Using the Martingale Betting System to win

Genie · January 25, 2024 ·

A genie educating about using the martingale betting system in roulette.

The martingale betting system is a commonly used betting system, which like Roulette has its origins in France. The betting strategy is generally used for stakes where there is an equal (or almost equal) chance of one of two outcomes occurring. The most basic example is a coin toss but the strategy is commonly applied to Roulette.

The strategy is based on the bettor doubling their bet after each loss to ensure that their first win recovers any previous losses along with an additional profit. Be warned however that the martingale strategy is not fool proof as (1) it presumes the gambler has infinite wealth (2) betting limits exist.

Application of the Martingale Betting System in Roulette

When applying the martingale betting system to Roulette it is important to remember that the strategy is applied to situations where there is an equal or almost equal chance of one of two outcomes occurring. In Roulette this means betting on outside bets, i.e. red or black or odd or even where the payout is 1:1, and doubling the bet so as to recover losses when the player’s selection is not drawn.

Due to the possibility of drawing a zero it is important to note that the chance of drawing either outcome is not 50%/50% but rather, 47.4%. This doesn’t affect the strategy however as if you do not draw your selected number you still double your bet. It is best to display this via an example where the martingale strategy is applied to the selection of red or black in Roulette.

A player decides to bet on the outside bet of “Black” in Roulette and places a bet of €1 on this outcome.
If the result is Black, that is fine and the player will be paid at 1:1
If the result is not Black, i.e. Red or zero, the player loses their stake and places a bet on Black again, this time for double their previous stake, €2 in this instance. If the result is Black this time, then the return to the player is €4 which will cover the loss they made in their first bet as well as meaning the player pockets an additional profit of 1X their initial stake. If you win begin the process again with your original stake.
Betting continues in that doubling manner when a player doesn’t win, e.g.

Selection	Stake	Result	Total Profit/Loss
Black	€ 1	Loss	– € 1
Black	€ 2	Loss	– € 3
Black	€ 4	Loss	– € 7
Black	€ 8	Loss	– € 15
Black	€ 16	Win	+ € 1

System Limitations

As mentioned previously, while this casino betting system may lead to short term gains, it is not fool proof. A players bankroll may not be sufficient and they could run out of money while on a losing run.

In addition, most casino tables have a maximum bet of €500. This means that punters can double their bets by up to a maximum of 9 consecutive times on a stake of €1 before they would then breach the table limit for outside bets. Statistically, this means that in Standard or European Roulette there is only a 0.24% chance that there will not be a winning outcome in 9 spins. In American roulette, where there are 38 potential outcomes this is slightly greater at 0.31%.

Best Price Guarantee Bookmakers – don’t miss the opportunity to lock in higher returns

How do Best Price Guarantees work?

When a bookmaker offers Best Price Guaranteed (or BPG) on any event or market this guarantees all board and early prices against the starting price (SP). Essentially, Best Price Guaranteed, or Best Odds Guaranteed (BOG) as it is sometimes called is best explained by an example.

Best Price Guaranteed Example

You spot a horse is available at 12/1 on the morning of a race and proceed to take place a bet of €10 with a bookmaker offering BPG.
At the off your horse has drifted to 14/1
Your horse wins and because you bet with a Best Price Guaranteed bookie you are guaranteed the best price. This means that you don’t miss out on €20.
In the long run this could add up to a lot so it is a good idea to bet with Best price guaranteed bookmakers

It is estimated that offering best price guaranteed costs bookies approximately 2.5% of turnover and as such offers excellent value for punters.

If you are a keen horse or dog racing punter, then it should be a prerequisite to bet with a best price guaranteed bookmaker.

Sounds good, but what are the caveats with best odd guarantees?

As with every promotion or offer that bookies run, there are terms and conditions. The most common are below.

Best Odds Guaranteed (BOG) is a popular promotion offered by bookmakers, primarily for horse and greyhound racing. However, the offer typically comes with a set of terms and conditions that bettors need to be aware of. The most common terms and conditions associated with BOG include:

1. Race Day Only:

BPG is typically only available for bets placed on the day of the race, and sometimes only after a specific time (e.g., 8 AM or 9 AM). Some bookmakers may extend BOG to bets placed the preceding evening however.

2. Eligible Markets Only:

Best Price Guarantees usually apply to horse and greyhound racing only.
Bets on international races may not be included unless it is otherwise explicitly stated. Typically, BPG is available only for UK and Irish races, though some bookies do extend it to selected international races.

3. BPG Bet Restrictions:

Multis/Parlays/Accas/Accumulators and system bets: Some bookmakers exclude multiple bets (e.g., accumulators or Lucky 15s) from BPG.
Free Bets: Winnings from free bets are often excluded from the BPG offer.
Cashed-Out Bets: Bets where punters cash out early may not qualify for BPG.

4. Payout Limits:

Bookies often impose a maximum payout limit for BPG winnings. The max payout amount varies by bookmaker.

5. Excluded Races:

Not all races may qualify for BPG. Some bookmakers might exclude specific high profile events, such as large, popular international races.

6. Minimum Bet Requirements:

Some bookies impose a minimum stake requirement for BPG to be applied. This is not common, mind you.

7. Bettor Account Limitations:

Eligibility may be dependent on the bettor’s account status or risk factor. Some bookies restrict BPG from accounts that have been flagged for bonus abuse, professional betting behavior, or because their future expected margin is negative. This allows them to increase their margins.

8. Timing of BOG:

Many bookies specify a cutoff time for BOG offers, such as after 8 AM or 9 AM on race day.

Avoid disappointment. Always check the Terms & Conditions section on the bookmaker’s website to ensure you’re familiar with their BPG specifics, as they can vary slightly between operators.

Advanced Blackjack Strategy

Genghis · January 10, 2010 ·

If you’ve already mastered basic blackjack strategy and fundamental blackjack lingo, it’s time to step up and learn some advanced techniques to lift your game.

Hole Carding in Blackjack

This advanced blackjack tactic refers to gaining knowledge of the cards that are supposed to be hidden from view. This tactic of advantage gambling can only be used in live casinos. The reason hole carding can be an advanced Blackjack strategy is that Blackjack players normally make decisions based on seeing only the dealer’s upcard. However, if a player can spot the dealer’s hole card, this can result in an advantage of up to 13% to the player, as opposed to the normal disadvantage of 0.5%, if a player is using optimal strategy. It goes without saying that if you are attempting this tactic in a live casino, you should ensure to do so as discreetly as possible.

Blackjack card counting techniques

There a number of methods for counting cards. Despite what you may have heard, none of the methods require you to remember cards that have been previously played. Instead, tracking methods are used to count the ratio of unplayed 10’s to smaller cards in the remaining decks. Card counters simply bet more when the deck has a lot of 10’s, which can result in a 1% edge to the player.

There are a number of reasons that counting of 10’s can be advantageous:

Players can choose to hit or stand on a stiff
Dealers must always hit their stiffs
A deck with a lot of 10’s will be more likely to bust a dealer than a player
Small cards lower the probability of winning with a double or a split
Small cards tend to create stiff hands. As a result if both the player and the dealer have a stiff the dealer can beat you by drawing a small card

In summary- blackjack players generally win more when the ratio of 10’s is high. Of course, it goes without saying that a knowledge of fundamental blackjack strategy is essential before trying advanced strategies.

The Hi-Lo Blackjack System – The Harvey Dubner Counting System

The Hi-Lo system is as simple as its name suggests. This system is based on assigning a ranking of +1, 0 or –1 to cards as they fall and the result is an exact measure of how many tens and aces are left in the deck compared to smaller cards. This system is one the most popular system used by Blackjack teams. Once you begin with a new shoe at a Blackjack table, the card count begins at zero.

Card values:
Cards valued at 2,3,4,5, or 6 are counted as +1
7, 8 and 9 are counted as 0
10’s and Aces are counted as –1

Based on the above, for every deck that is used in the shoe there are 20 small cards (2-6), 12 neutral cards (7-9) and 20 high cards (Aces and 10’s). This means that the system is balanced as once every card is counted you would end up with a count of zero. When a lower number of smaller cards are in the deck the advantage is with the player as the odds of winning are higher. A common advanced blackjack strategy used by card counters is to use a spread based on the count whereby stakes are increased when the advantage is with the player.

5:1 bet spread for HiLo card counting

Card count Bet Player advantage
0 or negative Standard stake -1%
+1 Standard stake 0%
+2 Stake X2 0.5%
+3 Stake X3 1%
+4 Stake X4 1.5%
+5 Stake X5 2% or more

Multiple decks and card counting

The Casino’s first line of defence against advanced blackjack strategy and card counters is multiple decks. With six to eight decks, the swings are generally not so extreme. While four tens missing from a single deck would be a big deal, the same cannot be said with a four deck shoe. In order to counteract this measure, the running count is divided by the number of decks that have not yet been played. E.g. the running count of +3 is only +1.5 when two decks are left and only +0.5 when six decks are left in the shoe.

Blackjack Terminology – don’t feel lost at the table

Genie · January 10, 2010 ·

When building your knowledge of basic blackjack strategy or advanced blackjack strategies, it’s critical to get up-to-speed with the lingo of the game so you don’t feel lost at the table.

This refers to the amount of money that is staked or wagered in a Blackjack game. High wagering means more action.

Advantage player:

An advantage player is a person who uses strategy/ and or card counting techniques to gain a mathematic advantage over the house.

Bankroll:

This refers to the amount of money set aside for gambling. In order to deal with the inevitable swings that occur when playing Blackjack, a player must have a sufficient amount set aside for play.

Burn:

The dealer will remove one or more cards from the top of the deck after shuffling. This is referred to as the burn.

Colour up:

Colouring up refers to exchanging chips of a lower value for those of a higher value.

Comps:

Comps are complimentary rewards or bonuses given to loyal players.

Continuous shuffling machine:

A Continuous shuffling machine automatically shuffles used cards back into the deck. This makes card counting impossible.

Blackjack counter measures:

Casino tactics that are used to reduce the effects of various Blackjack strategies. Examples of these are multiple decks, continuous shuffling machines and hitting on soft 17.

Double down:

By doubling down you are placing an additional bet, which is usually an amount equal to your original wager. The dealer will give you exactly one more card and that is your hand. No further hits are allowed and doubling down is usually restricted to the first action on your original hand.

Gambler’s fallacy:

Gambler’s fallacy refers to the myth that past results affect the current contest.

Genie says: Nice work, you’re half way through the blackjack terminology guide!

Handle:

Handle refers to the amount of money that is cycled through a game. Many online casinos offer handle related bonuses whereby when the player meets a specific handle amount, then the bonus will be released.

Hard hand:

A hard hand is a Blackjack hand of 12 or more that doesn’t contain an Ace or has an Ace counted as one. Hard hands between 12 and 16 are often referred to as stiff hands.

Hit:

Basic Blackjack Strategy – stack the odds in your favour

Genie · January 10, 2010 ·

Blackjack Basic Strategy actually refers to the blackjack strategy developed in 1956 by four mathematicians. Roger Baldwin, Herbert Maisel, Wilbert E. Cantey and James P. McDermott were the first group of people to publish their probability based theory on Blackjack “The optimum strategy in Blackjack”. This was published in the Journal of the American Statistical Association and has since been tested, refined and modified through computer simulations. Basic blackjack strategy should be the starting point for every optimal game and is used by all professional Blackjack players. Before diving in, it’s a good idea to start with an understanding of blackjack terminology. Then revisit Genie’s basic strategy guide.

Using Basic Blackjack Strategy

Basic Blackjack Strategy is easy to use. Essentially, it suggests the most appropriate action depending on every possible outcome. While initially basic strategy may appear complicated, it’s actually quite simple. Nearly 50% of the hands should always be played the same way while there are a number of exceptions that should be played in one of two ways depending on what up-card the dealer is showing.

Genie’s shortcuts to Basic Blackjack Strategy

When to stand (“Pat hands”):

Always stand on 19 or higher.
Always stand on hard 17 and hard 18 (except for a pair of nines as per the splitting strategy below).

When to hit:

Always hit on a hand of 8 or less (except for pairs as per the suggestion below).

Splitting/ What to do when you have pairs:

Hands of A,A or 8,8 should always be split.
Hands of 5,5 or 10,10 should never be split.
9,9: Split this hand when the dealers up card is 2-6 or 8-9. Stand against 7, 10 and Ace.
7,7: Split these when the dealers up card is 2-7. Hit against 8 or better.
6,6: Split these against 2-6. Hit against 7 or better.
4,4: Slit against 5 and 6 and hit against anything better.

Doubling down:

There are two main types of doubling situations- hands that total 9, 10 or 11, and soft hands that aren’t “ pat”(don’t require any action- see when to stand). At all times the dealer’s up card will determine whether a hand should be doubled or whether you should hit. Standing is never an option where there is an option for a double. In these instances you should always hit or double.

11: Double against everything except an Ace. Hit against the Ace.
10: Double against everything except 10 and Ace. Hit against 10 and Ace.
9: Double against 3-6. Hit against everything else.
Soft hands: Soft hands that aren’t pat are always hit or doubled. The only exception is soft 18.
A,7: Double a soft 18 against 3-6. Stand against 2, 7 or 8. Hit against 9 or better.
A,6: Double against 2-6 and hit against everything else.
A,5 and A,4: Double against 4,5 and 6. Hit against everything else.
A,2 and A,3: Double against 5 and 6 and hit in all other situations.
Stiff hands (hard hands between 12-16): Always hit a stiff hand when a dealer has 7-A. Never hit a stiff hand when a dealer has 2-6 except for the below:
- 16: surrender against 9,10 or Ace or hit if surrender isn’t allowed
- 15: surrender against 10, hit if surrender isn’t allowed
- 12: hit against a 2 or 3

Genie says: All doubling down situations are positive-expectation situations so ensure to optimise your game by doubling down where possible.
