Normal Sudoku rules apply.
Each group of same-colored cells forms a perfect power family —the base (x), the square (x²) and the cube (x³).
The cage in Box 1 contains the digits (read from left to right) of the square of the 9th prime number.
FOG OF WAR: Not all clues are visible at the start; correct placements will reveal new cells and clues.
