You stare at the phone. How many lines? How much per line? Which combinations pay?\n\nMost guides published in 2026 dodge the actual math. They describe what a system bet *is*, flash a generic \"use a calculator\" button, and leave you guessing. This guide does the opposite — it walks through the arithmetic end to end, with worked examples, the combinations formula, and the exact sequence to calculate any system bet by hand.\n\nBy the end, you'll be able to look at any slip — 2\u002F3, 3\u002F5, Yankee, Lucky 15, Heinz — and tell a friend what it pays before the final whistle. Or, if you prefer a shortcut, you can drop the numbers into [our free system bet calculator](\u002Fbetting\u002Fsystem-bet-calculator) and let it do the heavy lifting.\n\n## TL;DR — Quick Summary\n\nA system bet payout = **sum of (stake per line × combined odds) across every winning line**. The number of lines is C(n, k) — the combinations formula. Divide your total stake evenly across those lines, then add up what the winners pay.\n\n### The Core Formula in One Line\n\n$$\\text{Payout} = s \\times \\sum_{\\text{winning lines}} (o_1 \\times o_2 \\times \\ldots \\times o_k)$$\n\nPlain English: multiply each winning line's odds together, multiply by your per-line stake, then add up the lines that won. That's the entire mechanic.\n\n### Key Numbers to Memorize\n\n| System | Picks | Lines | Minimum Correct |\n|--------|:-----:|:-----:|:--------------:|\n| 2\u002F3 | 3 | 3 | 2 |\n| 3\u002F4 | 4 | 4 | 3 |\n| Trixie (full cover) | 3 | 4 | 2 |\n| 3\u002F5 | 5 | 10 | 3 |\n| Yankee (full cover) | 4 | 11 | 2 |\n| Lucky 15 (full cover) | 4 | 15 | 1 |\n| 4\u002F6 | 6 | 15 | 4 |\n| Heinz (full cover) | 6 | 57 | 2 |\n| Goliath (full cover) | 8 | 247 | 2 |\n\n## How to Calculate a System Bet in 4 Steps\n\nThis is the template — every system bet in the world follows this exact sequence. Once you've run through it a few times, you'll be able to work through any slip in under a minute.\n\n### Step 1 — List Your Picks and Odds\n\nWrite them out. Seriously — pull out a piece of paper or open a notes app. Label each pick with a letter (A, B, C, D) and write its decimal odds next to it. Example:\n\n- A: Liverpool win @ 2.00\n- B: Man City win @ 1.50\n- C: Arsenal win @ 1.70\n\nDecimal odds are mandatory for this math. If you're on American odds, convert them first (+150 = 2.50, −200 = 1.50). If you're on fractional, convert them too (7\u002F4 = 2.75, 1\u002F2 = 1.50). The formula only works with decimals.\n\n### Step 2 — Work Out How Many Lines\n\nThis is the combinations step. For a k\u002Fn system, the number of betting lines is C(n, k) — the binomial coefficient. We'll get into the formula in the next section, but for memorization:\n\n- C(3, 2) = 3\n- C(4, 2) = 6, C(4, 3) = 4, C(4, 4) = 1\n- C(5, 3) = 10\n- C(6, 3) = 20, C(6, 4) = 15\n\nFor full-cover bets (Yankee, Lucky 15, Heinz), add up multiple C(n, k) values because the bet covers every combination size. A Yankee on 4 picks = C(4,2) + C(4,3) + C(4,4) = 6 + 4 + 1 = **11 lines**.\n\n### Step 3 — Divide Your Stake\n\nYour total stake divided evenly across every line. If you're staking £60 on a 3\u002F5 system with 10 lines, each line carries £6. If you're staking £30 on a 2\u002F3 system with 3 lines, each line carries £10.\n\nSome bookmakers default to \"stake per line\" input instead of \"total stake\" — meaning a £1 stake per line on a Heinz silently becomes £57 total. This trips up beginners constantly. Always confirm which mode the slip is using before tapping place.\n\n### Step 4 — Sum the Winning Combinations\n\nFor every line where all legs won, compute:\n\n$$\\text{Line payout} = s_{\\text{per line}} \\times o_1 \\times o_2 \\times \\ldots \\times o_k$$\n\nAdd them up. Ignore any line where one or more legs lost — that line returns zero.\n\nThat's it. Four steps, no shortcuts, no approximations. The next sections walk through the combinations formula and then show you the math live for a 2\u002F3, a 3\u002F5, and a Yankee.\n\n::chart-system-bet-lines\n::\n\n## The Combinations Formula: nCr Made Simple\n\nEverything in system bet math rests on one piece of high-school combinatorics: the binomial coefficient, written as C(n, k) or \"n choose k\". It answers the question: *from a group of n items, how many distinct groups of size k can I make, if order doesn't matter?*\n\n### What the Formula Actually Says\n\nThe standard formula:\n\n$$C(n, k) = \\binom{n}{k} = \\frac{n!}{k! \\times (n-k)!}$$\n\nIf you've forgotten what factorials are: n! means multiply every integer from 1 to n together. 4! = 1 × 2 × 3 × 4 = 24. Plug it into the combinations formula and it collapses fast.\n\nExample: C(4, 2) = 4! \u002F (2! × 2!) = 24 \u002F (2 × 2) = **6**. So a 2\u002F4 system bet creates 6 lines. Every possible pair from ABCD: AB, AC, AD, BC, BD, CD. Six pairs, six lines.\n\nFor small n and k, you can just list the pairs by hand. For anything above about C(5, 3), use the formula (or our [universal system bet calculator](\u002Fbetting\u002Fsystem-bet-calculator), which handles every format from 2\u002F3 to Goliath).\n\n### Combinations Table for Every System\n\nHere's the cheat sheet — every combination count you'll realistically need, in one table.\n\n#### Small Systems (3–5 Picks)\n\n| n picks | Pairs C(n,2) | Trebles C(n,3) | 4-folds C(n,4) | 5-folds C(n,5) |\n|:-------:|:------------:|:--------------:|:--------------:|:--------------:|\n| 3 | 3 | 1 | — | — |\n| 4 | 6 | 4 | 1 | — |\n| 5 | 10 | 10 | 5 | 1 |\n\nSo a 3\u002F5 system = C(5, 3) = **10 lines**. A Yankee (full cover on 4 picks) = 6 + 4 + 1 = **11 lines**. A Lucky 15 adds 4 singles to the Yankee structure: 4 + 6 + 4 + 1 = **15 lines**.\n\n#### Large Systems (6–8 Picks)\n\n| n picks | Pairs | Trebles | 4-folds | 5-folds | 6-folds | 7-folds | 8-folds |\n|:-------:|:-----:|:-------:|:-------:|:-------:|:-------:|:-------:|:-------:|\n| 6 | 15 | 20 | 15 | 6 | 1 | — | — |\n| 7 | 21 | 35 | 35 | 21 | 7 | 1 | — |\n| 8 | 28 | 56 | 70 | 56 | 28 | 8 | 1 |\n\nFull-cover bets sum every column:\n\n- **Heinz** (6 picks): 15 + 20 + 15 + 6 + 1 = **57 lines**\n- **Super Heinz** (7 picks): 21 + 35 + 35 + 21 + 7 + 1 = **120 lines**\n- **Goliath** (8 picks): 28 + 56 + 70 + 56 + 28 + 8 + 1 = **247 lines**\n\nNotice how fast the number grows. One more pick more than doubles the lines. This is the geometric explosion that makes £1-per-line Goliath cost £247 upfront.\n\n## Worked Example: 2\u002F3 System Bet Calculation\n\nNothing teaches this faster than running through a full calculation with real numbers.\n\n### The Setup (3 Premier League Picks)\n\nThree picks for this weekend's Premier League card, £30 total stake on a 2\u002F3 system:\n\n- **A:** Liverpool beats Chelsea @ **2.00**\n- **B:** Man City beats Brighton @ **1.50**\n- **C:** Arsenal beats Spurs @ **1.70**\n\nThe 2\u002F3 system means: we need at least 2 of 3 to win for any payout.\n\n### Generating the 3 Betting Lines\n\nC(3, 2) = 3. So there are 3 pairs:\n\n| Line | Pair | Combined Odds |\n|:----:|:-----|:--------------|\n| 1 | A + B | 2.00 × 1.50 = 3.00 |\n| 2 | A + C | 2.00 × 1.70 = 3.40 |\n| 3 | B + C | 1.50 × 1.70 = 2.55 |\n\n£30 total ÷ 3 lines = **£10 per line**.\n\n### Calculating Each Line's Payout\n\nIf every leg won, max payout would be:\n\n$$\\text{Max} = £10 \\times (3.00 + 3.40 + 2.55) = £10 \\times 8.95 = £89.50$$\n\nThat's the best case — all three picks hit, all three pairs settle, all three lines pay. Let's see what happens when only two of three win.\n\n### What Happens with 2 of 3 Correct\n\nSaturday: Liverpool wins (A ✓), Man City wins (B ✓), Arsenal loses to Spurs (C ✗).\n\n- Line 1 (A + B): both winners → pays out\n- Line 2 (A + C): C lost → loses\n- Line 3 (B + C): C lost → loses\n\nOnly Line 1 pays:\n\n$$\\text{Payout} = £10 \\times 2.00 \\times 1.50 = £30$$\n\nYou staked £30 total. You got £30 back. **Break-even**, despite 2 of 3 picks being correct. This is the hidden trap of system bets — partial wins don't always profit. You need either more hits or higher per-leg odds for the math to turn green. (If you want to understand when partial wins fall short at a deeper level, [our beginner's guide on system bets](\u002Fblog\u002Fwhat-is-a-system-bet-explained) unpacks the trade-off from the strategy side.)\n\n## Calculating Bigger Systems: 3\u002F5 and Yankee\n\nNow that the 2\u002F3 mechanic is clear, the same method scales up. The only thing that changes is the number of lines and the amount of arithmetic.\n\n### How to Calculate a 3\u002F5 System Bet\n\nA 3\u002F5 system = 5 picks, at least 3 correct, C(5, 3) = **10 lines**. Each line is a treble (3 legs). Your stake splits 10 ways.\n\nSay you stake £100 on 5 picks all at odds 2.00. Stake per line = £10. Each treble's combined odds = 2.00³ = 8.00.\n\n- If all 5 win: every treble pays. There are 10 trebles, each at £10 × 8.00 = £80. Total = 10 × £80 = **£800**.\n- If 4 of 5 win (say E loses): any treble containing E loses. C(4, 3) = 4 winning trebles. Losing trebles = 10 − 4 = 6. Payout = 4 × £80 = **£320**.\n- If 3 of 5 win (say D and E lose): winning trebles = C(3, 3) = 1. Payout = £80. You staked £100 — still in the red.\n\nThis is why mixing odds matters more than number of picks. With 2.00 odds across the board, even 4 out of 5 correct only triples your money. Lower per-leg odds make partial wins even worse.\n\n### How to Calculate a Yankee (11 Lines)\n\nYankee = full cover on 4 picks. Structure:\n\n- 6 doubles (C(4, 2))\n- 4 trebles (C(4, 3))\n- 1 four-fold (C(4, 4))\n- Total: **11 lines**\n\nEach line is essentially a mini-parlay — if you've ever worked through [how parlay odds multiply](\u002Fbetting\u002Fparlay-calculator), you already know the payout mechanic for one line. A Yankee is just 11 of them stacked together. Stake is per line, not total. A £1 Yankee costs £11.\n\nCalculating a Yankee by hand is tedious but doable. Say you pick 4 events all at 2.00. Structure:\n\n- All 4 win: 6 × (£1 × 4.00) + 4 × (£1 × 8.00) + 1 × (£1 × 16.00) = £24 + £32 + £16 = **£72**\n- 3 of 4 win: the winning doubles are C(3, 2) = 3, the winning trebles are C(3, 3) = 1, four-fold loses. Payout = 3 × £4 + 1 × £8 = £12 + £8 = **£20**\n- 2 of 4 win: winning doubles = C(2, 2) = 1, no trebles win, no four-fold. Payout = £4\n\nAn £11 Yankee with 2 of 4 winners returns £4. Net loss: £7. This is why Yankee bets reward high odds — at low odds, you need 3+ of 4 just to break even. [The Yankee calculator](\u002Fbetting\u002Fyankee-calculator) lays this out line by line for any odds combination.\n\n### How to Calculate a Lucky 15 (15 Lines)\n\nLucky 15 = Yankee + 4 singles. Structure:\n\n- 4 singles (C(4, 1))\n- 6 doubles\n- 4 trebles\n- 1 four-fold\n- Total: **15 lines**\n\nThe 4 extra singles are the big advantage — even one pick winning guarantees some return. Most bookmakers also offer Lucky 15 bonuses: 3× odds if only one pick wins, 10–20% bonus if all four hit.\n\nWith £1 per line, a Lucky 15 costs £15 upfront. One winner at 2.00 returns £2 (plus any \"all-loser consolation\" if the book offers it). All four winning at 2.00 returns £2×4 + £4×6 + £8×4 + £16 = £8 + £24 + £32 + £16 = **£80** — plus any bonus if applicable. [The Lucky 15 calculator](\u002Fbetting\u002Flucky15-calculator) handles the bonus math automatically, which is worth using because every bookmaker configures the bonuses differently.\n\n## The Math Behind Partial Wins\n\nWhy do partial wins often underperform expectations? The intuition: every losing leg kills multiple lines, not just one.\n\n### Why Partial Wins Don't Always Profit\n\nIn a 3\u002F5 system, every losing pick kills C(4, 2) = 6 of the 10 lines (every combination that included that pick). Lose just one pick, and 6 of your 10 lines are dead. Lose two, and 9 of your 10 lines die (only the one treble of the 3 remaining picks survives). The geometry is brutal.\n\nFor full-cover systems like Yankee and Heinz, one losing pick kills proportionally fewer lines (because many lines don't contain it). That's the structural reason full-cover bets feel more forgiving — they distribute the pain.\n\n### The Break-Even Odds Threshold\n\nFor a k\u002Fn system where every pick has identical odds *o*, and exactly k of n win, you break even when:\n\n$$o^k \\times C(k, k) \\geq \\text{total stake}$$\n\nWhich simplifies to: per-line odds raised to k ≥ C(n, k). For a 3\u002F5 system: 2.00³ = 8 ≥ 10? No — you're short. You need per-leg odds of roughly 2.16 or higher for 3 of 5 wins at equal odds to break even.\n\nIn practice, odds vary per leg, so this is a back-of-napkin check. The real calculation is the payout sum from Step 4. But the threshold is worth knowing: if your picks are all at shortish odds (1.50–1.80), partial wins usually don't cover costs.\n\n## Common Mistakes When Calculating System Bets\n\nThree errors account for 90% of confused calculations. Watch for each.\n\n### Confusing Per-Line Stake With Total Stake\n\nA £1 stake per line on a Yankee (11 lines) = £11 total. On a Heinz (57 lines) = £57 total. Bookmakers default to per-line entry on many slips, so the number you type isn't the number that leaves your account. Always confirm the total on the slip before placing.\n\n### Forgetting to Multiply by Stake Per Line\n\nA common beginner error: adding combined odds (e.g., 2.00 + 3.00 + 2.55 = 7.55) and assuming that's the payout. It's not — it's the per-pound multiplier. The actual payout is *stake per line × sum of winning combined odds*. Forgetting this step means you'll massively over-estimate the payout.\n\n### Miscounting Combinations\n\nC(5, 3) ≠ 5 × 3. C(5, 3) = 10. The combinations formula is not intuitive at first — writing 5! \u002F (3! × 2!) looks intimidating if you haven't seen factorials since school. Keep the cheat-sheet table from earlier in this guide nearby, or drop the numbers into [our universal system bet tool](\u002Fbetting\u002Fsystem-bet-calculator) — it shows the line count for every format before you enter odds.\n\n## Interactive Combinations Calculator\n\nInstead of memorizing the table, play with the numbers directly. Enter the total picks and minimum correct, and this tool shows the combinations formula expansion, the line count, and the total stake for any per-line amount.\n\n::inline-combinations-visualizer\n::\n\nThis is pure combinations math — exactly what the bookmaker does in the background when you tap \"system\" on your slip. Once you've seen the factorials cancel out a few times, it stops feeling like algebra and starts feeling like counting.\n\nIf the combinations formula still feels abstract, the mechanics post [how does system betting work](\u002Fblog\u002Fhow-does-system-betting-work) strips the process back to plain-English flow — useful before you commit real money to a 7-bet Trixie.\n\n## FAQ",[27,30,33,36,39,42,45,48,51,54,57,60],{"answer":28,"question":29},"Four steps.
