In 1992 the first tournament of the WDC (now PDC) was played and was named the Lada UK Masters. This event featured a bizarre rule named “equal darts” which meant you could tie a leg and force a replay or you could even win a leg after your opponent hit the double.
If player A went out in 14 darts and player B had only thrown 12 darts he still had the chance to win in 13 darts or tie a leg in 14 darts. If they both finished in 14 darts nobody won the leg and they would start again at 501.
