I never saw a sudoku 2×2×2 cube before, but sudoku have 9 numbers.
Is it hard to solve? I don't think so.
basic sudoku rules, each row and column 1~9, no double number. each face no double number,
so it is not suitable in 3x3x3. because 3x3x3 each row and column has 12 square. 1~9 must double number.
if you not to remember the number pattern, it is very hard to made sure the first layer. Certainly the first layer finished, all under control.
