domino

A domino is a small rectangular block used in the game dominoes. Each block has anywhere from 0 to 6 dots.

A domino is a small, black rectangular game piece with white dots. In the game called dominoes, sides of the dominoes with equal numbers are matched. Dominoes are also stood up to create elaborate patterns that look pretty impressive when they’re knocked down. If you set them up right, knocking down the first domino will knock down hundreds and even thousands of others. This use of dominoes inspired the domino effect, when one action inevitably causes others.
