There are over 200 questions in total, many of them more challenging than the example listed above. You are given several clues to help solve the riddles, such as the letter count per word. Still, it may very well happen that you are unable to solve a riddle. This is where the coins come into play. Collect them as you go (you are awarded three coins per solved riddle), and should you ever get stuck you can use them to buy your way out of the tight corner.
