NEWS The new challenge for 2013-2014 starts with a BANG! Maybe a little crash too... (oooops), but it's now in full swing!
This monthly challenge has five levels - the latest entry level question is shown above. You can use whatever means you like to solve the problems, just type your answer in the box and click Submit. If your answer is correct, you will progress to the next level. If you correctly solve all five levels, you will appear on the C3L6 Honours Board. New challenges will be released at 00:00:01 (UK time) on the first day of each month for November to June. Will you be the first person from your school, your town, your country, or even the first person in the WORLD to complete it? You have one month to try and make it on the honours board.
All the previous challenge are now available in the Online Challenge Archive, together with their honours boards. You can access these by clicking on "The Online Challenge" link below. For those of you who got stuck, the HINT and ANSWER functions now work, just type these into the entry box; typing HINT will give you some help to answer the question; typing ANSWER will give you the answer, leading you to the page with the fully explained solution. These functions will NOT be available on the current challenge!
