Prime Knight travels through Prime Country... Ride along and Document Details of his Journey

As this Prime Knight (only chess move allowed) journeys through Prime land, he makes a pit stop at every successive prime site. No cell is ever revisited.

There are 64 of them..starting at 2 (cell A1) and ending at 313 (C8). The numbered cells shown in the picture are mandatory stops.

$List$ $of $64 $Prime $ $Numbers$

2,3,5,7, 11,13,17,19

You can get lost and miss the mandatory stops if you don’t take the right path.

Document the journey in chess notation

For example...A1, C2.......so on...ending at last pit stop at 313(cell C8).

Or present picture with all the journey stops.

    $\begingroup$ Why prime numbers? That's just a hassle... $\endgroup$ Jun 15, 2019 at 14:25
  • $\begingroup$ He is prime knight...does not know other numbers..you can always number the primes 1 to 64..after you solve, you can substitute the primes $\endgroup$

  • $\begingroup$ Uh, your list of primes is only 63 long, (it's the first 65 primes without 7 and 157) [Note: This was annoying as I just spent a while trying to crack it assuming it was meant to be the first 64 primes :(] $\endgroup$ Jun 15, 2019 at 15:40
  • $\begingroup$ I am sorry, I missed 7 in the first row..editing now $\endgroup$

    $\begingroup$ Or, like, you could've not used prime numbers to begin with. $\endgroup$ Jun 15, 2019 at 19:37

1 Answer 1


Getting the ball rolling with some initial thoughts...


Bold - Certain
Not Bold - Hints, like those in Sudokus


C2 must be 3 for 2 to reach 5


107 must be F1 or F3 to link 103 to 109


7 must be D3 or D5 to link 5 to 13


11 must be E1, E3 or F4 to link 7 to 13


F2 and G2 must be 251 and 263 to reach 257 at H1

Grid after Step 1-5:

  • $\begingroup$ Nice...looks more visually appealing..he is very tricky Knight $\endgroup$
