Lucky Balls Bingo Betting

Lucky balls 6/48 is a game in which player chooses 6 numbers out of 48 in total, where 35 balls are drawn in each game. When the six played numbers are drawn within those 35 in the game, the ticket is winning. The odd is calculated based on how soon in the game the player had matched all six numbers on the ticket with the numbers drawn.

I was calculated the return to player (RTP) using the hypergeometric distribution formula as the Wizard did for Bingo. I used the paytables for two bookmakers offering the game, William Hill & Lotto Instant Win. For Lotto Instant Win I got an RTP of 84% and for William Hill 102% !

Where am I going wrong with my calculation?

William Hill paytable: luckyballs dot rs
LIW paytabe: lottery dot live

My spreadsheet: ibb dot co/fQXyTK

If your paytable is correct (I can't seem to find it - I think you have to be registered with William Hill), then I get the same 101.935% return that you do.

I get a similar number through simulation.

Also, this doesn't take into account the "clover bonus" (two of the numbers from 6 to 35 are selected somehow; if that number of the draw (e.g. the 10th and 22nd, or the 19th and 34th) is one of your numbers, the payouts double, and if both of them are, the payout triples), or the "bonus game" with all payouts doubled, or the progressive jackpot.

Something about this doesn't pass the smell test. I would like to see the game as it is actually played.

If you go to the web site and click on the demo video, you will see how to interpret the numbers on the screen as a paytable.

When I interpret payout=1 as a push, then I calculate a net positive return of 0.019353, in agreement with ThatDonGuy.

I found a bookmaker using the same paytable as William Hill : www dot merrybet dot com/lucky6

I am wondering if you can look at it and confirm that the Bookmaker is betting at 101.935% RTP. This is a live operating bookmaker's site. Are they betting at a loss?

I put the LIW paytable through an own built simulator and the RTP was up to 98%. I tried to figure out the variance between the Excel Spreadsheet and the simulator. What I did was apply Standard Deviation to the spreadsheet and got very close to my simulator RTP.

Is it possible to get different results from a spreadsheet and a simulaor and if so, were I right in applying SD or am I barking up the wrong tree?

Can someone please post the pay table or a link to where it can be found?

Either this game is indeed paying 101.95%, not including the Clover Bonus, whatever that is, or it is gaffed. Either way, I will dig deeper.

Anyone feel free to PM if you want to tell me anything confidentially.

I just finished a first draft of my new page on Lucky 6 35-48. I chose that title to differentiate the game from a different game I title just Lucky 6. What you will probably be most interested to know is that with the Clover multiplier feature, assuming the clovers are randomly distributed, the return is 134.6%.

I'm off to Burning Man on Saturday and won't have time to do any testing for fairness of the game until my return and even then I'll probably be swamped catching up. Meanwhile, I will post the page, but won't draw a lot of attention to the high return. Leave that to the astute players willing to read carefully.

I seem to remember that I calculated a similar value (134.6%) for the return with bonuses.

In situations like this, I try to imagine/recreate the error that someone might have made when doing the math analysis that underlies the payout table. So far, I can't figure out any math error that would explain this situation.
