The MathsJam annual conference is a magical time when maths geeks converge on a conference centre in the middle of nowhere near Stone and spend a weekend sharing their favourite puzzles, games, and mind-blowing maths facts.

Registration for the 2015 weekend, taking place on 6-7 November, has now been opened. More information about the conference, and how to register, can be found on the MathsJam Conference website.

We’ll all be there: join us!

First Clay Award for Dissemination of Mathematical Knowledge goes to Etienne Ghys

The Clay Mathematics Institute is best known for handing out a cool million in return for answering a hard question, much like Chris Tarrant.

Anyway, that’s not all they do! The Institute says it is “dedicated to increasing and disseminating mathematical knowledge”, and that now includes handing out an award for Dissemination of Mathematical Knowledge. The first recipient is research mathematician, Frenchman, and all-round top chap Etienne Ghys.

I’ve made my own numbers-in-a-grid game

For the past couple of weeks, I’ve been obsessively playing the game Twenty on my phone. The fact that my wife has consistently been ahead of my high scores has nothing to do with it.

The main source of strife in my marriage.

Twenty is another in the current spate of “numbers-in-a-grid” games that also includes Threes, 10242048 (and its $2^{48}$ clones), Just Get 10, and Quento.

The basic idea is that you have a grid of numbered tiles, and you combine them to build up your score. While there are lots of unimaginative derivatives of the bigger games, there’s a surprisingly large range of different games following this template.

With so many different games being created, I thought that a chap like me should be able to come up with a numbers-in-a-grid game of my own. Yet, for a long time, I just couldn’t come up with anything that was any good.

Yesterday I had a really nice shower, and the accompanying feeling that I’d come up with a really good idea – make a game to do with arithmetic progressions.
