This is great and color combination brain teaser puzzle (also known as 'traffic light' puzzle).
The puzzle has 4 cubes with different colors.
There are 3 different challenges to be solved where in each one of them you will be asked to arrange the pieces and colors in a very specific way as follows:
Challenge 1 – arrange the cubes inside the wooden frame (in a stright line) so there are 4 different colors in each side.
Challenge 2 – arrange the cubes out of the wooden frame (to form a square made of the 4 cubes) so there are 4 different colors on the top and bottom, and 2 different colors in each side.
Challenge 3 – arrange the cubes out of the wooden frame (to form a square made of the 4 cubes) so there are 4 different colors on the top and bottom, and same color in each side.
Very challenging and fun puzzle to play with.
