So i am interested in the hop bets for the 7 in craps. My question is what are the oods that two 7s will be thrown in a row on the come out roll within 30 come out rolls? When I play craps at the casino it seems like there are always alot of 7s thrown on the come out roll and I want to know if this is just short time occurrence or is it actually that 7's are more likely to come in a row due to it being the number with the highest possible combinations.

The chances of exactly two sevens in a row is one in 36. Since the come out is still in effect if you roll an eleven, I guess that has to be factored in but I am unfamiliar with these hop bets.

As s2dbaker mentioned, the chances of two consecutive 7s appearing are 1/36.

(1/6 * 1/6)

If I understand your question, (and obviously I THINK I do) I calculate there's a 50.9% chance that two (or more) consecutive 7s will appear on the come out roll, if given a chance to do so over a span of exactly 30 come out rolls.

And yes, two (or more) consecutive 7s are indeed more likely to appear in a row than any other number, for the very reason you mention... because it's easier to obtain.

For example, the chances that two (or more) consecutive 11s appear on the come out roll, in a span of exactly 30 come out rolls, is only about 8.3%

There are three hop bets you can make on the 7:
1-6
2-5
3-4

If the table you're playing at pays 15 to 1 on these hop bets, you are better off making all three of these hop bets than making a single bet on Any 7. (\$1.00 on each hop bet, for a total \$3.00 bet, will pay \$13.00. \$3.00 bet on Any 7 will only pay \$12.00.)

If the table pays 14 to 1 on the hop bets, it doesn't matter whether you bet the hops or the Any 7.

Ed, I'm getting 51.2% using WinCraps simulations (3 million come out rolls). Pretty close to your 50.9%, and I'll defer to actual math.

Anyway, Tom, I'm not sure that any of this can help you. Betting on the 7 with the intention of parlaying it when it hits doesn't change the house edge. And if instead your intent is to wait for a 7 to roll and then bet on the 7, the chances of it appearing on the next roll are 1 in 6, just like every other roll.

Forget the math.

Do you want to guarantee that two sevens will show up back to back,

Place \$200 in the hardways working on the comeout and I guarantee that you will roll sevens back to back......

So you figured out my idea. I am banking on the idea that two 7s will come up in a row on the come out roll. You bet all three hop 7s on come out roll and then parlay it up hoping that another 7 hits. If it does, then the payout is much more. I would think this would deminsh the house edge because you are not treating it as a single roll but a combined roll along with 13 bets of the casinos money. Also if it is over 50% for 30 rolls then what if we push it out to 60 come out rolls? Are we at 99% chance of hitting? The profit increase is so much that it would be easy to have a betting system to show profit over 60 come out rolls.

Those "13 bets" are not the casino's money. They're your money. When you parlay, it's your money that you've chosen to leave on the table. And just because you've chosen to increase your bet, that doesn't change the house edge.

Also, increasing the number of come out rolls in our discussion won't change anything. Yes, the chances of hitting two 7s in a row increases, but so do the number of losing wagers.

I'm not trying to discourage you from making the bet. A parlay is very exciting when it hits. However, be aware that you will not see a profit in the long run. It will eat away at your bankroll pretty significantly with its huge house edge. (This particular parlay has a house edge over 20%.)

The best parlay for a non-free bet is to start with a \$25 four or \$25 ten and press it all the way until the money seems ridiculous.

The combined edge doesn't EVER get anywhere near a hardway's first hit edge, and you get 9x return after only two hits.

+1 on the 4/10 buy... and I'll add twice as nice when the commission is on a winning bet only!
Some people need to reimagine their thinking.
