Can anyone answer these questions for me please?
What are the odds that a dozen will hit?
What odds does the casino offer for a dozen?
If a dozen hasn't hit in 3 spins what are the odds it will hit on the 4th spin?
What odds does the casino offer for hitting a dozen on this 4th spin?
On an American wheel, with 0 and 00, the odds are 31.58%. Excluding the 0's, there's 36 numbers, so each number has a 1/36 chance. A group of a dozen is exactly 1/3 of the board, so your chance of hitting a number in a dozen is 33.33%. Adding one or two zeros in the game then changes the game from even to a house edge, hence the lower than 33.33% on any dozen. Although you can play the house's zero(s) in a few combinations, dozens are not one of them. Any zero will immediately cause any dozen wager to lose.
In this game, however, it's not quite that simple, since has been repeated numerous times, no matter how many times an event has happened or not happened, the next spin does not carry this information forward. A roulette Tote Board was an ingenious idea to trick people into playing on past performances. This fallacy lines the house's pockets more than any other 'suggested' number or sequence selection.
If you're asking payout, Dozens pay 2:1, plus the return of your wager. You put $5 down, and if you win, you are given back $15 for a $10 profit.
If a dozen has not hit in 4 spins, or 400 spins, it still has the same 31.58% chance on the next spin.
The payouts do not change depending on how many times a certain sequence has not hit.
Hope those answer some questions...
As to wagering, there's many strategies, but the most popular is a progression based on intended profit. This depends on odds. For outside bets that pay 1:1, you typically will double your bet each time. Here's an example. You place $5 on red, and lose. You expected to profit exactly $5, but you're $5 down now. You bet $10 on the next spin, and lose again. If you had won, you would have made $10, but you were 5 down, so your actual profit would still have been $5, or .5:1. Now you bet $20, and lose again (not at all unrealistic). If you had won, you would have collected $20 profit, but after factoring in the original $5 loss, and then the $10 loss, you still only truly made $5 profit, or .25:1.
As this gets worse, you can realistically be wagering $320 on red (after 6 successive losses, which is STILL very realistic), and if you won, you would have only made $5 total profit. This is a VERY dangerous undertaking, and the risk to reward plummets with each loss and the next wager.
To counter the possibility that the gambler has unlimited funds to keep doubling, all roulette tables have MAXIMUM limits, both for any individual wager, and all wagers combined. Table maximums for physical tables in Vegas are quite generous, but most online software tables have a limit somewhere around 300-500. Once you've hit the limit, you're really done. On a $500 limit evens table, that 320 wager would be your last double up attempt, because your next wager would be $640 (to win $5). If you lost that $320 wager, your total losses for that sequence would be 5 + 10 + 20 + 40 + 80 + 160 + 320, or $635, all gone after 7 losses.
As we move up the odds chart, you don't have to double EACH spin to stay in. For dozens, which pay 2:1 to begin with, you would wager $5. If you won that wager, you'd profit $10. If you lost, you can now wager $10, which is a double. A win would profit $20, minus your last bet, and your profit would be $15, which is better than if you won the first wager. If you lost, we'd move to $15, not a double of $10. You profit would be $30, minus the 5 and 10, for again, a $15 profit. If lost, we move to $20, not a double. Profit would be $40 minus 5, 10 and 15, which would end up back to $10 profit.
You can use a spreadsheet to figure out all of these profit/risk scenarios for the various odds on different wagers. The bottom line remains, as you continue to lose, 2 things happen. You start tickling the table maximum, and you gain very little for such huge risks. This is why people who use ANY type of system are welcome with open arms to any roulette table.
Hope that helps.. and this post was just general in nature, and has NOTHING to do with this Zone crap. I'll let him explain that.
