28 High-quality wooden pieces with bright patterns. Each domino is 3:6:1 cm, wooden and polished. The game develops critical and calculative thinking of the players. It improves coordination, problem-solving skills, attention, concentration, enhances multi-tasking, brain's speed and social skills. Start with 6 dominoes for each player. Each player must in turn then play a tile onto the table positioning it so that it touches either end of domino chain which thus gradually increases in length. If a player can lay a domino, then it must be played. Otherwise, the played knocks or raps the table and play passes to the next player. Normally play stops when one player chips out (plays his last domino).
