Whoa this is nice, i calculated 13.

Yeah! I got thirteen too. But the eighth one was a bit hard to find. It took me three recounts, and a suspension I was missing something obvious to finally see the solution.

I’m getting 14. The one hidden on the number 4.

13?

You're right - 14.

I missed that three on the number four button too.

Yes. There are 14!
