    Kids ages 13 - 17 Really Enjoyed the Game

    Posted by Kelly Terrell on Feb 6th 2023

    I had a group of 24 students, ages 13 up to 17 and they really enjoyed the game. Admittedly, only one person was able to identify the correct solution but what a blast they had! The material was easy to prep and it was also easy for me to not "spoil" it for myself as I didn't want to be biased in the roles that I assigned. It did take them a bit to get the hang of it and I know if I do it again, my instructions will be a bit more clear but great fun for everyone involved. We did not do any additional games and it did take us 3 hours and that included a sit down dinner. We will definitely do something like this again!

    Makes for a fun party!

    Posted by Callie on Nov 8th 2021

    This murder mystery made our party really fun! I was worried at first about participation, but very soon everyone was very into their characters. There were also a lot of fun surprises as the story came out. I opted to download the content and fix it up by myself and was careful to not read the spoiler content. I was able to join without knowing anything! Would definitely recommend! :)

    So much fun!

    Posted by Rachel on Apr 3rd 2021

    We purchased this for my daughter’s 16th birthday party and the kids all loved it! We had 14 teenagers in all and they really got into it and had a good time solving the mystery. The game instructions were very detailed and all the print outs were easy to prepare. It takes a lot of prep work and we did a whole dinner to go along but it was such a fun and memorable birthday party. I highly recommend trying a mystery party!

    Baker Street Murder MASTERCLASS!

    Posted by Hannah on Dec 15th 2020

    I hosted this Mystery Party for my Year 11 (16-17 year old) English class who are studying Sherlock Holmes by Arthur Conan Doyle at the moment. Despite the students being nervous to begin, they quickly got into character and engaged in very intense discussions between characters. The students enjoyed the experience very much, many theories abounded, and there was much excitement about solving the case. This was a brilliant, practical way for my students to engage with the characters and genre of Sherlock Holmes and their enjoyment was commented on around the school as apparently much conversation was had in other classrooms, the library and even on the playground! The resources supplied were excellent and the host package explained everything brilliantly. I would highly recommend this party and Mystery Party in general!

    Lots of fun, tried this virtual, worked ok

    Posted by Unknown on May 17th 2020

    So, we tried this for a virtual birthday party. I sent out everyone's individual part 1, 2, and 3 ahead of time (so it would be nice if the packet was organized this way. I sent out everyone copies of the clues. I asked them to have someone else put it in envelops is possible about 1/2 printed out ahead of time, and others didn't. We had some people dress up in hats, other used snap camera to finish their costume. There were a few things that we should have done ahead of time to make this easier. 1) First, make sure that everyone at the party has either each other's email addresses or phone numbers so they can email and text back and forth. There were parts that were supposed to be a secret from others and we let them be known too soon. 2) Login with your fictional name 3) have everyone login separately - if in the same location - only one person needs to have sound on. Everyone had a great time, even though a few things happened out of order, fun was had by all. ---------------------------------------------------------------- FROM MMP STAFF: This is a face-to-face traditional format game that isn't the format to play online through video chat. We will have conversion kits for virtual play for our most popular games later in 2020, but we recommend playing the virtually formatted games for video chat. We are super glad you made this work for you, though! That is awesome! Thanks for your feedback.

    Good clean fun for a larger group

    Posted by Sherlock on Oct 28th 2019

    This was my first time hosting a mystery party of any kind. I had heard a lot about them but didn't know for sure if my group of friends would enjoy it as much as I hoped they would. They tend to be nerdy and reserved and do well with strategy games but not party games. After the party, however, all of them told me several times how much they enjoyed it! One particularly introverted young man commented that it was like "playing those video games like Zelda where you have to go to different people and see what they have to say." Coming from his background, this was an incredible compliment.
