Snood is a puzzle video game created in 1996 by David M. Dobson.Today, versions exist for a variety of platforms, including Windows, Mac OS, Palm OS, and other systems, including unofficially on the TI-83 and TI-84 calculators.Similar to other puzzle games such as Puzzle Bobble, Snood has simple rules. Connecting three or more identical Snoods makes them disappear from the board. When the board is cleared, the level advances. If the Snoods reach the bottom of the screen, a life is lost.
