About 妖怪ふわふわ (Yokai Fuwafuwa), from BoardGameGeek:
A mysterious yokai has taken possession of your mind, leaving your thoughts fuzzy, fluffy, and hopelessly unclear. You can barely remember how to play a trick-taking game, let alone predict how many tricks you might win. But as the confusion gradually fades, your thoughts become clearer. Can you recover your wits before the yokai's mischief costs you the game?
Yokai Fuwafuwa is a trick-taking game with a dynamic bidding system. Players begin each round with an uncertain bid, represented by cubes covering numbers on their Bid Cards. Instead of playing a card normally, a player may spend a cube to play a card face down as Fuwafuwa, declaring whether it will win or lose the trick. Its strength is determined by the player's current bid values and the other cards played. As the available bid values narrow, players gradually reach a Clear Mind state, preventing further Fuwafuwa plays. Points are awarded for unused cubes, accurately predicted trick totals, and successful predictions made after achieving Clear Mind.
