Hi there! Thanks so much for using My Worksheet Maker and for your suggestion. We do like the idea of this and we'll look into seeing if there's a way to work it in.

In the meantime, you can still technically achieve this by adding your "free space" image as an item in the Bingo Words section. That way, it will show up in a random place on every card, just like an other image or word.

While not exactly what you requested, hopefully it can be a good work around in the meantime.

Thanks, again, for the suggestion.
