• This is a challenge designed to be repeated. The most important thing is not to despair. You can do it! Even the brightest among you may have to go back 16 times. You will probably need paper or another window to write down your discoveries! First find the value for each of the four challenge numbers. When you have all four, select the correct code. Your challenge numbers are: 11, 30, 59, and 89. Good luck, codebreaker!
