Longest domino line

A domino row is a series of domino tiles that are placed in a line one after the other, so that when one tile is pushed, it knocks down the next one, and so on until all the tiles in the row have fallen.

Domino rows are often used as a hobby and a form of entertainment. They have also been used in events and competitions, where giant domino rows are created that can knock down thousands of tiles in a single chain of events. Creating domino rows requires skill and patience, as it is important to ensure that all the tiles are aligned and fall in the correct order.
