Was there is a slight clue on the pie gamble? Corals had a game called Power of Olympus, it was £100 with a pre-stake pie gamble wheel.
Yes on the older version.
The mega spins wheel would be showing 3/4 (or more) in yellow (win) and offering 20-24 Mega Spins (for gambling a decent win, say £80 or higher)
This was a way of saying "Touch here for a pretty much guaranteed £500 JP" lol.
They still have 2 of the pre-chipped versions in my local Admiral but rare I bother as getting a decent feature would probably cost more than the JP itself lol!
Did have a £120 win (on 0.50p bets) and had this opportunity about 6-7 weeks back and even though I knew I had a 90% chance of the £500, I was that skint and "out of touch" I collected the £120! (regretted being a pussy for days after)
