Hi Guys,
Many thanks for all your help. after much deliberation we've discovered it's actually two games i remember roled into one. The first is jackpot and the beanstreak (which explains the cows and beans (eggs)) the second is note runner (or varient). I must have thought they were one and the same as I used to play them the same way (force streak). Used to run around liverpool emptying these and the barcrest hot stuff machines all week whilst at uni.
Anyway thanks again for all your help!!!
Cheers JJ
