Begin by drawing 7 domino tiles each for a 2-player game. Set the first tile on the board to start the domino chain. Switch with your partner to place a tile to either end of the chain, connecting the numbers. Score points by forming multiples of 5 with the addition of the numbers on the tips of the chain. Utilize strategic tiles like doubles to boost your scoring opportunities. Block your opponent by reducing their options. The game finishes when a player exhausts their supply of tiles or no more plays are possible. The player with the highest score claims victory.
