"In each sudoku, enter 4 of the digits 1-9 in each row, column, and 2*2 region. Digits cannot repeat in any row or column in the 8*8 sudoku grid."
Can digits repeat in a region? I.e. r1c1 and r2c2?

Love this kind of puzzle. Figuring out how the different 4x4s interacted was fun and led to a great solve
