Arcade

The backbone of a floor. Five different cabinets so a row of them does not read as one machine repeated, and the cheapest go in the building.

A seat, a wheel and a longer go. Guests sit down to play it, so it holds them longer and earns more per square metre than a stand-up.

Hands a prize over. You set the odds and the quality of what is in the bin, and a winning go really fishes a teddy out of the pile.

Fifteen plush animals in the heap, from a panda to a unicorn. The claw is steered, dropped and closed for real, and the animal it fetches is the one the winner carries round the park. Each one plays its own little tune.

Reels, lights and noise. Pays an arcade token every go and a jackpot of six to twelve when the reels come in - the only source of tokens in the park.

The same bet in a different cabinet, lit like a fish tank. Pays a token a go like its neighbour, so a pair of them fills a prize shop twice as fast.

Two guests, one table, and they arrive together. A machine that seats a pair pulls families off the path in a way a row of cabinets does not.

The busiest thing you can put on a carpet: four guests at once, and the longest go in the arcade.

A pair of pads, and the guests stand on them rather than sit. The most expensive machine to build and the one people watch.

One or two guests squeeze onto the bench, the curtain closes and the flash goes three times - you can see it light up under the curtain. A strip of photos comes out of the slot for each of them, and they are delighted with it. Two friends pay once between them.
