Review: 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!
Review: Good family game - We really enjoyed following the clues and working out the solution. Stimulated lots of ideas, talk and fun.
