The Xmas Puzzles 2025 is now live — 13 fiendish puzzles and a “metapuzzle” that draws on their solutions. The competition will run until 20:00 GMT on January 18.

Quizmaster Tim Paulden has pledged just over £1000 in charitable donations as prizes. The top four entries will win a donation to a charity or good cause nominated by the solver: £200 for first place, £150 for second, £120 for third, and £90 for fourth. Those who solve the metapuzzle or score 50 percent or more will also win a donation.

Entry is free and open to all — participants can work alone or in teams of up to five people. Details are at the link above.
