If you want to close the post feel free. I just found the info I was looking for. But one question is: Are they profitable?
Here is the info I found:
Round Robins
Typically for football and basketball the Round Robin option allows you to select up to 8 teams and produce a series of parlay bets involving a nominated number of teams in every combination. To select this option click the 'Round Robin' check box. You will need to also select the number of teams in each parlay. The drop down menu labeled 'Round Robin teams in each parlay' to the right of the 'Round Robin' check box provides this ability. You need to select one of the following:
3 teams every 2 ways = 3 bets
4 teams every 2 ways = 6 bets
5 teams every 2 ways = 10 bets
6 teams every 2 ways = 15 bets
7 teams every 2 ways = 21 bets
8 teams every 2 ways = 28 bets
4 teams every 3 ways = 4 bets
5 teams every 3 ways = 10 bets
6 teams every 3 ways = 20 bets
7 teams every 3 ways = 35 bets
8 teams every 3 ways = 56 bets
5 teams every 4 ways = 5 bets
6 teams every 4 ways = 15 bets
7 teams every 4 ways = 35 bets
8 teams every 4 ways = 70 bets
6 teams every 5 ways = 6 bets
7 teams every 5 ways = 21 bets
8 teams every 5 ways = 56 bets
7 teams every 6 ways = 7 bets
8 teams every 6 ways = 28 bets
The selected item will indicate to you the number of teams you need to select as well as the number of bets that will be generated. The number of teams you select in the drop down menu must match the number of team selections you check on the betting page, if this does not match then an error message will be produced. The total number of bets will be multiplied by the stake $value you select. This amount will be deducted from your account when the bets are confirmed. Eg. if you select 6 teams every 4 ways this will generate 15 four team parlay bets. If the stake value selected was $10 then 15 x $10 = $150 would be deducted from your account.
