Some variants you could consider...
An easier game
Do you want an easier game? Make one of the following adjustments: - Put the wolf 2 spaces backward at the start - Sort the tiles per color (or per animal) and put them next to each other (for very young children)
A more difficult game
Do you want a more difficult game? Make one of the following adjustments: - Put to wolf 2 spaces forward at the start - If you roll the dice and you roll at least one joker, you have to put the wolf 2 spaces forward if you make a mistake - If you make a mistake and both the animal and the color were wrong, the wolf advances 2 spaces
A very difficult game
Do you want a very difficult game? Make on or both of the following adjustments: - If you roll a result with a joker and you can flip a tile you must do so. You can only guess when it isn't possible to flip a tile. - When you make a mistake put the wolf one space forward AND the farmer one space backward.
