The Colgate Magik game is full of treasures.
You have to travel through a set of imaginary worlds to collect masks. There are five masks per world.
You will be guided to brush 16 zones of your teeth. If you brush the correct zone and defeat the monster, you will gain diamonds. You can earn up to 15 diamonds per zone. With perfect technique you can collect up to 240 diamonds in one brushing session - this is almost enough to purchase the unicorn mask!
The diamonds will allow you to buy new masks to try on in the photo booth.
At the end of the brushing session, you will see the stars you won. The number of stars is decided by the number of diamonds. The more diamonds you get, the more stars you will.
