Fruit Machine Chat

Was in a pub this morning and some blokes start looking at the back of the itbox I'm playing. Asked him what he was doing and he said he had to change it to a gamesnet.
So he wheels it in and I'm thinking that being the first person to play on this machine I'll clean up.
I won six or seven quid on one game and moved on to a different game - straight to spoilers. Tried another - same thing.
I thought the games weren't connected in that way. Surely this proves they are?

It probably wasn't brand new, just re-sited from elsewhere in the same state.

games are NOT connected. Winning on one game does not affect the chances on other games.Its likely to be a combination of :
(1) A pro has been on it
(2) Some games are constantly shit no matter what money is put in
(3) When a machine is updated games are often reset to their worst level to enable the machine to fill up.They DONT want to introduce a machine in happy mode particularly relevant to a new site.
