The Sakabashira Game is about a 21-year-old man who has lost his memory and wakes up in a strange place with six people.
The group works together to look for a way out even though no one knows how they got there or why. The title of the game, which refers to a Japanese theory about wooden buildings, shows that the game is based on Japanese culture. In particular, it means to turn a tree on its side during construction so that it can be used as a stake in a wooden building.
Have fun and good luck!
