As the German proverb says, buying "a cat in a bag" is buying something of which you don't really know the value. Filou is a bidding game based on this principle: each round, players bid on lots whose true value they do not know, at least partially,...
Each player receives the same set of 10 cards of his color including 7 cats (of negative or positive value, between -8 and 15), a small dog card, a big dog card, and a rabbit card. He also receives 15 mice in tokens. One of the cards in each set is discarded by the player's neighbour to the left. Finally, a number of mouse cards (green) are placed in the center of the table depending on the number of players, in increasing order of their value. Each mouse card receives the number of mouse tokens corresponding to the value of the card.
At the beginning of each auction phase, each player from the first player places one of his cards face down under the first available mouse card. These cards are the contents of the bag being auctioned for this round. The first player turns the first card in the row over (the one under the chat card in the bag). Each player, in his turn of play, then has the choice:
-Either he bids (with his mouse tokens) on the proposed lot.
-Either he passes, turns over the first mouse map still secret, and recovers his bet mice and all the mice placed on the smaller mouse map.
When all players have passed except one, this player pays his bet to the bank and recovers the entire lot, as well as the first player's marker. If there is a small (resp: large) dog in the batch, it cancels the animal with the lowest (resp: largest) value in the batch; if there are two or more dogs in the batch, they cancel each other out. A rabbit card counts as zero points.
Yeah, okay, but how do I win?
After the ninth and final round of play, each player adds up the value of the cat cards he or she has won with his or her remaining mouse chips. The player with the most points is declared the big winner!
