Double Letters Puzzle – ACEHIMNPZ

Usually, my puzzle table features a math-y puzzle of sorts.

This week is different. I’ve chosen a word/letter-based puzzle from Puzzle Box, Volume 2.

I’ve posted plenty of puzzles on my blog from Puzzle Box, Volume 1 and Puzzle Box, Volume 3, so I decided it was finally time to show Volume 2 some love!

Don’t worry, there is still some mathematical reasoning hidden in this double letters puzzle!

You are given nine cards. Each card features a different set of double letters. Your goal is to arrange the nine cards in a line so that a 10-letter word is formed.

Cards can (and must) overlap each other. But, you cannot fully cover, rotate, or flip any of the cards.

Here’s an example of how the letters should be arranged. Keep in mind, the word you will be creating is MUCH longer!

If you figure out this puzzle, please don’t post any spoilers!

These puzzles were created by Serhiy Grabarchuk. I found out while doing some googling as I wrote this post that these puzzles are actually known as “DoubLetters” puzzles.

Serhiy published another one of his DoubLetters puzzles on in February of 2012. You can download a PDF of that puzzle here.

Puzzle Solutions

I intentionally do not make answers to the printable math puzzles I share on my blog available online because I strive to provide learning experiences for my students that are non-google-able. I would like other teachers to be able to use these puzzles in their classrooms as well without the solutions being easily found on the Internet.

However, I do recognize that us teachers are busy people and sometimes need to quickly reference an answer key to see if a student has solved a puzzle correctly or to see if they have interpreted the instructions properly.

If you are a teacher who is using these puzzles in your classroom, please send me an email at with information about what you teach and where you teach. I will be happy to forward an answer key to you.
