Union Jack Trixie Calculator

Work out the returns on a Union Jack Trixie: nine selections in a 3x3 grid with each of the eight lines played as a Trixie.

A Union Jack Trixie calculator works out the returns on nine selections arranged in a 3×3 grid where each of the eight lines is played as a four-bet Trixie, totalling thirty-two bets in decimal odds.

What Is a Union Jack Trixie?

A Union Jack Trixie takes nine selections in a three-by-three grid and plays each of the eight lines (three rows, three columns, and two diagonals) as a separate Trixie. A Trixie consists of three doubles and a treble from three selections, so when each of the eight lines becomes a Trixie, the whole thing runs to thirty-two bets. The defining feature of this variant is that a line now pays with only two of its three selections winning rather than needing all three. Where a plain Union Jack Trebles demands all three selections on a line to land, a Union Jack Trixie can cash part of the stake from two-selection doubles, making near-misses pay. This matters because nine-selection grids rarely come in whole, so the downgrade from three to two winners creates returns on outcomes that a straight treble union would lose.

The flexibility matters because most nine-selection outcomes are partial. Four or five winners scattered across the grid, or two tight clusters — in these scenarios a Union Jack Trebles pays nothing. A Trixie collects from every line containing two winners, meaning more returns on partial hits. The cost is the bet grows to thirty-two instead of eight, making it four times larger.

How a Union Jack Trixie Is Calculated

The calculation starts with the grid. Nine selections fill a three-by-three matrix, creating eight lines: three horizontal rows, three vertical columns, and two diagonals. Each line forms its own Trixie, which means each line contains three doubles and one treble made from its three selections. Three doubles from three selections give three ways to choose two of them — one double for the first two selections, one for the first and third, one for the second and third. Add the treble of all three and you have four bets per line. With eight lines, that totals thirty-two bets.

Every bet is placed at the chosen unit stake, so if the unit stake is EUR 0.50 and there are thirty-two bets, the total outlay is EUR 16.00. The position of each selection on the grid determines how many lines it affects. Centre selections sit in four lines — one row, one column, and two diagonals — making them the most influential square. Corner selections sit in three lines each. Edge selections sit in five lines each. When a selection wins, it pays on every Trixie line it belongs to, because those lines will have multiple bets with that selection winning. When a selection loses, the whole line it sits on loses, because the treble on that line fails and all the doubles containing that selection also fail. The calculator sums the returns from all thirty-two Trixies and shows the total.

Void selections recalculate the affected lines. A voided selection turns its line’s treble into a double using the remaining two selections, so the line remains in play at reduced odds.

What the Calculator Shows You

Enter nine decimal odds and a unit stake, and the calculator returns the total payout if all selections win, the total profit, the implied probability across the whole grid, and a line-by-line breakdown. Total return shows the cash payout from all thirty-two bets if every selection wins. This is the gross amount returned, including your stake back. Total profit strips out the outlay to show your net gain — the amount you are actually up if the bet lands. Implied probability converts the whole grid’s combined odds into a percentage, useful for checking whether the complexity and size of the commitment feels like value relative to your own assessment of the selections landing together.

The line breakdown shows which lines would cash at each outcome. When you mark selections as Won, Lost or Void, the calculator updates each line’s status, so you see exactly how a partial outcome would settle. This is crucial on a nine-leg grid where perfect outcomes are rare — most bets end partial, so the breakdown guides tracking and shows how dependent the bet is on key selections.

Worked Example

Take a nine-selection Union Jack Trixie on La Liga matches with a EUR 0.50 unit stake. The grid holds Real Betis to win at 1.40, Sevilla to win at 2.10, Valencia to win at 1.70, Villarreal to win at 1.90, Athletic Bilbao to win at 1.60, Real Sociedad to win at 2.30, Celta Vigo to win at 2.00, Getafe to win at 1.50, and Osasuna to win at 2.40.

The total outlay is 32 bets at EUR 0.50 each, which equals EUR 16.00. If all nine selections win, the combined odds work through all thirty-two Trixies and return EUR 65.78 for a profit of EUR 49.78. That return reflects the shortest price in the grid (Getafe at 1.50) and the longest (Osasuna at 2.40), with the other selections weighing in between. Even three-leg accumulators on these same prices would return far less from the same EUR 16.00 outlay because most combinations hit one loser and collapse entirely. In a Union Jack Trixie, so long as any two selections from a given line win, that line’s doubles pay. This is why a grid of mixed-odds selections is tractable: unlikely outcomes like all nine winning are rare, but two or three winners across the grid return something from multiple lines.

The Eight Union Jack Lines and Their Treble Odds

The grid creates eight distinct lines. Each one has a treble combining its three selections, shown here for reference. The doubles within each line pay at fractional odds depending on which two selections land.

Union Jack Trixie Outlay at Different Unit Stakes

The total cost of a Union Jack Trixie is always thirty-two times the unit stake you choose. The higher the unit stake, the larger your commitment across all bets.

Two-Winner Payouts in Union Jack Trixies

The upgrade from trebles to Trixies changes what counts as a result. In a plain Union Jack every line needs all three of its selections to cash; here two are enough to collect a double. That fundamental shift makes near-misses pay, which matters because a nine-selection grid rarely comes in whole. The economics of this change are stark. Imagine a scenario where exactly five of your nine selections win. In a Union Jack Trebles, very few lines hit all three, so the return is minimal or zero depending on how the winners land. In a Union Jack Trixie, those five winners create numerous two-winner combinations across the grid, and each pair that shares a line pays its double. Over nine selections, partial hits that would produce nothing in a treble version become productive, sometimes substantially so.

The cost, however, is that the bet grows to thirty-two bets instead of eight — four times larger for the same unit stake. That means the same unit stake buys a much larger commitment to the grid. The centre selection sits in four of the eight lines, so whatever it does magnifies through the bet. A losing centre pick can wipe out four of your eight line chances, but a winning centre pick strengthens four lines at once. The edges and corners sit in fewer lines, making their impact more focused but narrower. Void selections change only their lines: a voided centre removes four lines entirely while a voided corner impacts only three, so the structural position matters not just for winners but also for runners that fail to get a race.

When a Union Jack Trixie Makes Sense

A Union Jack Trixie is a high-variance grid bet that works when you have genuine conviction in a cluster of nine selections rather than a single standout. It suits bettors who want to see some return from partial hits on a nine-leg play but accept the large outlay and complexity that comes with thirty-two bets. Choose a Trixie version if you rate the selections highly enough to back them as part of a multiple, but not so confidently that you need all nine to win. The threshold is roughly: if you would not back five or six of these selections together as smaller multiples, do not put all nine in a grid.

Bankroll management is crucial. A EUR 1.00 unit stake commits EUR 32.00 total, which is substantial. Many grid bettors underestimate their exposure and choose stakes too high relative to their bankroll. A good rule is to treat the full outlay — not the unit stake — as your commitment. If you set EUR 0.25 per unit, that is EUR 8.00 total. EUR 0.50 is EUR 16.00. EUR 1.00 is EUR 32.00. Make sure the full outlay fits your bankroll and your tolerance for losing it. The centre square matters most because it affects the most lines; placing your best-fancied selection there lets its success compound across four lines. Conversely, placing a weak pick in the centre can drag down four lines at once, so be disciplined about which selections earn the centre spot. The doubles payouts mean the bet works harder than a treble union at the same outlay, but that benefit evaporates if too many selections lose — in any nine-leg bet, variance is high and downswings happen regularly.

Common Mistakes

The most frequent error is setting a unit stake without multiplying by thirty-two; bettors often assume the bet costs the unit stake alone and are shocked by the full outlay. Others assume a Trixie line pays on one winner when it still needs two to collect the doubles. Many compare the outlay with a plain Union Jack without noting that a Trixie version is four times larger in number of bets. Finally, ignoring grid position is costly: the centre selection decides the fate of four of your eight lines, while corners and edges affect only three or five respectively, so placement of your strongest conviction matters far more than in a straight treble union.

Union Jack Trixie vs Other Union Jack Variants

Union Jack Trixie differs fundamentally from the other grid variants in how many selections each line needs to pay.
