The Billionaire's Inheritance: A Passcode Mystery Puzzle Book

A billionaire is dead. You could be the heir to his fortune. There are 28,000 possible passcodes. Can you eliminate the wrong passcodes until only the right one remains? This immersive puzzle book celebrates slow thinking, careful observation, and the quiet satisfaction of logical deduction.

A bestselling mystery novelist has died, leaving behind his fortune and a final mystery to solve. His millions are tucked in a locked safe and he’s left a list of clues to the code that will open it along with 28,000 possible codes. Only one is correct.

You won't need any math skills or specialized knowledge to solve this puzzle—just careful observation, logical thinking, and the curiosity to keep going.

• Follow the clues: Each one narrows the field, limiting the possible correct answers until only one remains. Some depend on the digits themselves while others refer to where the number appears.
• Eliminate wrong answers: Using the clues, narrow down the possible answers and discard the codes that won’t work.
• Find the code: Once you’ve gone through all the clues, only one correct answer should remain.

Along the way, you may find famous dates, interesting patterns, and other hidden Easter eggs. They won't reveal the winning code, but they'll reward those who pay attention. But keep your eyes on the prize. There's only one right answer—and though the fortune may be fictional, the triumph of cracking the code is entirely yours.
