I knew there was an old thread on this somewhere.

I saw Double Ball Roulette on my trip to the Strip last Tuesday. Please check out my new page on the game (by clicking the link). As always, I welcome corrections, comments, and questions.

I haven't seen this game, so this may be a dumb question, but if "the game uses compressed air to shoot the two balls out of a tube almost simultaneously", wouldn't there be a greater likelihood of the balls settling in the numbers relative to where they were shot from? Because I haven't seen where the balls emerge from, I don't know if this is across from each other or at a 90 degrees but it seems it would decrease the chance of the two balls landing in the same number.

I think the physics question needs more study. I can't imagine that the probability of the 2nd ball landing in each spot is equal to 1/38. I'd like to get my hands on the study run by the "independent testing lab."

Actually, my patent for Poker For Roulette DOES cover that possibility.


In fact, my Math Page includes math for 3, 4 and 5 spins. The intro of that page says the following:
Quote:

The four spin version is better thought of as a four result version. It is intended for Roulette systems where two results are produced in a single spin, enabling resolutions in only two spins.

I was thinking about both this double ball system as well as TCS John Huxley's Double Action Roulette two wheel system.

When I played it the dealer said "You get two chances to win but the wins are half as much." I think the recreation player and non-math expert would incorrectly assume that the odds are the same as in single-ball roulette.

In other words, I think few players will know these bets have a house edge over 10%.

I had a long talk about this at the gaming show but I don't recall the explanation I was given. It may be the time between the two balls is randomized so that there isn't correlation between the results. However, I still have a hard time buying the probability of the second ball landing in the same slot as the first ball is 1/38. My gut says it would be slightly higher. However, it would need to be 1 in 31.6 for the Double Ball Jackpot bet to be positive, and I doubt it is that high. If it were, I'm sure it would have turned up in the many months of wheel testing.

Actually, it's exactly the same edge as if you would parlay an outside bet on a standard double zero game.


Wiz -

The first table is for the outside bets, but it has the heading "Inside Bets".

I think it might be prudent to include my comment about the parlay on a standard game.

And, along those lines, is the edge on the inside bets the same as placing the same bet on two successive spins of a standard game?

True, but they may notice how much faster they lose their money.

The edge is not the same. Let's look at parlaying a six-number bet twice. If you win, $1 would turn into $36. The probability of winning both times would be (6/38)^2. So, the expected return would be 36*(6/38)^2 - 1 = -10.249%.

In Double Ball Roulette, the six-number bet has an expected return of -7.756%

I'll waste $100 at this table when I visit this weekend, staying at the Excalibur and still need to take them up on their rebate.

$1 on the same number every time for sure.

This entire game is one BIG 6 / BIG 8 bet. You shouldn't be able to make the same bet (one dollar on two single numbers vs. 2 dollars on 2-way) and have different payouts.

I think you guys are missing the point on the HE comment.......players will not necessarily know the higher HE, but they will feel it! And when they do & the "novelty has worn off, they will go back to regular roulette where they mysteriously seem to get to play longer and not lose as much.

Yeah, that was my point exactly.

I remember being in the baccarat room at MGM (min $100/hand). One lady made a comment that of course she would lose, but her money lasts a long longer than at the slots. She may not know the edges but she can feel the difference. I think that this is common.

I would like to know if this double ball roulette has got better or worse conditions for a regular player.

Why does it change when youn play 4 numbers?

What is the house edge when you play strait bet and 2 numbers?

Kind regards

It seems that it adds 0.7% to regular 2.7%.
