Tell a story so that the last person to guess will guess it right.
In Windmill: Cozy Stories, players are storytellers who weave short tales based on the hidden picture cards they draw. While one player tells a story, the other players attempt to guess the visible card that matches the story.
The more opponents who guess incorrectly, the more points the storyteller receives when someone finally does correctly identify the card. On the other hand, if all players fail to guess the picture, the storyteller loses points instead of winning them!
You score points both by telling stories that are identified correctly and by guessing the stories told by others. Whoever earns the most points over the course of the game wins.
