カメレオンの定義 (Definition of a Chameleon)

カメレオンの定義 (Kamereon no teigi) Definition of a Chameleon is a free PnP game from Japan.

It was a dark and stormy night. We had gathered at the pub in South End Station and held a welcome party for Harris, my best friend. Olivia, who up until now was only into drinking her scotch, called out, "Hey everyone, how about playing a card game?".

I wondered whether or not we'd be able to keep up with the ever changing rules of the game -- like a Chameleon.

At the beginning of the game, the way points are scored is undefined. But as the game goes on, you will gradually find out how to score points through the cards you play. Because of this, each game will play out differently.
