Funnily enough, I went to Southport at the weekend, and into Silcock's Funland. A hell of a lot of machines there are the type that dispense tickets, with which you can go and claim "prizes". It's a little bit of a rip-off in terms of value, but I have to admit it does actually bring back a little bit of amusement back into the phrase "Amusement With Prizes".
Otherwise, video game wise, it was as Blackpool in the above post... HOTD (one of them, can't remember which), Time Crisis 4, Daytona USA (Which I suppose is suitably Retro now!)... and a game I actually quite liked... Can't remember what it was called, but basically you hunted dinosaurs with a rifle and a touch screen. It was probably called Dinosaur Hunt, but that's a bit too obvious. First go, and second place in the high-score table? Thank you very much. Lasted about ten minutes, too, which isn't bad these days.
Wol, did you go in Mr B's / Mr T's? It's the one across the road from Coral Island. They used to have a section of 10p/20p video games, but I'm not sure if they still do. Gems like Track N Field, Kung Fu Master, Asterix etc all used to adorn the back section near the bingo, as well as a six-player Daytona USA with cameras.
Otherwise, along the sea front there's an arcade called "Slots of Fun", which still had an OutRun and a Beast Busters in there last time I went, and in the Pleasure Beach they had an original Donkey Kong near the Log Flume.
I have no idea if any of these are STILL there, but it would be nice if they were.
Oh, the arcade at the far end of the Pleasure Beach, which probably isn't there any more now that they've made it compulsory to pay just to get in, used to have all sorts of classics, including a Hard Drivin'.
