If you enjoy throwing darts with friends at your local hangout, organize a darts tournament so you and your fellow enthusiasts can compete against each other in teams. It can be a friendly contest, or you can award prizes to the winners. Here are a few ideas to get you started.
Collect names and any entry fees from participants. You can have as many players as you like. However, darts is more fun as a team event so you will might pair the participants. You can do this through some random method, or let players sign up in pairs. Start taking names early and promote the event so you have plenty of people to play and watch.
Organize your tournament bracket (see Resources below) for the number of teams playing. It is best to place team names in a hat and pull them out randomly to decide who will compete against whom first.
Begin the tournament by having the first two randomly-chosen teams on the bracket flip a coin. The winning team can choose to diddle either first or second, starting the game of 501. The person who loses the coin toss will decide whether to diddle first or second to begin the second game of Cricket. If one team wins both 501 and Cricket the match is over. If the match is tied, the coin is tossed again. The winner decides whether to play 501 or Cricket for the third and final round.
Extend the bracket as you go, pairing up teams until the last two teams compete in the final match. Depending on the number of teams competing, you may choose to make your darts tournament a multiple-day event, having a darts final on the last day.
Decide what prizes to offer winners. If you are taking entry fees, you can divide the pot so that the winning team gets half the pot; the second place team receives half of what's left, then the third team gets half of the balance and so forth. So if there's $400 in the pot, the winners get $200, the second place finisher gets $100, the third place team takes home $50 and so on.
Up the ante by offering other ways to win money. You can allow participants to pay a dollar to enter other events, creating extra optional pots. Create a "high out" pot for the person throwing the highest score of the darts tournament. Pull a random number from a hat for a "guaranteed mystery out," offering the pot to the first person to throw that number. You can organize as many of these side events as you wish to keep the games interesting.
