Very creative idea. Building something as simple as rock paper and scissors into a complex game that will determine your destiny. We only think the game as pure luck but this movies proved that there is a logical way to win. The movie also exposed the nasty truth of humans. Well the protagonist is the only one that stayed true to himself. There are many mysteries in this movie that doesn’t have an explanation which I think really requires your detective skills to figure them out. And the last scene on the boat was very heart warming. This movie is an adaption of a Japanese story, not a copy.
