The Labyrinth of Cards

User summary: In the game カードの迷宮 (The Labyrinth of Cards), players explore a six-floor deep labyrinth. In each floor, there is treasure whose value is hidden until someone explores that floor. You collect that treasure if you commit most effort to exploring that floor.

The game is played like blind auction, but six floors are auctioned simultaneously. You may play an exploration card, which indicates how much effort you commit, face-down on your current floor or on a deeper floor, but once you explore a deeper floor, you may not go back to an upper floor.

At the end of the round, count up the treasure values players have collected. The player with higher total wins the round. You have to win two rounds to win the game.

With four players, the game is team battle (2 players vs. 2 players).
