I’ve had several people ask about a craps procedure known as the ‘off and on’. I am going to discuss the ‘off and on’.
If you watch the video above, you will see that at 2:45, the shooter rolls a 9. RoadGambler has a come bet which then moves up (‘travels’, in craps parlance) to the 9.
If you are unfamiliar with the come bet, here is a detailed post on the come bet: https://roadgambler.com/craps/craps-come-bet/
RoadGambler’s come bet on the 9 remains on the 9 until the 8:43 mark when the shooter rolls a 9. At this point, the dealer pays the 9 a total of $155: $5 for the come bet, and $150 for the odds on the 9.
Normally, the dealer takes the come bet down, along with the odds, and returns the original bet (along with the winnings) to RoadGambler.
However, notice in the video at 8:46-9:15 or so, you see the red chip at the bottom of the screen. That is another come bet by RoadGambler.
That come bet, which was bet before the winning 9 rolled, then causes the winning come bet 9 to be subject to the ‘off and on’.
To understand why dealers and players exercise the ‘off and on’, let’s do an exercise where ‘off and on’ does not exist. Here is what happens…
Imagine that after RoadGambler wins the 9 come bet and odds at 8:43. The dealer then hands the original bet and the winning bet back to RoadGambler; all of it. The reason why the dealer hands all of the original bet money back is because the bet won. The come bet and odds are now OFF (meaning that it cannot win or lose).
Then what happens next is that the dealer would take the come bet and travel it to the 9. The come bet at this point is a contract bet. It must travel to the 9, where the house has the advantage to win the come bet. The dealer would then ask RoadGambler, ‘how much odds you want?’ RoadGambler would probably answer, ‘$100’. Roadgambler then tosses in $100 to the dealer. So the $5+$100 odds in now ON (meaning it is live and can win or lose).
So now RoadGambler has the exact same bet as before as if the dealer just let the come bet and odds up.
So to not waste time and hands chips back and forth, the player and casino just leave everything up, using a procedure known as ‘off and on’.
That’s the reason why the dealer didn’t take down the come bet and odds on the 9 when the 9 rolled.
