1-2-3-5 Betting Strategy in Blackjack Explained
Through the years, the world of casinos has seen numerous gamblers, mathematicians, and other interesting characters devise betting systems that they believe offer the best chance at finding some winnings against the house. The 1-2-3-5 betting strategy is one of those meant to give players the chance at winning more if things go their way at the blackjack tables.
This is a simple positive progressive betting system that can bring some solid results during winning streaks by offering a structured way to scale bets based on wins and losses. But like all betting systems, there are some downsides and this article offers a complete look at how the blackjack betting strategy 1-2-3-5 works and how one can implement the system when playing.
What is the 1-2-3-5 Blackjack Betting Strategy?
The 1-2-3-5 blackjack betting strategy features a regimented betting sequence that sees players increase their bets by multiples of 1, 2, 3, and 5 when winning and then return to the initial wager unit after losing or finding four wins in a row.
- For example, suppose you begin a blackjack hand with a $5 wager and win. The next bet would then be $10 ($5 x 2). If you win that bet, the wager then goes to $15 ($5 x 3). If that bet also turns out well, you’d then make a bet of $25 ($5 x 5). If you win those four bst in a row or lose a single wager, then the bet returns to the minimum of $5. The four wins in a row has yielded a nice profit while getting the player back to the original smaller betting unit.
How the 1-2-3-5 Strategy Works in Blackjack
The 1-2-3-5 betting strategy is a progressive betting system, meaning that the wager typically restarts after a win or a loss. Progression systems can help manage risk while maximizing returns.
In the above series of four hands, if you had won four straight bets in this sequence, that would yield a profit of $55. That’s not a bad return on investment for four bets at just $5. Here’s a quick look at how the wager above would play out.
| Sequence | Bet | Profit |
| 1 | 1 unit | 1 unit |
| 2 | 2 units | 2 units |
| 3 | 3 units | 3 units |
| 5 | 5 units | 5 units |
| TOTAL | 6 units | 6 units |
It’s important to note that this profit can go up if the player is dealt a blackjack during this sequence of four bets. But at any time during these four bets, had the player lost a hand the wager the bet returned back to the initial starting amount of $5 and a new sequence could begin again.
Advantages of the 1-2-3-5 Blackjack Strategy
As outlined above, if the player won all four wagers that would be a profit of 11 of the original units wagered, $5 in this case. One advantage is that simply winning three bets also means a profit of at least two units (possibly a bit more if one or both of those hands were blackjacks).
Players can maximize returns when they are finding some winning streaks, while also minimizing losses as the bet eventually returns to one unit after significant wins or a single loss. There are other advantages to the 1-2-3-5 blackjack strategy including:
- Structured risk management – This helps a player manage their bankroll because the wagers don’t get too large.
- Reducing large losses – Not getting too overleveraged with larger bets can help make sure you’re not losing too much.
- Having a clear betting plan – Players have a definite game plan going into every hand.
Limitations of the 1-2-3-5 Betting System
While there are some advantages to the blackjack 1-2-3-5 strategy, there are also some disadvantages. Here’s a look at a few of those:
- An over-reliance on streaks – This system maximizes wins when a player wins a few hands in a row, but as any gambler knows, wins can be very inconsistent at times.
- Losses still occur – Players may still experience significant losing streaks to offset any wins.
- Bankroll issues – Players experiencing losses may not be able to stretch the bankroll for a longer session. This is especially true if a player chooses a minimum unit is too large a percentage of the overall bankroll.
Like any betting system, the 1-2-3-5 betting strategy cannot guarantee wins and players must have realistic expectations in this regard. However, the strategy can be a regimented approach to gaming and could pay off if you find some winning streaks at the blackjack table.
Practical Tips for Using the 1-2-3-5 Strategy Effectively
Looking to work the 1-2-3-5 strategy into your own blackjack play? It’s important to get the sequence down and also find a betting unit that best fits your bankroll. It’s also key to set a limit. If you win a certain amount, that may be time to walk away a winner. On the other hand, know when to cut your losses and leave the table.
Using basic strategy is always key to giving yourself the best mathematical chance of winning a hand based on the situation and the dealer’s upcard. Also, choose tables with favorable rules to ensure yourself the best chance at reducing the house edge as much as possible.
Having some real discipline is also key when utilizing the 1-2-3-5 blackjack strategy. Going beyond the four winning wagers and not returning back to the initial unit puts that bankroll more at risk and can mean losing the funds you’d profited with the winning streak. Raising your bets randomly also affects your chances of winning by introducing arbitrary moves into what is meant to be a regimented system.
