Re: Jennings Governor 'win percent' rate question...

Bit tricky to work out the percentage on a machine without a declared jackpot amount. Basically it's a case of coins out as per the award card possible combinations [taking care not to duplicate when there is 'any' in the win line] divided by the total number of possible combinations then multiplied...

Re: Harper’s Volta? Electric shock

Ah righto, it was the fact that they are both dated 1899 that threw me a bit off course.

Re: Harper’s Volta? Electric shock

So does that leave us questioning the validity of the Nic Costa entry of the Electric Volta by D. Harper and Co., London, 1899?

Re: Harper’s Volta? Electric shock

I thought it may have been the Electric Volta as listed in the Braithwaite book under 'D. Harper, London, probably a supplier' but there is an Electric Volta by D. Harper in Nic Costa's Automatic Pleasures which is entirely different to the ebay one. No mention of the 'D' on the label in the ebay on...

Re: Jennings Governor 'win percent' rate question...

Malc, do you remember when you kindly helped fix my Roma with the coin not retaining in the gate and 'round about that time I had calculated the percentage payout to be 49.6%? You agreed that the problem lay with the wins with 'any' at the end. It's easy to kind of 'double up' with combinations eg o...

Re: Jennings Governor 'win percent' rate question...

As you say Malc, these days in the UK operators have to display the average percentage return to player/payout - you may need sharp eyes to see it. There is no legal minimum but the industry suggests it should be a minimum of 70%. Mills bandits were factory set at 74%. This is over XYZ plays which c...

Re: Jennings Governor 'win percent' rate question...

Hi spumker, welcome. I am not a bandit man and know little about them but I do like to work out payout percentages. Bear in mind that the 'chances of winning' differ to that of 'return to player percentage' and it is this that the 75% refers to. I have only looked at your table number one (without t...

Re: Hawtins allwin - a fair price?

Mmm...except that 1929 would be MCMXXIX and there is no such number as XXVIV.

Re: Jungle Skill slot machine

The missing 'tubs' may be because a greedy operator removed them so the ball (the machine should have one steel ball in it) will most likely go into the lose hole, situated in the middle of the innermost track, or may have just broken off. !PUZZLED! The area you have circled at the lower right of pi...

Re: R&W Many Happy Returns Allwin

Yes, that period would be about right. Most likely to have been made by B.M.Corteen Ltd. badged and distributed by Ruffler and Walker. Corteen was at Croydon at this time, moving to Erith about 1956.
