Satisfying to solve - recommend
Brilliant. Single player, played over a few small sessions over 2 weeks. Great story. Satisfying to solve. Works out well. Have bought another. (Found a poly-pocket book useful for evidence and took notes as went along),

Great game!
I loved playing this game, the clues and the materials were all really good, nice couple of hours spent playing it. Easy to use and to check for clues and answers online. Recommended!

Fun for all, especially teenagers
What a great game!! Purchased for a family games night and it lasted for hours. We were able to discuss the evidence and only when we reviewed it all did we compare our notes to the hints did we see we had been on the money for the most part. Will be definitely purchasing another one for a future games night.

Good date night activity
Enjoyed this as date night. We have done a couple and they are a wonderful way to spend the evening. I would say this wasnt my favourite that we have done, some of the puzzles felt unproportionally difficult to how useful they were, aka took us half an hour to solve one bit, and we didnt even need it. This made it feel slightly less satisfying

Fun , puzzle to solve.
The case was intriguing and took us 3 hours to complete. We enjoyed solving the case as a couple and will be doing another.

Fantastic Family activity
Originally brought for myself, but soon become a family event. Incredibly interesting, and loved how much evidence and material was included in the packages. Easily understood the instructions, as well as the online aspect of evidence and hints. Great value for money!

Fishy Murders
Had a blast solving this mystery! It took us the recommended amount of hours to finish it, but it was so engaging you couldn't stop. The time just flew by because we didn't want to stop and lose our traction. The pack provided (and the packaging looked super nice) had so much information in it from different parts of the investigation process which made it all the more fun. Would absolutely recommend this game to others, excellent work by the creators!

Made for a great, at home, date event. Hubby and I spent about 4 hours total (Part 1 on Saturday night, Part 2 on Sunday night) solving this murder. We've used similar games before, first time buying from Cryptic Killers. Will definitely purchase another one. Was challenging and fun!

Super fun. Well thought out. Engaging and actually makes you think and collaborate with your fellow detectives. Pay attention! Details matter. Will definitely play again.

If you ever played game of this sort you will be heavily dissapointed. The case file consists only of 2 folders with paper hints, nothing much else. The riddle is written very poorly, and the main difficulty is not in solving it but undertanding what the creator had in mind. I agree with other people being dissapointed in the clues not leading you in an organised way to a conclusion - after all you have only 2 tasks. Only will give one extra star for the print quality, as it wasnt bad at all, but its only because it wasnt terrible. Will definitely not buy any more games from this author as its very dissapointing - 'detective for a day' stories are much much better.

Great game for a group. We haven't played this kind of game before and we really enjoyed it. Have to think and read a lot of clues and try to eliminate suspects.

Hours of fun. Challenging. Didn't need to use any hints but it was close! Would definitely buy another one to solve.
