Questions

Q: Do you need the Internet to solve the cases?Asked by Zayani M., June 2019

Hi Zayani,
Since you work with the detective via email, you do need an Internet connection as well as an email account. Some cases also include websites that you'll have to visit. That said, you will never need to use Google or any other web resource that isn't a part of the case.

Q: Is each month a case that can be solved without the next box? There is another subscription that is similar and you have to get 6 boxes to be able to solve the case.Asked by Shelly G., September 2019

Hi Shelly,
That's a great question - thank you for asking!
All of our cases are stand-alone, so you'll get a new, independent mystery to solve each month.

Q: The description says it spans over 4 case files and that the subscription ends after 4 months. However could you do only one of the four months as a stand alone case or is you need all four files?Asked by Krystiana I., May 2021

Sleuth Kings answered...May 2021

Hi Krystiana,
Thanks for reaching out.
While our subscription cases do involve an overarching story, each case is its own, stand-alone mystery. If you decide that you'd only like to try one month, that's no problem at all.
Thanks!
Brandon

Q: I want to give this as a gift but want to designate a finite time. Do you offer that or do I have to sign up and then remember to cancel when the "gift" is over?Asked by Sharon S., December 2020

Sleuth Kings answered...December 2020

Hi Sharon,
Thanks for reaching out!
Our subscription options are set to last 4 months and then automatically end. While the subscription cases make up a 4-part series, each case is also its own complete mystery, so you can cancel at any time without worrying about your gift recipient being able to complete the mystery.
Currently, to my knowledge Cratejoy does not offer the ability for you to purchase a subscription with a customized end date, which means you would need to cancel your subscription if you'd like to send your recipient fewer than our 4 cases. Alternatively, we do sell our past cases in the "Archives" section of our website. Those may be a better option for you if you'd like to purchase a specific number of...

Thanks, I didn't realize this was USPS' fault. I'm sorry you've had trouble with a bunch of your shipments, I hope USPS gets that sorted out soon.
Anyway, I deleted my review and will update once I get the box. Thanks for sending a replacement!

Hi Joseph,
I truly do apologize for the USPS shipping issue. As I mentioned in the email I sent to everyone last week, I've been on the phone with USPS multiple times, emailed with them, and visited the post office where we ship things from. Unfortunately, the information we've been given is that due to COVID and increased holiday shipping volume, USPS is experiencing significant delays. We were told that the packages are likely held up in Columbus, OH but that they hoped to be caught up soon.
I have spoken with USPS since my last update, but they have been unable to provide me with any additional information. I've also submitted information to open an investigation once enough time had passed, but have yet to hear...

We found that some of the clues and help from the emails was incorrect. This was our first box. We are going to give another shot next month.

Hi Christy,
Thanks for your feedback. I'm sorry to hear you did not enjoy your first case. We do have multiple people extensively test our cases for errors but, if you found one, I would love additional information about it so that we can take care of it.
It does look like you signed up for our Master Detective series. If the case itself was too difficult, we do offer a Rookie Detective series that may be a better starting point. The Rookie Detective's story involves time travel and is a lot of fun, so it may be exactly what you're looking for!

Loved it, so much fun!

My husband and I wanted an activity to do with our fourteen year old son. He loved and we loved it!! It was so much fun figure it out the clues and email the detective. The clues were challenging but not to the point of frustration. It took us two days to solve and we are excitedly waiting for our next case!

Fun puzzles and interesting stories

I’ve tried quite a few “mystery boxes” and Sleuth Kings’ definitely at the top. The stories are great and the puzzles are challenging and fun...if you ever need help Sully’s always there for you. The e-mail exchanges with Sullivan are what makes this box unique. We’ve gotten close enough where he doesn’t threaten violence when I call him Nancy Drew. Or Holmes. Or Sugar Britches. 10% of the fun is coming up with absurd nicknames for Sullivan.
If you like single box closure and intriguing stories this ones worth a try. I know I’m hooked. I just need to figure out my plan to work through all the archived cases. 😁

Excellent Puzzle Box

It's taken me too long to write a review, since I've been subscribed for so long now, but this is my favorite subscription box by far! I always have a great time trying to solve each month's case with family and friends, and the "interactive" element with Sullivan adds a fun immersive twist to the experience. Cases could probably be solved alone, but it's a lot of fun to work with others. I really like that some cases have callbacks to previously encountered characters or events, and that the puzzles and clues are always fresh and different. Sometimes the difficulty of the puzzles can vary from month to month, but there's a good hint system built into the box, and the team behind Sleuth Kings is very helpful and responsive. I was missing something in a box once and the issue was solved quickly and professionally. I also appreciate that if you're on a month-by-month plan you can skip a renewal if needed without otherwise adjusting your subscription. Overall, a fantastic experience that you should try if given the chance!!

So this was our first mystery subscription and the experience has been terrific. I ordered one case just to try it out first; received the case quickly and Detective Sullivan was always quick with a reply to help when we asked for it. Signed up for the subscription and we completed the second case on our own. So there are varying levels of challenges, which is great to keep things different each time. The packages have been well made, complete, and very detailed. If you are looking for a new activity this is a great subscription to try.

Just received my second box. I can’t tell you how fun these are. My husband and I love working through these. They challenge both of us. We will take breaks and then one of us will shout I think I know what to do. Really good bonding time for us.
