Calculation of knowledge points and medals
Each completed game level in Adding doubles gives 1 knowledge points. You can collect a maximum of 2 knowledge points by completing all 2 levels.
In the game Adding doubles, you can earn a total of 6 medals. Medals are awarded based on how many times you have completed a level:
- Bronze medal: after completing 2 rounds.
- Silver medal: after completing 5 rounds.
- Gold medal: after completing 10 rounds.
Knowledge points are only awarded for levels you have not completed before, meaning those that do not yet have checked green circles.
