Crows are smart, but they have a weakness for shiny objects. You have a shiny object. The problem is, so do your friends. There are too many shiny objects and too few crows!
Players take turns placing tiles and then positioning their shiny objects to attract the most crows. Crows flock to the shiny objects based on simple rules. It’s going to take some wits if you’re going to attract the most birds! When all tiles have been placed, the player who has attracted the most crows wins.
