Fancy a free film? We've got 2 pairs of tickets to a preview screening of new Spanish puzzle movie, Fermat's Room, at the Odeon Covent Garden this Thursday night. The film isn't on general release till Friday so consider yourself special if you win. The central quandary sounds a bit like that bit in Star Wars when they're stuck in the waste disposal with the walls closing in except they have to use maths to get out rather than page a helpful droid. Sounds perfect for film buffs, problem solvers and those wishing to put their Spanish to the test (is subtitled for those who don't).
Watch trailer here. To win a pair of tickets simply enter the draw below and tell us what your favourite puzzle is.Winners will be picked at random and notified by email by 5pm tomorrow. You must be over 18 to enter.
