I'l save you some time other than Happy days there are no other 3 player streak machines along the coast.
There is a single unit in Funland but again this is most of the time closed!
Although I havn't been to Morecambe in a while but doubt there are many changes !
Was in Southport last month but never saw the slot.
Morecambe has become worse to be honest as hardly anything is open on the promenade side, but I was just told by my Dad a few hours ago that they have removed the 3 player streak machine from the pleasureland amusement but they've returned the 3 player hokey cokey and big ben....so that is a trip saved.
I guess somewhere, they'll be a 3 player streak machine as their are quite a lot of Single Player versions lying about...
I will be making a few trips to Blackpool during the upcoming week and I will see if they have The Steak 3 Player Machine in any of the arcades (although I know most will be closed for the December Period!)
Except from Coral Island, Fun Palace, Star Attractions (formerly known as Mr B's).
Doubt any of the above will have one in (but I know Happy Dayz does but that isn't open til mid-january) since Coral Island is mostly filled with the new Crazy Fruits Community, Golden Game, Batman Begins, Crazy Fruits (Single) similar to Clockwork Orange, Lady Luck, Bullion Bars, Party Time Classics within the 10p range area.
But will try my best to have a look around, if not I will make a trip to either Southport or Morecambe during the week.
