Suddenly your nan's Sudoku is something you wish you'd mastered at least once, as this is the brain-training needed to be able to Escape the Room.

Crack the clues and get the key to freedom but remember the clock is ticking.
Who's good at numbers, words, lateral thinking? Oh, you could be there til the bitter end then … or forever!
