s un-wheel…
The concept is simple: there are two wheels with a win total in the centre. Each wheel’s size can be adjusted, and as you make the exposed area of each one smaller, you’ll see the win total in the middle of the screen increase. This is because the aim of the game is to line up both of the wheels’ exposed areas between the two arrows at the top of the wheel. Therefore, the bigger the surface area of both wheels, the easier it is to land them on the dotted line and the smaller the win will be.
