Teceangl's rules are excellent. The game is also sometimes known as the Round Dozen.
Most versions display the numbers up to nine but they can also be through twelve.
I think the larger spread plays better. It does not need special equipment and can be played by drawing the numbers on a sheet of paper. Games of the World edited by Frederic Grunfeld shows a very interesting and intricately carved box from Africa that uses sliding panels to keep track of the numbers covered.
