Which games can I play on Wish Upon a Jackpot (UK)?
Gonzo's Quest
Join Gonzo on his quest for gold, and discover your own riches with this beautifully-designed slot. Make a match and the symbols will fall away, letting new ones drop into place for cascading wins. The wins will multiply each consecutive drop of the avalanche!
Roll up, roll up for fairground fun with the Fluffy Favourites gang! Plushy animals make up the cute symbols on the reels, and though brighter and more colourful than original Fluffy Favourites, Fluffy Fairground follows the same mechanics with a Toybox Pick bonus round.
