In Smile Rush, you take on the role of a dentist who works to make all of his patients smile in a way that is both attractive and healthy. During the course of the 3D track, your objective is to gather teeth that are clean. The screen will display one or more teeth that have a tendency to rush forward and progressively gain pace. In front of you, a treadmill will emerge, and on the screen, its teeth will appear. Avoid obstacles and dangers that might slow you down or do harm to your teeth as you are trying to collect as many clean teeth as you possibly can. The circuit is full of twists, turns, and leaps, all of which require exact timing and navigation abilities, so you will also need to be nimble and flexible in order to complete it. Following that, at the conclusion of each level, you will place new teeth in the mouths of all of your clients, and you will be rewarded with points. Have some fun!
