Used to play it a lot in the local nobles, pretty boring machine after a while and the sounds are terrible. Good for boredom though, normally £3-£8 for a £5 jackpot.
I'm sure fun in the sun was one of the first ever £25 machines because the jump was £8 for red sevens to £25 for jackpot. Wasn't an terrible machine but it replaced an unchipped red arrow in the bookies near me.
