In Prime Run Sudoku, the clue outside column 1 is 9, but the sum of first three continuous prime numbers in that column is 10. Also, in column 6, the outside clue is 10, but the the sum of first three continuous prime numbers from that direction is 11. In row 1 also, the outside clue is 3, whereas the sum of first two continuous prime numbers is 4. Is the example in the ib correct or i have misunderstood the rules

1 is not a prime number :)
