Touhou nimensou ～　reversible Night (東方二面相 ～ reversible Night)

User summary
東方二面相 ～ reversible Night (Touhou nimensou ～　reversible Night) is a fan fiction / alternate universe card game based on the video game series Touhou Project produced by Team Shanghai Alice.

Each card has 3 suits and effects. A special characteristic of this game is that two cards can be combined into a single double-faced card.

Players should initially be given 2 cards of each of the 9 types for a total of 18 cards. Each player should then proceed to freely combine two differing type cards, back-to-back, to create a total of 9 double-faced cards.

Every card has three suits (Power, Speed, or Brain). The suit that wins or loses the current trick is decided at the exact moment the first player or the winner of the previous trick plays a card. Once the suit has been decided, the card of that suit with the highest value wins the trick.

If there is a tie, all cards with the same highest value are flipped face down and the next highest value is calculated again from the remaining cards in play for the trick. If all players have the same value and the tie cannot be broken, no player is declared as winner for that trick.

The winner of the trick claims the points that were decided at the beginning of the game for each trick. All players, excluding the winner of the trick, may choose to turn over one card in their hand (which gives them a better chance to strategize in secret against their opponents).

Repeat for a total of 9 tricks. At the end, the person with the greatest amount of points is the winner.

A second edition 輝針城編 (Kishinjou edition) was released in 2016, with a new set of cards. Both sets can be mixed together.
