The "All wins pay adjacent" payout mechanic is quite interesting too, as you can score a small win just from three matching symbols on a payline on the center three reels. I am so used to slots paying out left-to-right that often I don't spot this type of win, or even those in right-to-left order, and it's quite nice when what you thought was a dead spin turns out to be a winner!
The paytable is quite generous, especially for the three of a kind wins. If you win on this game, you have made a profit - it might just be 1x your stake of profit, but that's better than those games that have a tonne of tiny wins that don't even give you back your stake!
This is a perfect example of a game that worked pretty nice for twenty big money spins whilst on a night out in the casino, but doesn't really translate so well to the online world. There just isn't enough to keep you interested for more than a few minutes of play, and the mystery symbol feature can often be a huge disappointment, as opposed to a huge benefit.
