When you play Goldbuster the goal is to answer different kinds of math problems correctly. Each time you complete a set of problems, you get to see a short, fun animation. If you answer all of the problems correctly, you win a gold medal. Goldbuster is available in four different versions: - a free version with 9 problems- a version for ages 5-9 with three levels and 500 problems- a version for ages 9-12 with three levels and 500 problems- a version with basic multiplication Goldbuster was developed by Aschehoug in collaboration with Annette Hessen Bjerke and Extransit Malmö. Animations were created by Tommy and Markus Vad Flaten.
