Candy Cup Saga is a puzzle game for Series 40 where you have to match candies to score points.
Unfortunately, Candy Cup Saga lacks all the charm and cuteness of the game which clearly inspired it, Candy Crush Saga. Graphics are rudimentary, it lacks music or sound effects, and an ad obscures the bottom row of the grid. It's simple enough to play but lacks any fun factor given its bland implementation.
If you're looking for a semi-decent Candy Crush-style game for S40, try Candy Pop Saga instead.
