Great way to spend an evening in!
Good challenging mysteries. Not completely obvious and a good brain-teasing alternative for date night. 3-4 hours of mystery solving involved. Ordered 1 and then ordered more. Shared them out with the fam too - hope to do one at the next family games night.

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),

Extremely well constructed crime puzzle!
Great fun! Really well put together. Played it as a family and took a team effort to solve. Highly recommend these puzzles! Kept the TV off for two evenings!

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

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.

Stunning way to spend a few hours and get the brain working
Stunning case file, really took hard graft to get to the killer. Highly recommend giving it a go.

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.

My partner and I (both in our early 30s) enjoy doing these sorts of murder mystery packages together for date nights, and this was our first "Cryptic Killers" box. We really enjoyed it! The story was fun and I liked the mix of some puzzles with a lot of logical thinking and piecing things together. We talked through a lot of stuff together, which is always fun when you're doing these as a pair/group. We also thought everything was fair -- no wide leaps in logic or any guessing games were needed on our end. Everything made sense when we connected the right clues together. The documents were also well-made overall (some typos here and there, but nothing major) and high-quality. We read through everything and this ended up taking us a few hours over a couple of nights, so it was totally worth the money. The ONLY thing is we would have loved it if it was all on paper with no real online elements -- this game has a few online clues/pieces of evidence and we didn't have a laptop with us when we did it, so we were having to read them on our phones. It wasn't a huge deal, and mostly a personal preference. We'll be getting more of these in the future for sure!

Fabulous fun game

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.
