The last set created, the Riddles of Riddles Recharged brings a new life to this collection of 380 Riddles. The answers to this 50-Riddle set are somewhat interesting facts regarding topics such as the solar system, ancient "times", comparisons between several specific measurements, and multiple codes and patterns. This is also the first set with a text-in box, thus allowing those with multiple correct answers to advance to the next Riddle.
