Each player has 15 Top Hats in their colour, pass some to your opponents and make 5 stacks of 3 hats each in secret, with one of your hats on top of each stack to show ownership. Place them and then move one space or jump your own hat stacks around a hex board, capturing opponents' pieces like Checkers/Dame. With each capture, remove the top Top Hat in the stacks you jumped, leaving them by the board, thus changing ownership of the stacks. When all the remaining stacks left on the board are owned by you, you win! - BoardGameGeek
