@JDev: lots of the card will still be brown once you're done, but you should see a nice picture. Perhaps one of your answers is wrong, making a mess of the picture?

I finished all of the puzzles but the picture is far from colored in. Am I missing something?

These puzzles have been a blast!

@Tara: I initially made the same mistake. Maybe you didn't take into account that 6 is not one of the available digits in question 1?

@Tara: Yes, looks like you may have got an incorrect answer for one of the black puzzles

First, thank you for this gift. This was just what I needed to get through my day.
Second, I feel that I did something wrong, I see the picture, but I'm struggling with the fact that I did not color 4 and 13 black. Did I do something wrong?
