Works the same as every other slot. You press spin, it takes the money from your wallet, decides if you win anything and how much, then it displays a cinematic that is just a visual treat. Something to get you hooked and think there is more going on then there actually is.
Pretty sure its the same as every slot, Bonanza could have options when you hit the bonus;
Click "Start" to watch some cinematic that correlates to you winning $xxxx
or
Click "collect $1583 and skip the show"
xxxx = £1583 in both cases.
Seems jamming jars has less ability in its code to generate on the fly "reels" which leads to the same graphics sometimes. Possibly due to the fact its 'ways' are many times greater then Bonanza; forward, back, up down and a combination of all directions with wilds etc, looks very complex to me.
The math dictates what you see on the reels.
The reels don't dictate or affect anything.
