Math Glass

Initial levels can be solved by a primary school student. At later levels one simply discovers that the human brain is too limited to test all the possible combinations to find the solution. This is where the mathematical ingenuity is required to find shortcuts in order to succeed. At the end, a diligent player will discover basic tricks of number theory.
