The square playing field is arranged in three blocks of three, whereby each block consists of nine boxes. So the entire playing field consists of 81 fields with 9 rows and columns. Between 22 and 36 fields are predetermined with numbers between 1 and 9, depending on which level of difficulty you choose.

Now you must complete the whole puzzle with the right numbers, provided that in each line, column and every block the numbers from 1 to 9 only appear once.
