Opis w języku angielskim:
Each player randomly draws a family of monsters which will become their family for the duration of the game.
In turn, each player will be able to place a monster card on the playing area, covering it as desired: one half card, two half cards or one whole card. The goal is to succeed in expanding your family of monsters on the playing area, without the other players guessing your identity. Knowing that each monster placed surrounded by the 4 ribs is protected and can no longer be covered (except Black Monster card).
As the cards are placed, players will also be able to cover some of them including the famous energy drink "Monster Bull" which will earn 1 more point at the end of the game. Once each player has placed all their cards, the Black Monster appears. Scaring away other monsters, the Black Monster card can be placed on any whole card already placed. Once the Black Monsters have been placed, the cards placed underneath are removed from the game and new monsters reappear. It's time to count the points! Each monster in your family and each drink token in your possession earns you 1 point. The player with the most points wins the game.
