Your objective: fill in the 9 ? 9 grid so that each column, row, and 3 ? 3 block contains the numbers 1 through 9. The principle is elegant in its simplicity but, as you will discover, challenging to master. The 150 Sudoku puzzles in this collection from Mensa, the international high IQ society, have been designed to test and stimulate your logical processes through three increasingly challenging levels of difficulty.
