From the Store description:
There's a new player in town, the wiggling, jiggling Jelly Queen and she's here to challenge you to a game of Candy Crush Jelly Saga! Whatever your favorite moves, you better hope they're Jellylicious enough to take on the mighty Jelly Queen.
The unstoppably spreadable game! New Candy Crush Jelly Saga is full of delightful new game modes, features and boss battles featuring the Jelly Queen! Playing as Jenny, show off your Jellylicious moves and take turns switching Candies against the jiggling Jelly Queen. Every sweet move will spread more Jelly and whoever spreads the most will win the level! Have you got the moves?
There are splendid new Candies, a marvelous new booster and a dreamy treetop world to explore in the Candy Kingdom too!
I'm not going to dignify this title with screenshots, but there's a promo video that will make you throw up explains more about the aesthetics and feel of the game:
If this is your sort of thing (or your partner's) then head here to the Store to get it. Just watch the in-app purchases - they 'only' top out at £20 each but, like all the Candy Crush games, the gameplay forces you to keep adding in real cash, and many know to their expense how these can mount up!
