I must be doing something wrong or missing something. I am working on the hidden picture puzzle with the grid paper. Per the directions, the numbers tell how many squares are to be darkened. I do this and get nothing that looks like a picture. I checked the WT and the numbers across the top and down the side are different from the numbers on my grid. On my grid, there is one "10" on the top and one "10" on the side. On the WT, there are 2 "10"s across the top. Can anyone help? Is this a random puzzle? I am trying not to skip the puzzle since it seems straight forward. Any tips? Thanks.
