I can remember when I was about 15/16 (I am now 45 lol)
There were a lot of hip height/half size fruit machines, and they were blue in colour.
I think the max jackpot was either 2 or 3 £.
I remember them being in Ingoldmells arcades at the bottom of town, BJ's nera the pub and outdoor market.
Any help on the name would be nice.
