For all of you eagerly awaiting the upcoming Escape from /dev/null developer game in February, we’re arranging a series of weekend algorithmic challenges to get you warmed up!

A weekend challenge works like this; We’ll post a challenge on a Friday and you then have until the Sunday to get coding, find the solution and send in your answer.

The top three decent solutions to the challenge will win a prize, and in addition will secure a seat at the /dev/null developer game early next year - a game that will be played in a multi-user setting together with all other contestants.

So what can you win?

We'll we have a couple of Iain M. Banks boxsets.

There's also a BB-8 robot sitting in its box waiting.

So - Good Luck and Sign Up here!
