Great experience

I ordered an EXIT game off of Amazon and one of the pieces of the puzzle was missing. It was the first time this has happened after years of playing the game, so I have contacted the customer service website and they replied in such a quick manner and even offered to replace the part!

Structural Engineering

Structural Engineering - Bridges and Skyscrapers is a brilliant product which gives an excellent insight into the maths and physics needed for these structures as well as providing practical experience in building them.
Nik was super helpful in sorting out some missing parts to our set, which has been well loved for over 5 years and is still going strong.

I purchased one of the company's games, which was missing some components. When I contacted the company, their response was prompt and they were very helpful in establishing what was missing.

Fantastic advent calendar

Fantastic advent calendar, so much more than a simple chocolate one and so much more fun. We were all looking forward to opening the next day. Very cleverly put together, can’t praise it enough.

6 stars if I could.

We have the Andor family fantasy game and LOVE IT!! The team work I see my kids show while playing this game is fantastic. They encourage, make decisions together and have loads of fun trying to win the game.

It is the best game we’ve played so far and excited to try other cooperative games

Phenomenal customer service

I lost the instructions for one their advent calendars three years ago, and it has sat taunting me ever since. I finally got round to emailing to ask if they could possibly send me a digital copy and they immediately sent out a physical copy. They were obviously under no obligation to help me at all (entirely my fault, and so late after the purchase). Fantastic, speedy customer service. I am thrilled!

The calendar advertised as being in English is… in German.

We ordered the calendar in October, the English version, to do it as a family. When we opened it today, December 1st, although the calendar itself is in English, the two booklets that are required are in German. That was an unpleasant surprise, and of course the website Amazon sends us to for filing a claim and explaining the problem doesn’t work! (The captcha doesn’t work).
after finding an email: we received the booklets in English as PDFs. Great. We open the first box… all the clues are in German. So after printing around 50 pages ourselves, it’s still unusable.Offering the calendars in English is great, but everything needs to be in English, otherwise it’s misleading advertising…

High praise Thames and Kosmos.

I cannot praise Thames and Kosmos to highly after they dealt with my question. I sent a question in to them about Gecko Bot 2.0 which was sold out everywhere and I needed to replace after it was stolen in break in. I asked if it would be restocked or where I could get one and had an answer within the hour. Jane who answered my question was so helpful and sorted out the problem within 2 hours of the initial inquiry. I cannot praise Jane enough, Friendly, efficient and helpful above and beyond her duty Jane is a credit to the company.

Silent Storm Advent Calendar

I bought the Silent Storm Calendar for my family, and this is the best Advent we've ever had! It unites the Family in solving the puzzles. The puzzles are not super easy and are not hard to be discouraging - just enough to spend 10 minutes reading the story, thinking of the solution and checking versions. We had a Story Book missing but the 'Thames and Kosmos' team sent it to us within 24 hrs - so we didn't miss anything and are now fully enjoying the experience.

Wonderful customer service

We had an issue with our "Exit the Game Advent Calendar" where we were missing the story book. I contacted Thames and Kosmos and had a response within 12 hours with a pdf of the book so we could start the advent calendar on time, which was a great relief to my 10 year old! I was very impressed with the quick response and fix. Thank you Nik for your help!

I purchased the roller coaster game from a charity shop for my grandson but unfortunately the cars were missing. I contacted the company and within minutes Jane answered me and dealt with the query so proficiently that I was amazed at the service I got from her. The missing cars are now on their way to me. This company excels itself in customer satisfaction and I cannot thank Jane enough for sorting this, well done Thames and Kosmos.
