Google is celebrating the Lunar New Year, marking the start of the Year of the Snake with a new Google Doodle game. Here's how to play.

The festival is celebrated by several ethnic communities across the world, where it is known as Chunjie (Chinese), Seollal (Korean) and Tet (Vietnamese), among other names. In English, it is commonly referred to as Lunar New Year, after the lunisolar calendar that many of these communities traditionally follow.

Many Chinese who work in bigger cities return home during the eight-day national holiday in what is described as the world's biggest annual movement of humanity.
