This blog post is about a new variation on the classic Quarter the Cross problem, which I call Quarter the Cross: Connect the Dots.
Here is the original Quarter the Cross problem:
To catch you up, here is everything I’ve written about Quarter the Cross up until now:
Quarter the Cross — in which I first learn about […]
I conscripted the game Numbers and Letters seven years ago to help promote the Maths Learning Centre and the Writing Centre at university events like O’Week and Open Day. Ever since then, it has always bothered me how free and easy participation in the Letters game is, while the Numbers game is much less so. […]
This blog post is about a game I invented in February 2020, the third in a suite of Battleships-style games. (The previous two are Which Number Where and Digit Disguises.)
NUMBER NEIGHBOURHOODS: A game of analytic deduction
This game is for two players, or two teams.
Each player/team choose six different numbers between 0 and 10 (not including 0 […]
Quarter the Cross is one of my favourite activities of all time, whether in maths or just life. I learned about it way back in 2015 and have been mildly or very obsessed with it ever since. You can read about my obsession in my first Quarter the Cross blog post, and you can read […]
Last year I invented a game called Digit Disguises and it has become a regular feature at One Hundred Factorial and other events. But before Digit Disguises came along, there was another game with a similar style of interaction that we played regularly, and this blog post is about that game. The game is called “Which […]

The weekly puzzle session that I run at the University of Adelaide is called One Hundred Factorial. In the middle of the night, I suddenly realised that I have never written about why it is called One Hundred Factorial, and so here is the story.
The very beginning
Once upon a time I was a PhD student in […]
This blog post is about a game I invented this week, and the game is AWESOME, if I do say myself.
DIGIT DISGUISES: A game of algebraic deduction
This game is designed for two players, or two teams.
Each player/team has two grids with the letters A to J, one labelled MINE and one labelled THEIRS, like the […]
While I am thinking about SET, it is high time I wrote about a version of the game SET that was invented at One Hundred Factorial back in 2017, but has never been recorded anywhere for posterity. It is prosaically named Team SET.
In case you don’t yet know, the game SET is a game of visual […]
Amie Albrecht recently posted a most wonderful blog post about SET, and it reminded me there were some SET-related things I should post too.
The first is this little reflection on how I go about teaching people to play SET. Amie talks here about a very excellent way to do this, which is to get people […]
