Puzzle Battles are a series of battles against Dimitri Allen and Clive found in Professor Layton and the Unwound Future. The first is found in the Gilded 7 Casino when Professor Layton is challenged by Clive to prove that he is not in disguise. The second is found at the top of the Towering Pagoda when Dimitri Allen's true identity is revealed along with Bill Hawks' whereabouts. The third is found in the Thames Arms when Dimitri Allen threatens to blow the Thames Arms up, this turns out to be not the case. Puzzle Battle 3 is different from the US version in the UK version. Instead of spelling out LIE upside down, it is the symbol of infinity.
