Well that was awful. No logic, multiple solutions and that 5 does start in c20 not c19. How this got a rating higher than 1/10 I will never know. Please for the love of god, check your puzzle before submitting it.
You're welcome Sena. I noticed you already solved the puzzle. Posted hints for future solvers since the images for the puzzle are posted on a different page. :)
Just like favorite authors, I have favorite solvers too! (Sometimes the same person is in both categories.) Teesea & Strigoii, you are incredible. Thanks!
