3900. Mininigma

We’ve got my grandson today and he wants to do coding on Roblox and some texting using this app. It’s called Mininigma and it emulates the WW2 Enigma machines from Bletchley Park. I’ve forgotten how to use it but I’m hoping my son hasn’t as I’d like him to put it on his phone too! I think we can get an Android version so we will try it out and my grandson can text his Uncle as well as his Granny!
