I like doodling and had an idea based on a flash game, where numbers are hidden in a picture, and it's ended up better than i expected. So have fun with it. And if you can give feedback on it that highly appreciated.

Every whole number from 1 to 50 is appearing once in the picture below. Better quality picture here.

Disclaimer: since it's hand drawn, besides my best efforts, there are some fake positive answers (where its kinda looks like a number, when its not supposed to be). But i think if you find the right answer, you know it is the right one.


There can be some answers which are not Arabic numbers.

  • $\begingroup$ I think all depictions of '7' have the line through the middle, meaning you don't have 27 circled. I think that's supposed to just be 2. (I have found 27 somewhere else where this rule is followed.) And I don't think your number '1' is right. If you turn it the right way up, that would be backwards. Also, good luck with 12, 19, 35, 41, 43 and 46. I found them to be quite sneaky. ;) $\endgroup$

  • $\begingroup$ Yes, that's a rule for the sevens to make them clear. And yeah those are meant to be sneaky. :D $\endgroup$
