Since games have a minimum number of runs/goals (one) but no maximum, a very high scoring game - which would stop affecting the outcome of the game's individual total once the number is reached - would still be able to affect the Grand Salami. That's generally going to be the case, too. In fact, if you added up the six games above, you would've noticed that they summed up to 50.5, not the 51.5 listed. The Grand Salami is not necessarily the sum of all the totals on the slate. And for an 'under' bet to cash, the cumulative total would have to remain at 51 or below. In this case, for an 'over' bet on the Grand Salami to be graded as a win, 52 or more runs would have to be scored across the six games.
Here's an example of what that might look like on a 6-game MLB slate - the grand salami will be 51.5, so you can bet on whether or not there will be more or fewer than 51.5 runs scored throughout the day. In other words, you're betting on the total number of runs (or goals) that will be scored over the course of every game that day. The Grand Salami betting option is a cumulative over/under bet for all the games on a given baseball or hockey slate.
