There's conflict in the review section of if this is easy or difficult. I'm on the side of it being very illogical. Even with Debbief25's comment, there was two answers near the end. If you don't know the symbols, you'll be in for a ditty.
I didn't know this symbol and got it on the first try. there are two fifty fifty choices on the left side, and if you make the choices that make a connected shape, you'll get it on the first try, too.
Hint::: the 7 in column 1 starts in row 1.
