A devilish new brainteaser! On the Icosoku sit 12 number buttons which can be positioned in any order. The challenge is to correctly position the triangles so that each number button is surrounded by the same number of black dots. For example, the number 7 must be surrounded by a total of seven dots from all of the surrounding triangle edges. Really challenging!
