Some things take time: H5P Crossword

Some things take time. Have a look at this request on the H5P forum for example: farrisimin wished for a word search puzzle and a crossword puzzle back in 2015. Last year, one of his wishes was granted. Jithin Thankachan contributed Find the Words to the pool of H5P content types. But what about a crossword puzzle? Well, there’s only so much that software developers can do in their free time. But what if someone funded some of the work that’s required to build such a content type for H5P?

Enter LTC, a company in Hamburg, Germany that did just that. But not just that! They also want to share the result with the H5P community. Guess what, here it is! You will have to wait a little before the H5P core team finds some time to review and release H5P Crossword to the H5P Hub. However, feel free to download the demo content from this page and to upload it to your platform in order to install the required library. Please note: An admin will have to do that for you if you lack the rights to manage H5P libraries.

Features in a nutshell

  • Allows you to create a pool of clues and words that will be used to generate random crosswords or have the words at fixed positions
  • Is not limited to using A-Z, but uses uppercase characters only
  • Allows you to optionally use a background image
  • Allows you to add a special solution word
  • Provides you with an option to add extra clues: text, image, audio or video
  • Adjusts the layout based on the horizontal space given
  • Supports xAPI, e.g. for transferring results to a host system’s gradebook
  • Supports saving and restoring the current state (if activated in the H5P plugin settings)
  • Has keyboard support on the grid and additional text input fields for improved accessibility
  • Supports readspeakers (fairly well)
  • Has an optional instant feedback mode and the usual H5P views for results and the solution

Some more insight

I already demonstrated a beta version recently during my monthly live stream on twitch. I am pretty sure that I explained some of the things that I just mentioned briefly 🙂

Future development

The future development of H5P Crossword is not set in stone. If you have any ideas for improving the content type, please leave a comment or rather get in touch with LTC directly – as I mentioned, this was contract work. But please be aware that the development will depend on the availability of resources (free time and/or funding). Speaking of resources … You can find the source code on github and do changes yourself.

  1. Hi Oliver. Thanks for sharing this crossword puzzle. It looks awesome! In your live stream on Twitch last night which I couldn’t attend but watched the recording after, you mentioned installing it to try it out! I wonder how I could do that? I can’t install on either my or accounts as yet so how would you recommend going about this for the purpose of trying/testing out content types that haven’t been officially released yet! Could this also be on your list for doing a short video on this very topic? Best regards, Ben

    1. Hi Ben!

      The answer is simple: You cannot install new content types on or That needs to be done by Joubel. You’ll have to use a self-hosted platform like WordPress or Drupal, or you can try it on Lumi (

      1. Yes. Thanks Oliver. I will try Lumi. I also have a self hosted Moodle instance so would I be able to install this crossword there? Again I think it might not work because I would have to first install the library for this content type I am assuming ?

        1. Hi Ben!

          H5P content files always contain all libraries that are needed to run the content, and if the user who tries to upload the file has the necessary privileges to manage H5P libraries, H5P will install missing libraries from the content file.

  2. This crossword puzzle will be a great add on for H5P! Kudos!
    A feature I’ve always been waiting for in crossword puzzles is the ability to use images as the clues instead of text.
    If that can be a feature it would increase the applications for graphic based topics as well (I teach music!)

    1. Hi Khew!

      Thanks. Noticed the info symbols behind the clue? That’s where you can already add images, videos and audios.


  3. Nice h5p acivity. There is just something that trouble me : you choose the color blue to highlight the associated hint below the grid, but this color blue is very very close to the color when you select a text in a browser. So it look like the text is selected when it’s just a simple highlight. Maybe change the color ?

    1. Hi!

      Thanks for your feedback!

      There are a couple of things that get highlighted and I am not sure what you are referring to. The blue is the standard H5P blue that’s used for buttons, etc., and I am not sure where you might mistake it for highlighted text. However, the H5P core team will give the content type a UX review anyway, so I’ll put it on the list of things that I am not sure of.

      By the way: You can, of course, re-style H5P Crossword like any other H5P content type if you prefer a different design.


  4. Thanks! I was already suspecting the highlighting of the clue label, but I wasn’t sure (as not all browsers use blue – Brave, for instance, that I use, uses red). My previous answer still holds: It’s the Joubel blue, and I’ll wait for the UX review anyway.

  5. Hi, Oliver
    I’m a brazilian public school teacher and I am implementing a wordpress self hosted site with h5p activities for my students.
    How can I install your library in my site?
    I have h5p wordpress plugin installed with all other official libraries installed.

    1. Hi! As mentioned in the post: “However, feel free to download the demo content from this page and to upload it to your platform in order to install the required library.” You can download H5P content – as usual – via the Reuse button.
