Here is an adaptation for kids of the classical game “Mastermind”.
The goal is to find the 4 good colors, but to allow the young children (from 6) to play, we added an easy mode with only 2 colors, an intermediate mode with 4 colors. The hardest mode contains 6 colors. 
Several decors are available and children will win trophies while playing, to keep them motivated.

Become the “Mastermind” colors…
