Are these slot related or not?

[coppinpr]

Someone has asked me if I know what these plastic beads are...I've no idea! anyone seen them before? some of the questions on the papers are quite high brow (what is the atomic weight of radium?). Quite possibly not slot related at all,but who knows....please
If nothing else they are very odd.

Atomic Number 88.
Atomic Mass 226.

yes but now the difficult question....what are these beads?

[daveslot]

Yes slot related, they were used in a baby grand vending conversion, you got one bead for 6 d

thank you Dave

Fascinating!
Was there any gameplay involving the questions?

[coppinpr]

I suspect only in the same way as asking others the questions on xmas cracker mottos, However the fruit machine symbols and the numbers printed on the slips (and over stamped as well) hint at a random chance to win a better prize across the counter in the same way as a trade stimulator worked .Perhaps you even had to correctly answer the question to receive your prize (operators never liked giving anything good away for nothing
