Around 100 'Speedcubers' from nine countries are competing in the UK Open 2012 Speedcubing Championship this weekend at the University of Leicester.
The event was co-organised by second year Mathematics student Laurence Livsey, who also set up the University of Leicester's first Speedcubing Society this year.
Laurence succeeded in getting backing from international speedcubing authority the World Cube Association (WCA), meaning that all winning scores – including any new world records set – will be official.
A machine on display at the Speedcubing Championship at the University of Leicester, is able to solve the Rubik's Cube puzzle in less than five seconds.
The video below shows the gadget, strapped to a mobile phone, solving the Cube in 4.89 seconds.
