This blog post is about a game I invented this week, and the game is AWESOME, if I do say myself.

Players:

This game is designed for two players, or two teams.

Setting up:

#### Team SET

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 […]

#### Teaching people to play SET on the fly

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 Back Story

The four fours is a rather famous little puzzle which goes something like this:

#### Numbers and Letters

Since 2013, the MLC and Writing Centre have been doing a game called Letters and Numbers at Orientation Weeks and Open Days to create interaction with people. I tweeted a photo of one of our sessions during Open Day yesterday and it has attracted a lot of attention, so I thought I might record some […]

#### Fairy Bread

Fairy bread, in case you don’t know, is an Australian children’s party food.

Here’s how to make fairy bread: take white bread, spread it with margarine, and sprinkle with hundreds and thousands. Now cut into triangles and serve.

Notes:

#### Home in One Piece: a game of strategy using play dough

This post is about a game I invented called Home in One Piece. I invented it in 2014 specifically to play outside at student barbecues, after years of trying to think of an effective game using play dough. I’ve taken the physical version with me to various places to play it, including to Twitter Math […]

#### Bodyscale Prime Climb
