The rules of the game

 All aspects of the game are assembled on play cards. The cards are shuffled and equally distributed among the participants (5 to 8 per group)
During the game, in turn, every player can put a card on the game board, at every step of the game. Each player can decide not to put a card on the board game if no suitable card is available. The turn then goes to the next player.
Before putting a card on the board, the choice for that particular card is discussed briefly with the other players but it is the player having the card in his deck who can make the final decision.
If a player does not have a card for that stage of of the game, or decides not to put his card, the player next to him takes the turn.
The game animator supervises the whole process, asks questions and gives suggestions.
