Normal sudoku rules apply. Cells with green squares must contain a positive power of two (2, 4 or 8). Cells with blue diamonds must contain a prime number. Digits separated by a white dot must be consecutive. Digits may not repeat in a cage. A gray line is a palindrome and must read the same from either end.
