from 289 reviewsOur group had a great time doing this - the host definitely needs to spend some time getting to know the game to make sure it runs smoothly but that is expected with a murder mystery! Would highly recommend :)
We haven’t played the game yet but it looks and sounds promising!
Costumer Service was top notch, answered my questions on the same day and were very nice.
Thanks!
I did this murder mystery for my 30th and it was so much fun! I actually had more than 20 people plan to come, so I reached out the the GrimmSisters and they sent me extra copies of character sheets to help me out! They responded very quickly and had amazing customer service. I definitely recommend!!
We had so much fun playing for my salon Christmas party! Easy to understand and everyone loved it!
This came instantly as a download and is so clear to understand and navigate. I cannot wait to host this mystery dinner :)
Such a fun theme and I had to put in no effort to host a great party!
our entire party loved this game it was so easy to use and so much fun would def. purchase from this shop again
This is the 4th murder mystery party we’ve bought by these sellers and it was a load of fun. There’s a ton of potential in this game to really make the most of it. We had a bbq with lawn games, a bracelet making station, Polaroid photos, etc. to really emulate a summer camp experience. After supper, we played the game, and then we had a bonfire.
The characters for this game were fun, punny, and 80s themed which was a real delight. Such a fun experience and my friends all had a blast. We had people present who had done 5 murder mystery parties and people who had done none; so there was a real range, and it was beginner friendly while not being boring. Looking forward to buying another game from the sisters in the future!
Perfect game and theming for our Halloween Party. They thought of everything. Quick and easy access. All the materials needed are printed out at your home. There is a step by step guide that helps with planning and running the show that night. Once you see all the materials, it is easy to follow. I had a question and the sistersgrimm responded right away with helpful ideas. You will not be disappointed.

Was a fun murder mystery played with seven people. Went wayyyyy faster than I expected!
