The next Portsmouth MathsJam is on Tuesday, 17 February, from 7.30 p.m. in the King Street Tavern, Southsea.

Last month we played some games of Set, attempted several geometry problems like this one, discussed the 2015 game, and explored graph theory (that’s what I’m calling it anyway) in the Android puzzle game RGB Express.

As always, feel free to bring along anything maths-related that you find interesting.
