Superfecta Permutations vs Traditional Fixed-Odds Returns
I once watched a punter at Sandown lose his composure over a winning superfecta. He’d nailed the 1-2-3-4 in a Saturday handicap, picked his payout slip up at the Tote window, and asked the cashier – twice – why no fixed-odds equivalent existed. The cashier shrugged. He’d waited his whole betting life for that result and discovered there was no Computer Straight version of it to compare against.
That awkward gap is the whole subject of this article. The superfecta – the four-position bet, called the First Four on some UK operator menus – has no fixed-odds equivalent the way the forecast has the CSF or the tricast has the CST. There is no Computer Straight Superfecta. The only place in UK racing to back a 1-2-3-4 in correct order is the parimutuel pool. That single fact reshapes everything about how the bet should be approached.
The mechanics and why permutations grow faster than your stake plan
The cost formula extends naturally from the tricast. A box exacta uses n×(n-1) for ordered pairs. A box tricast uses n×(n-1)×(n-2) for ordered triples. A box superfecta uses n×(n-1)×(n-2)×(n-3) for ordered quartets, and the growth is brutal.
Take a £1 unit. Four horses produce 24 permutations and cost £24. Five horses produce 120 lines and cost £120. Six horses produce 360 lines and cost £360. Seven horses produce 840 lines and cost £840. The escalation between five and six selections is where most casual punters underestimate the slip. At seven selections you’re effectively forced to drop your unit stake to 10p, which gets you back to £84 – still real money for a bet that wins less often than once a meeting.
This is also why the dividend on a superfecta, when it lands, can be enormous. The pool absorbs the money of hundreds of punters who all tried to box and got close, all of whom lose. The winning unit collects from a heavy fund. But the cost-of-coverage problem cuts the other way: if you needed seven horses to cover the result, the £840 outlay can swallow the dividend whole.
Where you can actually back a superfecta in the UK
Walk into a betting shop and ask for a superfecta and you might get a blank look from a younger cashier. The product trades under different names depending on the operator. The Tote calls it the Trifecta on three positions and the Quadpot or Placepot on multi-race products – but for a single-race four-position bet, the marketed name on UK Tote is the Trifecta family with an extension, while individual bookmakers sometimes offer their own First Four product.
Most UK punters who want a four-position bet end up on the Tote because that’s where the pool exists. Fixed-odds operators occasionally price their own First Four on big-handicap fixtures with their own formulae, but the dividends are limited and many operators cap the maximum payout, which defeats the purpose of an exotic with rare wins and big collects.
Liquidity is also patchy outside the festival days. On a Cheltenham Saturday in the National Hunt season, the four-position pool is fat enough to support a meaningful dividend. On a quiet Tuesday at Lingfield, the pool can be so thin that even a winning slip pays unexpectedly modest amounts. Field size matters too – Premier Flat fixtures averaged 11.02 runners per race in BHA’s Q3 2025 reporting period and Premier Jumps 9.41, so the natural home for the superfecta is the busier meetings where the four-deep result actually deserves a serious pool.
The race profile where a four-position perm earns its keep
Most superfectas I’ve cashed have come from contested handicaps with 14 or more runners. That isn’t coincidence. The four-position bet wants two things at once: a field broad enough that boxing four horses leaves real upside (you’re not just covering all the obvious shortlist), and a race shape where the favourite is genuinely vulnerable so the dividend reflects a result the public didn’t see coming.
Group 1s rarely qualify. The 5-runner Coronation Cup, the 9-runner Champion Stakes – too short a field, too predictable a top of the market. A 16-runner Cesarewitch with three short-priced contenders and a long tail of 12/1+ horses is the dream setup. The same applies on jumps: the contested handicap chases at Cheltenham and Aintree are where the meaningful four-deep pools live.
The other condition is going. Heavy ground in a long-distance handicap can reshape a result enough that a 25/1 stayer finishes third or fourth, lifting the pool dividend dramatically. Boxing four horses on quick ground in a sharp 5f handicap is a different proposition – the favourites tend to fill the first two slots more often, and the pool dilution from casual money on the favourite line keeps the dividend modest.
Keying instead of boxing – the four-position twist most punters miss
One of the most useful structural tricks on a superfecta is keying – fixing one horse as the certain winner and boxing the remaining three positions among a wider list. The maths drops sharply compared to a full perm.
Suppose you genuinely fancy one horse to win and want to cover four others for second, third and fourth in any order. Instead of a five-horse box at 120 lines, you have one fixed first place and a three-from-four permutation for the remaining positions. That’s 4×3×2 = 24 lines, not 120. A £1 keyed superfecta costs £24 instead of £120, an 80% reduction on outlay for a similar result-coverage.
The trade-off is structural. If your «certain» horse runs second, you lose the whole £24 even though the rest of your shortlist filled three of the remaining slots. The discipline a key forces is brutal – you need to be right about the winner specifically, not just about the contenders. For punters with a strong horse-of-the-week or a stable jockey going at a course they dominate, keying turns the superfecta from a lottery into a more disciplined bet. For everyone else, the open box is the safer architecture.
A keyed approach also pairs well with the race-selection logic I walk through in this guide to picking the right UK race for box bets – both share the same starting point of identifying where the favourite genuinely deserves to be cemented in the result and where it’s vulnerable.
Does the UK have a fixed-odds superfecta?
Not as a standard cross-bookmaker product. The CSF and CST cover forecast and tricast, but no equivalent algorithm exists for the four-position bet. A handful of operators run their own First Four products with bespoke formulas, but the standard route in UK racing is the Tote pool.
How does keying differ from a pure box in a four-position bet?
A pure box covers every possible order of your selections. A key fixes one horse in a specific position – usually first – and permutes the remaining positions among the rest. The result is a sharply lower outlay (24 lines instead of 120 for a five-horse field with one key) at the cost of needing to be right about the keyed position specifically.
