If I'm not mistaken, the current highest slot machine progressive jackpot online is Bovada's Shopping Spree. The jackpot is currently at $4,013,009. Our sister site, Casino Listings says he has been hit once only, over seven years ago.

I've been tasked with estimating the return of the game. To start, the progressive is won if the player gets five diamond rings on an active pay-line with a max bet. The max bet is $1.25 over 9 paylines, for a total bet of $11.25.

Just to do a quick and dirty estimate for now, I first recorded the frequency of the diamond ring symbol on each reel. Keep in mind there are three visible positions per reel. Here is my count after 100 spins:

Reel Count
1 7
2 11
3 8
4 5
5 12
Total spins 100


A little math leads us to a jackpot probability of 1 in 7,305,195 with 9 paylines.

Given a full bet is $11.25, the return from the jackpot is 4.88%.

As a rough guess, I estimate Bovada slots to return 95%. Let's say that 2% is in the form of meter contribution, so 93% for the fixed pays. That would make the overall return 93% + 4.88% = 97.88%.

Questions or comments? I welcome others to gather more diamond ring data. You can play for free here.

The question for the poll is will you play Shopping Spree?

It's not whether you win or lose; it's whether or not you had a good bet.

What is the $227,298.64 number on the upper right hand of the screen?

That's what it shows the jackpot at in free play mode. It means nothing.

did you play it in demo mode or with real money? Only asking because I would assume in demo mode they turn up the return to make it look better and get people to play. If that is the case then the frequencies could be off. If you played for real then nevermind.

I've never witness a demo mode game that operates this way.

I have many many times. It is not unusual to put a much higher paying percentage game in Demo mode.

Demo. I still think it's the same game.

What makes you think that? I would assume otherwise unless I knew something specific.

I really should be working, but...

Assuming that the play for free reels are the same as the regular game, I think each reel is 32 long, with 1 diamond ring each. This makes the progressive 1 in 3,728,270, when playing all 9 lines.

Your diamond results are feasible given the assumption of 1/32.
I heart Crystal Math.

I think I forgot to mention that Shopping Spree can be played for free at Bovada.
