Instructions
Examine the casket to receive a hint about the two-digit code. For example, you might be told that the second digit is even, or that the code is between 15 and 35.
Repeat the examination until you have enough clues to get a rough idea about the code. For example, if you know the code is between 15 and 35, the first digit is even and one of the two numbers is 3, it follows logically that the code is 23.
Attempt to enter the correct code. If you are incorrect, you will be informed that the number is higher or lower. Try again until the casket is unlocked.
