The maths of the Wheel (probability/odds)

Have you actually tried to get the last prize thread creator??? The wheel is without doubt RIGGED, it speeds up and slows down to stop you getting that last prize. The number of times I spun that wheel and could see I was going to land on the prize dead on, only for the wheel to splutter to a grinding halt prematurely, almost had me launching my tablet against the wall.

Your probability model would work fine if the wheel spun FAIRLY at a consistent speed all the time, but it doesn't. It took me 73 spins to get the last prize, my gf took 65 spins. Are we really just the unlucky 1% or is it plainly obvious the wheel is rigged?

Nope.

Whether you win the prize or not has already been determined a long time before the wheel stops spinning.

Heres how these kind of things work.

When you set the wheel in motion, it will make a call to a random number generator, for the purpose of this example, lets say the generator returns a number between 1 and 100.

If the number returned is:
1-10 - You win prize one (money)
11-20 - You win prize two (money)
21-30 - You win prize three (money)
31-40 - You win prize four (money)
41-50 - You win prize five (money)
51-60 - You win prize six (money)
61-70 - You win prize seven (money)
71-80 - You win prize eight (money)
81-90 - You win prize nine (money)
91-100 - You win prize ten (the last non money prize)

This number is returned the instant you start the spin, what happens after that is just for the benefit of making the wheel be an actually wheel, rather than an arbitrary value that determines whether you won or not.

What is likely occurring is that depending on the number returned by the random number generator, it chooses a 'wheel animation' to play for you.

I don't know how many different animations there are, for the sake of this example lets say there are 3.

If the random number generated is:
1-45 - The wheel animation lands nowhere near your prize
46-90 - The wheel animation gives you the impression you are going to win, but you don't (tease animation)
90-100 - The wheel animation lands on the prize you want.

As I said, thats just an example, there could be many more than three wheel animations, but the point of my post here is that the random number that determines whether you won the prize or not will have been returned the instant you set the wheel in motion, what happens after that is all for show.
