The Lottery Killer: An Immersive Murder Mystery Logic Puzzle
Hints
A NOTE FROM CLARAI did not have much time. But I was careful. Everything you need is in the book, and everything in the book means something. These are the things I wish someone had told me when I started.
— C.P.
Start with the clues that sweepSome of Clara's clues will eliminate hundreds of tickets in a single pass, entire pages gone in minutes. Work those first. Save the precise, careful clues for when the field is already narrow. You will know the difference when you read them.
Your pencil is your most important toolCross out decisively. A ticket eliminated by any single clue is gone permanently; do not second-guess yourself. The book only reveals its answer to someone willing to commit.
Keep the clues in front of youThe clues can be removed from the book and kept beside you as you work through the book. Clara wrote them to be consulted, not memorised.
The five fields work togetherEach ticket carries five pieces of information. Some clues touch the number. Some touch the time. Some touch the zone. A ticket that survives one clue may fall to the next. Trust the process; the funnel works.
When very few tickets remain, slow downThe last survivors deserve careful attention. At that point, you are no longer eliminating; you are reading. Look at what remains and think about what it means.
The answer is not just in the dataClara left more than numbers. When the book has told you everything it can, go back to the beginning. She was precise about everything, including the details she mentioned almost in passing.

Frequently Asked Questions
The puzzle book has reached more people than I expected. These are the questions that keep arriving. I have answered them as honestly as I can.— Clara
Does the book include the solution?No. The solution was never mine to put in a book. If you have worked through the book and applied every clue, submit your answer on this page. If you are right, you will find out what I found and what the police chose to ignore.
Do I have to apply the clues in order?No. Each clue works independently; a ticket that fails any single clue is eliminated regardless of when you apply it. That said, the order Clara chose is not arbitrary. It was designed to narrow the field gradually and make each elimination feel meaningful. First-time solvers are encouraged to follow her sequence.
I have applied all fifteen clues and have no tickets remaining. What went wrong?One of two things: either a clue was applied too broadly and eliminated tickets it should not have, or a clue was applied to the wrong field. Return to the clues in order and check each one carefully.
Does the purchase time include the colon?No. For clues involving time digits, treat the time as four individual digits, hour and minute together, no colon, no separator. 21:13 is 2, 1, 1, 3.
Is a digital version of the book available?This case-solving requires a physical book. The puzzle is built around crossing out tickets with a pencil across hundreds of pages. A digital version is not currently available. Clara would probably say the data deserves better than a screen.
I submitted an answer and it was wrong. Can I get a hint?Yes. The hints page will help you without giving anything away. Work through the levels one at a time. Clara designed the clues to be solvable, not to defeat you.
Can I work through the book with someone else?Absolutely. The register is the same for every reader. The puzzle does not change. Working with a partner means you can divide the chapters between you and compare results. Just make sure you both apply every clue to every chapter before drawing conclusions.
I think I have found a duplicate ticket number. Is that an error?Every ticket number in the register is unique across all seven chapters. If you believe you have found a duplicate, check the numbers carefully; five-digit numbers that look similar are rarely identical. If you are certain, please contact us, and we will investigate.
Do I need to refresh the page to try another answer?Yes. If your ticket number is incorrect and you would like to submit another guess, refresh the page and complete the verification form again.
Will there be a second book?Clara has more envelopes.

Clues
The clues below are the revised clues included in the Second Edition of The Lottery Killer. They have been refined to create a more challenging and satisfying elimination experience.If the opening page of your copy does not state “Second Edition,” you have the original First Edition. Your book contains a different version of the clues, and you can still solve the mystery using those clues as printed.However, if you would like to try the updated challenge, you can use the revised clues provided below while working through the lottery register in your existing copy.
CLUE 1: The colour did not belong to night. Nor to shadow.
Cross out every ticket where COLOUR reads Yellow.
CLUE 2: The far booth was noise. Nothing of value came from that wall.
Cross out every ticket purchased at Booth B8.
CLUE 3: The last minutes of the hour lead nowhere. Whatever was done was done before the clock reached its end.
Cross out every ticket purchased from minute 51 to minute 59 of any hour, inclusive.
CLUE 4: One ending was too neat. A minute that ends cleanly in one is not a minute of chaos.
Cross out every ticket where the purchase minute ends in 1.
CLUE 5: The garden was loud too early. Open air, first half of the hour. Someone still finding themselves.
Cross out every Garden ticket purchased from minute 00 to minute 29 of any hour, inclusive.
CLUE 6: The second booth gave only static.
Cross out every ticket purchased at Booth B2.
CLUE 7: The centre was not marked with four. The middle digit is where a number commits.
Cross out every ticket whose middle digit is 4.
CLUE 8: The ending did not echo the minute.
Cross out every ticket where the final digit of the purchase minute is the same as the final digit of the TICKET #.Example: A ticket bought at 21:47 with a TICKET # ending in 7 would be crossed out.
CLUE 9: The ending did not belong to the booth.
Cross out every ticket where the final digit of the TICKET # is the same as the booth number.Example: A ticket bought at B5 with a TICKET # ending in 5 would be crossed out.
CLUE 10: Five strangers never shared the truth. A number with no repetition has no loyalty. It belongs to no one.
Cross out every ticket whose TICKET # contains five different digits.
CLUE 11: The ending did not mirror the fourth mark.
Cross out every ticket where the fourth digit and final digit of the TICKET # are the same.
CLUE 12: The number did not begin in all even marks.
Cross out every ticket where the first three digits of the TICKET # are all even.
CLUE 13: The seat number did not echo twice. A position in the room, written into the ticket. Once is information. Twice is a signature. This number did not sign itself that way.
Cross out every ticket where the zone rank appears exactly twice in the TICKET #.Use the zone rank already given in the reference section at the back of the book.
CLUE 14: The number was not almost heavy. Not in the range where numbers lean too close to the top.
Cross out every ticket whose five TICKET # digits add up to 26, 27, 28, or 29.
Open this final clue only after Clara’s fourteen clues have been applied.If you have followed Clara’s fourteen clues carefully, more than one ticket may still remain. That is expected. Clara did not place the last instruction with the others because, used too early, it would distort the investigation. Used last, it closes the case.

The third mark returned three times and ended on seven. The killer’s number carried the same mark again and again. Then it closed with a final seven.
Cross out every ticket where the digit 3 does not appear exactly three times inside the TICKET #.Then cross out every remaining ticket whose TICKET # does not end in 7.
