An indoor game of darts has also been developed, steel-tip darts generally weigh 18−26 grams and maximum of 50 grams is allowed in Amateur or Professional competitions such as the World Series of Darts. The common length of a dart is generally 15 to 20 cm (6 to 8 in) long, but rules allow for up to 30 cm (12 in). They are designed to penetrate dart boards made of bundled fibers (usually sisal).
