Yes, I play this slot quite a lot and yes, I did get 4 wilds, once. The reel that wasn't turned wild was the first one, but luckily it had a green house on it so my win, on a £3.00 stake was £900.00. Very nice, but only happened the once. The claim is that Mr Monopoly can turn all 5 reels wild! I wonder what the payout for that would be on my usual £1.50 spin??!
On the downside, the game, like most slots I guess, can be frustrating. You can get reels turned wild with no win at all like the examples above, or just a couple of £. Also as noted, sometimes the feature triggers and gives you nothing at all, or just a small amount (I had a £2.50 feature win on a £1.50 stake just last night) no point at all and is very frustrating!
I'll keep playing it though, but it does have "dead" spells
