Dominoes is a tile-based game played with rectangular "domino" tiles.

The official world record for the most people playing dominoes simultaneously belongs to the Dominican Republic. On January 22, 2012, a staggering 3,344 dominophiles gathered in Santo Domingo in an event organised by Luis Alberto Ramirez Feliz in Santo Domingo, Distrito Nacional, Dominican Republic.

The falling dominoes scene in the 2005 dystopian political thriller film V for Vendetta involved 22,000 dominoes assembled by four professional domino assemblers for the two day shoot.

Dominomus was a female house sparrow that flew into a convention center in Netherlands on  November 14, 2005. She caused 23,000 of the dominos being prepared for “Domino Day 2005” four days later to be knocked over. A hunting company hired to capture the bird with nets and sticks failed, and finally just shot it, sparking an animal rights controversy.

Any domino can be used to knock over something 1.5 times its size. So you can build up from small things to knock over pretty much anything if you have the time. If you started with a domino the size of a carbon atom, you could knock over the Burj Khalifa with a 1.22 kilometer tall domino in just 74 steps.

The reason why any domino can knock over another object up to 1.5 times its size is due to gravitational potential energy.

The dots on dominoes are called 'pips'.
