coverOn Friday I posted this puzzle….

A very different type of puzzle this week… do you understand why this is correct…..

If you have not tried to solve it, have a go now.  For everyone else the answer is after the break.
You simply have to mirror the left hand digit and move it over to the right hand digit!  Did you solve it?
I have produced an ebook containing 101 of the previous Friday Puzzles! It is called PUZZLED and is available for the Kindle (UK here and USA here) and on the iBookstore (UK here in the USA here). You can try 101 of the puzzles for free here.


  1. The first one is a bit iffy. It’s more like a “heart symbol balance on a line” than a fish.

    As for the answer, I guessed as much based on “eight” and “triangle”.

    1. ah, thanks Darek!
      It didn’t occur to me that that’s exactly what I was doing with the 3s. Though if you apply the same method to the 7s, the triangle has tails, but that’s just being picky.

  2. Someone mentioned fonts on Friday. It was the first time that it had occurred to me that the puzzles might display in different fonts on different machines. The three examples work fine in my display, which was why this was a nice easy puzzzle.

    1. As it’s a bit image, it will appear the same on all devices.

      nb. the 2+2 problem is a little fishy – in that an adjacent mirror image doesn’t look much like accepted symbol for a fish which usually has a pointed “nose”, not an inversion. However, it’s the same for everybody.

  3. I like this puzzle but wonder about the use of the equals sign. Is there a better way to state the problem without essentially using the equals sign wrongly? I guess an approximately equal to sign would work. Other ideas? Am I being too obstinately Mathematical?
