<mdoxml version="1.0">The <a href="http://nrich.maths.org/thismonth/all/2012/02">February 2012</a> problems are all on the theme of codes and codebreaking, in celebration of Alan Turing's centenary.
<p>Instead of featuring a game this month, we have invited James Grime of the <a href="http://enigma.maths.org">Enigma Project</a> to create a code challenge.</p>
<p>You can watch the video here or visit James's <a href="http://www.youtube.com/user/singingbanana">YouTube channel</a> and watch it there.</p>
