The goal of the game is to try to set up a chain of domino-like pieces (starting with one of your own kings) that will topple one of the adversary's king pieces when tipped over. Each turn, you take two actions. The actions can be place a piece, turn a piece, move a piece (once all your pieces have been played), or topple a chain. If you knock down the opponent's king, it is out of the game. If you don't, you lose your king instead. Through your movement or rotation of pieces, you can interfere with your opponent's chain as well as build your own. - BoardGameGeek
