A football double involves the purchase of tickets that have links to hidden random numbers. The winner is determined by the ticket holder’s
numbers corresponding with the football jersey numbers of the scorers of the first two try (Rugby League and Union) or goal (football / soccer) scorers in a particular football match from each team. The respective combinations are 121 (football / soccer), 169 or 289 [including reserves] (Rugby League) and 225 (Rugby Union). It can also be applied to basketball where the total number of registered players per team is known. The minimum number of players registered in the Australian NBL is 12 so 144 tickets per game.
Customers purchase a ticket or tickets that are each numbered 1 to 289 respectively. When the purchase is completed they can download their doubles numbers in a PDF file for each ticket. The links to the doubles numbers are randomly sorted for each game then uploaded to update the links to the doubles numbers for each ticket. The random sort is dome using functions in Excel or Google Sheets.
You can offer doubles in more than one game at once by including the name of the teams in the ticket name as well as the ticket numbers. The links will be randomly sorted prior to uploading but they are still linked to the same set of PDF files of doubles numbers.
Doubles Rules (Eg Rugby League)
1. Doubles will be paid out on FIRST POINT SCORERS – if a team does not score, the double will be paid out on the HOOKER position generally – number 9. The first number of the Doubles is the home team. When there is not a home team as in a final then a team will be nominated and published in the rules of the game and above the selection of tickets.
2. Doubles will be paid out on :-
• the jersey number the player is wearing when he scores the points, if numbered one (1) to thirteen (13) or;
• in the case of an interchange situation, the number of the player that replaced a team member numbered one (1) to thirteen (13) as part of the interchange process if numbers 14 to 17 are not being used; or
• in the case of a pre-game replacement situation, the number of the person that person replaced
WHEN HE OR SHE SCORES THE POINTS.
It must be noted that the player scoring the points will be identified by the jersey number he is wearing, if numbered one (1) to thirteen (13) or seventeen (17) in the case of reserves.
3. If a player wearing a number above 13 is the first points scorer his ‘interchange/replacement’ number will be clarified by the respective team manager from each of the NRL teams. Team Managers validation will be final and no discussion will be entered into in respect to their decision. (Where numbers greater than 13 are used and not as interchange then the numbers are allocated in ascending order against the missing numbers in the range 1 to 13.)
4. Winners will be notified by email and the winning combination will be published on the website. You have the option of also notifying all participants of the results.
5. The prize pool is 60% of the total revenue from tickets sold. If the winning ticket has not been sold the prize pool is distributed to the nearest combination to the scoring double. The nearest combination is calculated on the total of the absolute difference between the scoring double and the next available ticket. Eg Team 1 -2 difference and Team 2 +3 difference the total absolute difference will be 5. Where there is more than one ticket with the same difference the prize pool will be divided equally amongst those tickets.
Fund Raising
Taking a Rugby League game as an example – 169 tickets at $5 per ticket = $845. Assume the prize pool is 60% ($507) leaving 40% ($338) for your organisation from that particular game.
