The Game's Name is Kidnapping

A traditional mystery novel that maximizes sophisticated narrative tricks and twists.
A kidnapping plot conspired by the hostage and the culprit is set as an unconventional premise, and this entire process is reconstructed into the frame of a game.

This seems to represent the cold worldview of judging all modern human relationships and values by win or loss.

In fact, success in the work means winning the game, and an arrogant elite who prides himself on having won every game so far based on his outstanding intellectual ability appears.
But even he is merely a useful pawn in this big game.

There are many foreshadowing clues throughout the work suggesting that the essence of this game lies elsewhere.

A hidden card appears at the last moment, and the work ends with an open conclusion. Is it a draw?
It heralds that another dimension of the game has begun.
