  • I loved it because it’s not the typical book you just read and move on from. It gets you thinking, jotting down suspects, and wanting to solve the whole thing. The set is definitely worth it.

    🇬🇧 Charles R.

  • I bought it out of curiosity and ended up totally hooked. The Alice one is amazing, but the Murdoku one is great for doing something different instead of just being on your phone.

  • I received it instantly and was able to open it on my phone without any issues. I like that they are mystery, logic, and murder-themed games—perfect for passing the time while giving your brain a workout.
