Although considered an old-school wager, the Union Jack has experienced a revival in recent years. But what is a Union Jack bet and where did it come from?
A Union Jack bet is a type of multiple bet based on nine selections arranged in a 3×3 grid. The number of bets range from 8 and 80 – depending on the type (four different variations are available) – and are determined by drawing lines vertically, horizontally and diagonally to find eight groups of three bets. The bet encompasses various combinations including Trebles, Trixies, Patents and Round Robins.
In this article, we’ll take a deep dive into Union Jack bets, exploring all the different types and how they work. We’ll then move on to a step-by-step of how to place a Union Jack, and explain the importance of strategic Union Jack betting.
How Does a Union Jack Bet Work?
The Union Jack bet follows the layout of the Union Jack and uses a 3×3 grid system with nine selections.
Combinations are then created using patterns in the grid. Lines are formed horizontally, vertically, and diagonally to create different bet combinations. The table below provides a basic example of a Union Jack layout.
| Bet A | Bet B | Bet C |
| Bet D | Bet E | Bet F |
| Bet G | Bet H | Bet I |
Depending on the type of Union Jack Bet selected (Treble, Trixie, Patent or Round Robin), the grid can be used to create between 8 and 80 different bets under one wager.
What are the Different Types of Union Jack Bet?
The four different types of Jack Bets are the Union Jack Treble, Trixie, Patent and Round Robin.
| Union Jack Bet Type | Total Number Of Bet | Bet Types |
| Union Jack Treble | 8 | 8 Trebles |
| Union Jack Trixie | 32 | 8 Trixies (8 Trebles, 24 Doubles) |
| Union Jack Patent | 56 | 8 Patents (8 trebles, 24 doubles & 24 singles) |
| Union Jack Round Robin | 80 | 8 Round Robins (8 trebles, 24 doubles, 24 singles & 24 SSA pairs) |
Each of the different Union Jack bets uses the 3×3 grid system to form any winning combination numbers. Whether it’s a full or partial win, bettors can expect a return when three or more selections settle as a win.
Union Jack Trebles
A Union Jack Treble is the simplest form of Union Jack bet and contains a total of 8 different wagers (trebles) within the multiple.
If you take another look at the 3×3 grid we provided earlier, the eight Union Jack Trebles bets would be as follows:
- ABC (Bet A, Bet B & Bet C)
- DEF (Bet D, Bet E & Bet F)
- GHI (Bet G, Bet H & Bet I)
- ADG (Bet A, Bet D & Bet G)
- BEH (Bet B, Bet E & Bet H)
- CFI (Bet C, Bet F & Bet I)
- AEI (Bet A, Bet E &Bet I)
- CEG (Bet C, Bet E & Bet G)
Any winning combination of these ABC, DEF, etc. will result in a return for the bettor. A free bet calculator is often the best way to understand the specifics (all bets apart from G, H and E settle as a win, for example).
Example of a Union Jack Trebles Bet With Possible Outcomes
To explain the intricacies of a Union Jack Bet, it can be beneficial to use a real-world example. In the example below, we have chosen nine different horses from an upcoming day of racing.
| Inspiral (5/1) | Ranko Express (9/2) | See Me Through (4/1) |
| Bad Desire (4/7) | Nostringsattached (9/4) | Our Lil (10/3) |
| Settlement (6/5) | Ocean Of Dreams (2/1) | Hanoi (5/2) |
To simplify the numbers, we are using £1 per bet (or £8 in total staked).
- ABC (Inspiral, Ranko Express & See Me Through) = 5/1 x 9/2 x 4/1 = £165.00
- DEF (Bad Desire, Nostringsattached & Our Lil) = 4/7 x 9/4 x 10/3 = £22.13
- GHI (Settlement, Ocean Of Dreams & Hanoi) = 6/5 x 2/1 x 5/2 = £23.10
- ADG (Inspiral, Bad Desire & Settlement) = 5/1 x 4/7 x 6/5 = £20.74
- BEH (Ranko Express, Nostringsattached & Ocean Of Dreams) = 9/2 x 9/4 x 2/1 = £53.63
- CFI (See Me Through, Our Lil & Hanoi) = 4/1 x 10/3 x 5/2 = £20.68
- AEI (Inspiral, Nostringsattached & Hanoi) = 5/1 x 9/4 x 5/2 = £68.25
- CEG (Settlement, Nostringsattached & See Me Through) = 6/5 x 9/4 x 4/1 = £35.75
If all nine individual selections settle as a win, you would return £409.28 from an £8 total stake.
Understandably, this format becomes confusing once one or several horses fail to win or place. To accurately calculate all different outcomes, we recommend using a Union Jack Trebles free bet calculator – available online.
Union Jack Trixie
The Union Jack Trixie bet amplifies the standard Union Jack Treble by including the maximum number of doubles (hence the Trixie name).
| Bet A | Bet B | Bet C |
|---|---|---|
| Bet D | Bet E | Bet F |
| Bet G | Bet H | Bet I |
In addition to the eight Union Jack Trebles bets, as highlighted above, each Treble is then broken down into an additional three doubles. For example:
- ABC (Bet A, Bet B & Bet C), AB (Bet A & Bet B), BC (Bet B & Bet C) & AC (Bet A & Bet C)
This is continued for all other combinations, leading to a total of 8 trebles and 24 doubles.
Example of a Union Jack Trixie Bet With Possible Outcomes
Using the same example of an upcoming day of the races, we can analyse the top row (ABC), to illustrate the power of the Union Jack Trixie. We’ll start by analysing the outcome when each selection wins.
| Inspiral (5/1) – Won | Ranko Express (9/2) – Won | See Me Through (4/1) – Won |
Again, for simplification, we are using £1 per bet (or £4 in total staked for the row).
- ABC (Inspiral, Ranko Express & See Me Through) = 5/1 x 9/2 x 4/1 = £165
- AB (Inspiral & Ranko Express) = 5/1 x 9/2 = £33
- BC (Ranko Express & See Me Through) = 9/2 x 4/1= £27.50
- AC (Inspiral & See Me Through) = 5/1 x 4/1= £30
Total winnings are £255.50 from a £4 total stake for this row.
Next, we’ll take a look at the outcomes when just one selection of the three settles as a loss.
| Inspiral (5/1) – Won | Ranko Express (9/2) – Won | See Me Through (4/1) – Lost |
With £1 per bet:
- ABC (Inspiral, Ranko Express & See Me Through) = 5/1 x 9/2 x 4/1 (Lost) = £0
- AB (Inspiral & Ranko Express) = 5/1 x 9/2 = £33
- BC (Ranko Express & See Me Through) = 9/2 x 4/1 (Lost) = £0
- AC (Inspiral & See Me Through) = 5/1 x 4/1(Lost) = £0
Total winnings are just £33 from a £4 total stake for this row.
The Union Jack bet gets more complex with each additional level, so again we recommend that you use a Union Jack Trixie free bet calculator.
Union Jack Patent
The Union Jack Patent consists of the same nine selections, only this time there are 56 individual bets included – eight trebles, 24 doubles and 24 singles. It takes the Union Jack Trixie and elevates it once more.
| Bet A | Bet B | Bet C |
|---|---|---|
| Bet D | Bet E | Bet F |
| Bet G | Bet H | Bet I |
Each line of the Union Jack, as highlighted above, is then broken down into a patent bet comprised of three single bets, three doubles and one treble. For example:
- ABC (Bet A, Bet B & Bet C)
- AB (Bet A & Bet B), BC (Bet B & Bet C) & AC (Bet A & Bet C)
- A (Bet A), B (Bet B) & C (Bet C)
Using a Union Jack Patent calculator is invaluable at this level – with 56 individual bets, manually calculating the outcome becomes time-consuming.
Example of a Union Jack Patent Bet With Possible Outcomes
Using the same example as above, we can analyse the top row (ABC), to illustrate the power of Union Jack Patent. We’ll start by analysing the outcome when each selection wins.
| Inspiral (5/1) – Won | Ranko Express (9/2) – Won | See Me Through (4/1) – Won |
To simplify the numbers, we are using £1 per bet (or £7 in total staked for this row).
- ABC (Inspiral, Ranko Express & See Me Through) = 5/1 x 9/2 x 4/1 = £165
- AB (Inspiral & Ranko Express) = 5/1 x 9/2 = £33
- BC (Ranko Express & See Me Through) = 9/2 x 4/1= £27.50
- AC (Inspiral & See Me Through) = 5/1 x 4/1= £30
- A (Inspiral) = 5/1 = £6
- B (Ranko Express) = 9/2 = £5.50
- C (See Me Through) = 4/1 = £5
Total winnings are £272.00 from a £7 total stake for this row.
Next, we’ll take a look at the outcomes when just one selection of the three settles as a loss, again using £1 per bet.
| Inspiral (5/1) – Won | Ranko Express (9/2) – Won | See Me Through (4/1) – Lost |
- ABC (Inspiral, Ranko Express & See Me Through) = 5/1 x 9/2 x 4/1 (Lost) = £0
- AB (Inspiral & Ranko Express) = 5/1 x 9/2 = £33
- BC (Ranko Express & See Me Through) = 9/2 x 4/1 (Lost) = £0
- AC (Inspiral & See Me Through) = 5/1 x 4/1(Lost) = £0
- A (Inspiral) = 5/1 = £6
- B (Ranko Express) = 9/2 = £5.50
- C (See Me Through) = 4/1 (Lost) = £5
Total winnings are just £44.50 from a £7 total stake for this row.
A Union Jack patent bet calculator is simply a must at this point.
Union Jack Round Robin
The final and most powerful Union Jack is the Round Robin – a multiple bet which contains a huge 80 different bet combinations. The Round Robin takes the Union Jack Patent example and elevates it again, adding 24 Up-And-Down SSA (Single Stakes About) Pairs.
The Up-And-Down SSA (Single Stakes About) Pairs are the only difference between the Union Jack Round Robin and the Union Jack Patent bet. Consisting of two bets, each SSA is split into two components:
- Bet 1:
- Part 1: Bet on selection A.
- Part 2: Bet on selection B if sufficient cash is left from part A.
- Bet 2:
- Part 1: Bet on selection B.
- Bet on selection A if sufficient cash is left from part A.
Example of a Jack Round Robin Bet With Possible Outcomes
Using the same example as above, we can analyze the top row (ABC), to illustrate the power of Union Jack Patent. We’ll start by analyzing the outcome when each selection wins.
| Inspiral (5/1) – Won | Ranko Express (9/2) – Won | See Me Through (4/1) – Won |
| Bad Desire (4/7) – Lost | Nostringsattached (9/4) – Lost | Our Lil (10/3) – Lost |
| Settlement (6/5) – Lost | Ocean Of Dreams (2/1) – Lost | Hanoi (5/2) – Lost |
With a Round Robin Union Jack bet with the above configuration, the total return from the £80 outlay (£1 per bet) would be £543.00.
The mathematics required is too lengthy to denote by hand. Use a free Union Jack Round Robin calculator to calculate the outcome.
Why is the Placement Crucial?
The placement of a Union Jack Bet is crucial as this is what permits the available combinations and determines the chances of winning. Losing bets in GEC will cause much more damage to a Union Jack Bet than ABC. Ensure that the strongest selection forms the centre of the bet and workaround for the best chance of a quality return.
How Do You Calculate the Returns?
The returns of a Union Jack bet can be calculated by hand using the above methods – although this is often a laborious task.
To save time, effort and brain power, A Union Jack bet calculator or payout calculator can be used to calculate your potential winnings.
