It's rust and I did a bad job of version control and eventually broke it so I recommend running away from looking at it (as I have done)

my 13 year old daughter was just talking about this the other day, she's excited to work on again... I think this will be year 4 doing it and year 3 doing it together.

... and as usual, I'll be posting the puzzle from the card and a free printable a4 version on my blog in early December so you can wait for that if you don't want physical card ones to give to people.

(don't buy them if you're going to MathsJam Gathering this weekend, as you'll be able to get them there without markup for postage costs.)

Yes, announcement blog post coming soon

Hmm. This is done through ko-fi which I'd expect to be less broken than something I built. Hopefully they fix their issue quickly

Also if you're a member of the Finite Group, have look on Discord before paying for this (!)
