Some Yorkies, especially tiny, young puppies or anxious ones, are too fearful or skittish to be sprayed with water or citronella or things like that but mostly anything will work to stop them as long as you show you are displeased when they bite. Just try any of the advice you've been given above from yelling and immediately stopping playing with the dog; saying "no", getting up and walking away, gently grabbing and holding onto the little muzzle for a few seconds or anything to express your dislike of this behavior and replacing your fingers with a toy or chewie or get him playing with something else will eventually get through to your dog and he'll begin to soften or avoid his biting you as he learns the outcome of it displeases you. Dogs use their teeth as we do hands and arms and often just bite out of excitement or passion but it can get downright painful and lead to a dog thinking you are pretty much his patsy if allowed to bite hard any time he wants.
