I think I would avoid saying you are going to make a clone of Candy Crush. That may run afoul of copyright rules.
People already know what a “connect 3” type of game is. No need to copy or appear as though you are copying King (the makers of Candy Crush).
If you are stuck on mentioning Candy Crush in your Gig so that people will know immediately what you mean, you may want to say that you will create a connect 3 game inspired by “Candy Crush” instead.
