Combinations – n choose k

Learning comnbinations in math is normally not easy or even frustrating.
With the „Combinations - n choose k“ game it suddenly becomes fun to practise those numbers! You start with three lives and you lose a life each time you get the wrong answer. You also play against time, so every 20 seconds you lose a life if you haven't reached the next level at that point.

As you continue the game gets harder and harder, so don't expect to get bored with this app!
