ClaytonCon returns for another fabulous day of tabletop gaming.
ClaytonCon is Mississippi Mills' largest board game convention. Every year, dozens of people descend on Clayton, the picturesque hamlet located in the heart of Mississippi Mills, for a day of board and tabletop games.
ClaytonCon supports an inclusive gaming culture. We do not tolerate harassment based on race, ethnicity, gender, gender identity or expression, appearance, body size, sexual orientation, disability, religion, or age. We expect everyone to play nice.
Play Wingspan to be automatically entered into a draw. The Clayton house rule of an extra point per duck in your tableau will be in effect.
Got a prototype you want to try out? Set up in the main hall and play with enthusiastic gamers. Contact us for details.
