Help me find a death game/horror manhwa/manga (?) although I'm pretty sure it is a manhwa since I remember the panels being colored, but it also might have been Japanese.

Hi, this might be a stupid post but there is this one (I'm pretty sure) manhwa that's been at the back of my mind for the longest time, but I just remember what the name was.

I think it was some sort of death game concept. I'm not sure, but losing a game/round would result in a death penalty. I remember one of the arcs of the story where the main character is in a game with a couple of more participants and they all play a game where there are 2 imposters (I think). The way to win this game is to either to get rid of the 2 imposters before they poison everyone at the table, or the 2 imposters poison everyone else before they get found out. The setting was a room with a table I believe; all the participants are strapped to the chairs so they cannot escape. The voting system for this game was for everyone to close their eyes and point at the person they wish to vote on who they think the imposter is. Same thing for the imposter, everyone has to close their eyes as the imposters get to keep their eyes open and point at the person they want to poison.

I know some things for sure, 1- it is not abyss cruise, 2- it is not "death's game" 3- I think I first picked this up after seeing a YouTube post summarizing the chapters/plot of this manhwa.

Also, this post is open for manhwa/manga recommendations for death game/horror/anything alike of this genre, it would be greatly appreciated! Thank you.
