Unlock Your Mind: The Ultimate Book of Riddles and Brainteasers

Design a book cover titled 'The Ultimate Book of Riddles and Brainteasers'. The cover should have a bright orange background with black and white elements. Include various icons such as a lightbulb, puzzle pieces, a magnifying glass, a clock, gears, an hourglass, a compass, a pencil, a brain, and a key. The title should be in large, bold letters and curved around a large black question mark in the center. Add the text 'A Selection of 222 Brain Puzzles, Teasers, and Riddles for All Ages' at the top. At the bottom, include the subtitle 'For Adults and Kids' and the author's name, 'A.C. Brooker'. Ensure the design is playful and engaging, suitable for both adults and kids.
