Gifts fall out of the sky and you tap each one before it lands. That is the entire game, and the only thing it adds over time is speed — the drops get faster and more numerous until the screen is asking for more taps than a person has fingers. Missing a few is survivable; missing a run of them is not. Jingle Drop Challenge is the purest reflex test in this batch and takes about ten seconds to understand, which is the point of a game like this.
