Liar game has more puzzling elements and is a smarter show compared to squid game. The jdrama is an adaptation of the original manga so it is darker than the korean version (which is quite different from the manga). If possible, go and read the Liar Game Manga instead of watching both the adaptations because- the acting in the jdrama is not the best and the kdrama is not as thrilling as the original story in the manga.

As the gods will is crazy. It has that weird element japanese stories have. You'll enjoy this if you liked squid game.

Both are amazing thriller survival asian dramas full of games and violence. If you thought squid game was pretty good then get ready for Alice in Borderland.
