A system bet can fund several separate combinations from one set of selections. With the same amount on every line, total stake equals the number of funded lines multiplied by that unit amount. A small per-line figure can therefore produce a much larger account debit. Check the confirmed components and total, rather than reading the unit as the whole purchase price.
This reference connects our detailed guides to named multiple-bet formats. It concentrates on the cost and receipt structure, with a new five-selection example. Operator definitions and British display requirements were checked on 27 October 2026. The prices, stakes and results below are invented ordinary cash-bet illustrations, not offers, tested account transactions or a method for making money.
Identify the funded combinations
Start with three quantities: the number of distinct eligible selections, the size of each combination and the amount allocated to each line. Five selections do not tell you whether the ticket contains five singles, ten trebles, one fivefold or several sizes together.
Betfair's bet-type reference describes permutation betting as combining selections into a chosen size of multiple. It also defines named packages, including a Canadian with five selections and 26 component bets. Those are different purchases. A label saying system should lead to a component breakdown, not an assumption that every possible line was included.
An ordinary treble joins three selections in one bet and requires all three to succeed under the simple win-only model. Reordering A, B and C does not create another independently funded ABC treble. Conversely, ABC and ABD are different combinations even though they share two selections.
Our round-robin guide explains subset counting and the different products sold under that name. The important receipt question here is which subset sizes were actually accepted. Do not add unpurchased singles or assume that an omitted combination has somehow been insured.
Compare the same selections at the same unit
For five eligible selections, choosing every group of three creates ten distinct lines. Mathematically, C(5,3) = 5! / (3! × 2!) = 10. This counts each unordered group once. It does not establish that a particular operator will accept every proposed combination.
The table fixes an invented 40p stake on each funded line. The Canadian and Lucky 31 structures follow the named operator definitions; the other rows are deliberately specified constructions. The amounts are calculated by BetTimes, not advertised minimum stakes or available offers.
| Construction from five selections | Sizes funded | Number of lines | Total at 40p per line |
|---|---|---|---|
| Singles only | One selection per line | 5 | £2.00 |
| One fivefold only | All five in one line | 1 | £0.40 |
| All trebles only | Every group of three | 10 | £4.00 |
| Canadian | Doubles, trebles, fourfolds and fivefold | 26 | £10.40 |
| Lucky 31 | Singles plus those multiple sizes | 31 | £12.40 |
The fivefold row is not a cheaper version of the same ten-line purchase. It funds a different outcome condition. Nor does the Canadian's higher line count establish that it is better value: it commits more money at that unit, while possible payments depend on prices and results.
For smaller named packages, use the dedicated Trixie and Patent explanation and Yankee and Lucky 15 comparison. Their full result tables belong with those formats. Changing the number of selections or adding singles changes the funded set; do not carry one package's total into another.
Check whether the input is a unit or a budget
Sky Bet's bet-type help explains that multi-unit types multiply the stake by the number of component bets. That is a useful check on the meaning of the amount entered. It is not evidence that every interface uses the same input convention.
In the ten-treble construction, 40p on each line costs £4. A £4 whole-ticket budget distributed equally over those same ten lines would also allocate 40p to each. Entering £4 per line would instead commit £40. The number is identical; the field's meaning changes the cost by a factor of ten.
If an interface allocates a whole-ticket total, check the resulting component stakes and any rounding. If different lines carry different amounts, add their actual stakes rather than using one unit for all of them. A confirmation showing £4 total should not be multiplied by ten again.
For covered British remote gambling, RTS 2 requires clear information about the money being gambled and the content of the gamble before commitment. Its guidance specifically identifies unit and total stake where appropriate, alongside relevant selection, bet-type and accepted-odds information. This is a British display requirement, not a certification that a given ticket complies or a promise of a refund when a display is disputed.
Retain the final acknowledgement and the debit, not just a screenshot of an unfinished slip. If the unit and total cannot be reconciled, ask the operator to explain the accepted components before interpreting a later return.
Ten trebles can pay and still lose money
Consider five fictional selections A, B, C, D and E on separate eligible events. Buy all ten trebles at 40p each, spending £4. Assume each selection has accepted decimal odds of 2.00. A, B and C win normally; D and E lose. Every line is cash-funded and win-only.
Only ABC contains three winners. Its gross return is £0.40 × 2.00 × 2.00 × 2.00 = £3.20, including that line's stake. Every other purchased treble includes D or E and returns zero in this model.
| Funded treble | Result under the invented A/B/C-win, D/E-lose scenario | Gross return from its 40p stake |
|---|---|---|
| ABC | All three win | £3.20 |
| ABD | D loses | £0.00 |
| ABE | E loses | £0.00 |
| ACD | D loses | £0.00 |
| ACE | E loses | £0.00 |
| ADE | D and E lose | £0.00 |
| BCD | D loses | £0.00 |
| BCE | E loses | £0.00 |
| BDE | D and E lose | £0.00 |
| CDE | D and E lose | £0.00 |
The ticket's total return is £3.20. Subtract the entire £4 outlay to obtain a loss of 80p. Subtracting only ABC's 40p would describe that winning line's profit, while ignoring the stakes spent on the other nine lines. It would not describe the ticket's net result.
If only A and B won, none of these trebles would qualify and the full £4 would be lost. Those are conditional arithmetic cases, not probabilities or equally likely outcomes. No bonus, each-way component, void, dead heat, tax, deduction, cash out or payout cap is included.
Reconstruct the accepted ticket before changing the count
Betfair's general Sportsbook rules distinguish Fixed Odds Multiples from Same Game Multiples. They allow rejection or stake reduction, and their stated fixed-odds treatment adjusts a multiple containing a void leg. Sport-specific conditions still matter. This does not establish an identical rule for other operators or Exchange offers.
A void is therefore not a losing result to insert into the ten-line table. Nor should reduced combinations automatically be treated as one new ticket with a freshly calculated line count. Retain the original funded lines and request the applicable adjustment. Our maximum payout versus maximum stake guide addresses a separate limit on the amount accepted or payable.
For an unexplained debit or settlement, keep these records together:
- The product, currency, ticket identifier, bet type and complete selection list.
- The accepted combination sizes and funded lines, including any rejected or reduced portion.
- Each component stake, the total debit and whether the input was a unit or a whole-ticket budget.
- The accepted prices, settled outcomes and rule for any exceptional result or promotion.
- The component returns and their sum, with net profit or loss calculated against the complete original outlay.
Ask for a line-by-line reconciliation when the amounts disagree. A maximum potential return displayed before results is not money already earned. These formats do not improve the underlying chance of a selection winning or guarantee recovery of the stake. The full amount committed can be lost.
Frequently asked questions
Do five selections mean five bets?
Only if the accepted construction funds five lines, such as one independent single on each. The example here buys ten different trebles from those same five selections. One fivefold would be one line, while a named full-cover package can contain several sizes. Read the accepted components before counting the cost.
Is 40p the total stake in the ten-treble example?
No. It is the stake on each of ten lines, so the total is £4. If a screen instead asks for a whole-ticket budget, use its confirmed allocation. Do not assume a per-line input or multiply an already displayed total a second time.
Does a winning combination mean the ticket made a profit?
No. In the fictional example, ABC returns £3.20 but the complete ticket cost £4. The difference is an 80p loss. Keep component profit, total money returned and the full ticket's net result separate when explaining a settlement.
