The Werewolf Game: Lovers (2017)

Same type of game that is played in both adaptations.
Key points >
- gore
- blood
- murder
- mystery

In a mysterious setting, the death games involve players with hidden roles and objectives, requiring strategic interactions and deceit to achieve survival / victory, while mistrust and suspense build among participants in thrilling violent fun =)

Death Game. Outwit other people and Survive The Game. Be the Last One Standing. Series of Movies. Survive.

The main character also, joins a game what he has no idea about, to pay off his debt. Unlike Lovers, in Kaiji there are multiple games which involve death. So if you liked Lovers and need something else similar to that, I reccomend Kaiji.
