Fun little logic puzzle! I did all 3, and the 18 card case was my fastest! I was a little confused about the rules at first because I read them on the page and not in the Help section (I didn't know what the red circled numbers meant). I also wasn't sure if the murderer always lied or not - when I solved the 12 card case it didn't lie.

Neat little mechanic--a great combination of two puzzle formats (the "organize the elements based on clues to their positions" puzzle and the "liars and truth tellers" puzzle). I've only played it on the easiest difficulty but I can definitely see myself coming back to try this at harder difficulties.

Really great fun! I was getting lost in the harder game modes with more cards, but I think that's just me lol would highly recommend to my friends.

I really like the mechanics. Good replayability, too.

I really liked. I love this kind of logic problems.
