It might be illegal

yeah you need a gambling licence. you are also better off renting a fruit machine.
that way the people who own it will put it in your pub and pay you for having it there (meaning you have no layout) they will also replace it if it gets broken and update it when it gets old!
Good luck

yes you do,you have to apply to your local district council for a gameing licence.

You need a gambling licence. Rent one – its cheaper for you, and most pubs update their machines once a couple of people have had the jackpot out of it.
