From the people behind the Alan Turing Cryptography Competition.
You are reading the website of the 2018 edition of the MathsBombe, which ended on Saturday 28th April at 11:59 pm
Do you like solving mind-bending mathematical brainteasers?
Can you and your friends untangle some fiendish puzzles?
Would you like the chance to use your mathematical skills to win some great prizes?
Then the MathsBombe is for you!

MathsBombe is aimed at students up to Year 13 (England and Wales), S6 (Scotland), Year 14 (Northern Ireland). You don't need to be a computer whizz or a mathematical genius — you just need to keep your wits about you and be good at solving puzzles! (See here for eligibility.)

What do I have to do and how can I take part?

The competition starts on Wednesday 10th January 2018, and you can register your team (or join an existing team) here. A team consists of at most 4 members. Registration opens on Friday 1st December 2017 (you can request an email reminder on the registration page). See this section for more details.

Every two weeks a new puzzle set will be released. Each puzzle set contains two mathematical puzzles for you and your team to solve. The puzzles span the whole spectrum of mathematics: from fiendish logic puzzles in pure mathematics to applications of mathematics in real-world settings. You'll need to keep your wits about you and `think-outside-the-box': complicated techniques from A-level or computer coding probably won't help you!

There are four puzzle sets in total (so eight puzzles across the competition). Points can be earned by solving each puzzle and submitting your answer. The leaderboard keeps track of how well each team is doing. (See the FAQ for how the scoring works.)

What can I win?

  1. If your team are the first to solve both puzzles in a given puzzle set, then each team member wins £15 in Amazon gift vouchers.
  2. Each member of the teams that finish in first, second and third place on the leaderboard win £30, £25 and £20, respectively, in Amazon gift vouchers, and the teams' schools will win a trophy.
  3. Each chapter also has a number of spot prizes: for each chapter, spot prizes (of £10 Amazon gift vouchers per team member) can be won by up to 3 randomly chosen teams — but you'll have to be fast: spot prizes can only be won before the next puzzle set is released!
(See the FAQ and rules for how the prizes are determined and how they are sent out.)
