Round Robins
Round Robins are a way you can explode your winnings if you are hot. Win less than 50% and they can gut you. The Round Robin is every available parlay base on the game totaland the leg selections. Below is an Excel spreadsheet to calculate number of bets in a round robin.
If you do an 8 game 4 and 5 leg your total bets would 70 plus 56, or 126. If your bet is 12 games 3 legs and you lost two games your number of winning bets is 120 (look at 10 game 3 leg).each bet pays 6 to 1 plus your money back or 6x120+120 = 840 minus the 220-120 lost, 200 gives a return of 840-200 = 640 for the 220 wager. Or a 440 profit on a 220 wager.
On a 3 leg with 10 games you need to win 6 games to have a payout higher than single bet wagering, see below 20x6 plus 20 = 140 return on your 120 wager. Single straight bets with 60% win returns a 14.5% profit. 3 leg parlays with a 60% win returns a 16.6% profit.
Parlays
Parlays are a wager to win every single bet in a series. A 3 leg parlay means you must win all three games or you lose the wager. The payoffs grow tremendously base on the number of games. If you push on one game the parlay payout drops to the next level. For example if you wager a 3 leg parlay win 2 and push on 1 the payout is the same as for a 2 leg parlay.
Just because the mathematics says you should win X number of dollars does not mean you will. Most sportbooks round down on all but the 3 leg parlay. One exception is CG Technology. Those sport books consist of Hard Rock Cafe, Tropicana, The Venetian, and other. Often a way to bump your payment to the formula at other books is to add a moneyline wager to the collection. Try it with a small bet for verification. Often you can get a higher payout by adding a small positive money line.
With the expansion of legalize sports wagering I've been using West Virginia's Charlestown Casino. There they actually round up on the 3, 8, 9, and 10 legs parlays. See below for the payouts.
