I've never been a Candy Crusher but I have such an addiction to the Jewel Quest games.
I started out with Bejeweled but found that I liked Jewel Quest much more. When I was in China, I worked my way through Jewel Quest I, Jewel Quest II and Jewel Quest III. Then I got carpal tunnel syndrome and I couldn't play Jewel Quest anymore (repetitive mouse action).
To my delight, Jewel Quest was available on the tablet so I could play it on my Nexus 9. Alas, only Jewel Quest Heritage was available:
Fortunately it took me ages to finish but as I approached the end of the game, I wondered what I'd do ...
Then work gave me a Microsoft Surface ... and I realised that while it had Tablet features, it also functioned as a 'normal' computer so I've gone nuts and installed all the other Jewel Quests on it ... Jewel Quest the Sapphire Dragon and Jewel Quest the Sleepless Star.
I love the graphics in the Jewel Quest games and the music and sound effects are wonderful, too :)
