Hello Seb, you have to check if those 45 strings are in the grid: 10,20,30,40,50,60,70,80,90, 12,13,14,15,16,17,18,19, 23,24,25,26,27,28,29, 34,35,36,37,38,39, 45,46,47,48,49, 56,57,58,59, 67,69,69, 78,79, 89. All of them are in the "20-box" -- thus all integers from 1 to 100. (We check only those substrings, not if they are linked together. 10 is visible twice: in the bottom right corner at least.
