Cube Rubik

My son Danish Haikal 4 years old like playing games that need us  to make match  such as "Pairs Game" , "Jigsaw Puzzle" and anything. He also enjoy playing with  "Rubik Cube" toy. But the problem he always quick to despair, when he can make match at the first level for example he match the first row like blue color. When he want to match others it's difficult so he become give up. One day he got an ideas when he see that one sheets cube can uproot so he decide to throw the cubic so that all sheets uproot then he merge the cubic according to the color matching again......huh my son..:)
