I say avoid one in peterlee, lots of the machines in there can suck in a good few quid before offering a board where no wins are offered, and most of the £500 jackpots are reserved for a week for people who put in hundred of pounds into that machine (which i kind of think is wrong). There is deal or no deal - dream factory (which always seems to reset when you get invincible or on a Mega Streak) there and a Pot of Gold at £70 Jackpots (which seems to kill you off on the first Hi-lo Gamble)
Or maybe i just had Bad luck
