Slots Free Spins: the Spin Clauses, Decoded
A slot's own free spins and a casino's free spins are different contracts in one screen. The decoder reads both clause sets and shows where they meet.
The terms board
Sorted by our editorial score — how clearly each operator publishes wagering, caps, expiry and payout behaviour, and how those rules behave once the arithmetic is run.
Every card carries a score out of 100 and the headline terms the operator publishes. Offers move often — the operator’s own page is always the current truth.

Cards appear in score order. Scores are editorial, terms change often, and nothing here is a recommendation to gamble. Read the operator’s own terms before you claim anything.
The feature clause: a slot's own spins and their contract
Inside every modern slot sits a feature round that awards free spins on its own terms: three or more scatter symbols land, the game awards a stated number of rounds, and those rounds run at the stake that triggered them. The contract is the paytable and nothing else: the feature page states the round count, the modifiers, and what each symbol pays during the round. No wrapper attaches, no conversion ceiling applies, and no clock runs against the result.
That brevity is the point. The provider publishes the feature's arithmetic, the game's return figure already prices it, and no promotion terms can change what a scatter pays or what an expanding symbol covers. Feature spins are part of the game the way the base game is: outcomes on a published distribution, payable into the balance currently in play. When a lobby advertises a slot's own spins, it is advertising mathematics, not a promotion.
Retrigger wording is the line worth finding on the feature page. Many titles allow the feature to retrigger, awarding further rounds from inside the feature itself, commonly capped at a stated maximum at the time of writing; others pay a fixed award instead. The difference moves the feature's value more than its headline multiplier does, because retrigger frequency stretches the round count on the same triggering stake. One glance at the paytable settles which kind of feature you are holding.
The wrapper clause: the casino's spins and their layers
Casinos wrap spins in their own clause set, and the layers stack in a fixed order. The bundle states the count, the named reel and a per-spin value, commonly 10p to 25p at the time of writing. The crediting line states where results go, and the wrapper wording typically reads: your spin results land as bonus funds, and a stated multiple stands between them and withdrawal. Then the ceiling, then the clock. Four layers, each stated somewhere specific, each with a number attached.
Where the bundle needs no deposit at all, the layers tighten: ceilings drop, multiples steepen, and the clock shortens to pay for the access. The no-deposit branch of this wrapper trades value for reachability, and the trade is measurable rather than mysterious: same four layers, harder numbers. A wrapper on a deposit offer and a wrapper on a registration gift are the same contract at two price points, and the layers tell you which price you are being asked to pay.
Behind the layers stands the enforcement question: the spin wrappers on the board above are licensed offshore, not in the UK, so each layer holds only as firmly as the operator's own rulebook under its own regulator. That is the honest frame for everything the layers promise. Read them in order regardless: the crediting noun first, the multiple second, the ceiling third, the clock fourth, because that is the order they bite once a result lands.

The stacking clause: when feature wins meet the cap
When a wrapper spin triggers the game's own feature, the two clause sets stack, and the wording that decides is usually one line: results from spins played with bonus funds follow the bonus. Under that typical phrasing, a feature round triggered on a wrapper spin belongs to the wrapper: its result joins the bonus pool, carries the multiple, and meets the ceiling like any other wrapper result. The feature's own paytable is silent on the matter; the promotion terms are not.
Cash-funded rounds invert the stacking. The same feature triggered on a stake from your withdrawable balance pays into the withdrawable balance: no multiple, no ceiling, no clock, and nothing owed. This asymmetry is the stacking clause in one line: the source of the stake, not the feature itself, decides which contract a result inherits. Two identical feature rounds on the same reel can therefore be worth entirely different amounts, and the terms are the only place the difference is written.
This is the trap most readers walk into: assuming all feature wins are equal because the symbols look equal. They are not, and no visual cue will tell you which contract a round inherited. The page that reads launch-week wrappers clause by clause meets the same trap in a sharper form, because fresh titles ship with both clause sets live at once. The habit is identical either way: identify the stake's source, then read the contract that source carries.
The value clause: pricing both spin kinds
Pricing a feature spin starts from the game's own arithmetic. The feature's expected contribution is already inside the published return figure, so a feature spin is worth its stake's share of that distribution: no task, no tax, no queue between result and balance. At a 20p stake on a reel returning 96 per cent, the long-run value of a feature round is whatever the paytable says it is, and the balance receives it in full. That is the whole pricing case, and it needs no wrapper reading at all.
A wrapper spin prices differently because the wrapper taxes it. Take £1 of spin winnings credited as bonus at a 20x multiple: the task is £20 of turnover, and at a typical 4 per cent house edge the expected cost of clearing is 80p. The clean value of that pound is therefore roughly 20p at typical weights, with the exact share hedged per lobby. The arithmetic scales: steeper multiples push the kept share down, ceilings push the top down, and the face value on the banner stays conveniently fixed.
Per pound of face value, the comparison is now decidable: at the same stake, a feature spin outvalues a wrapper spin by the wrapper's tax, and the gap widens as the multiple steepens. That is the number that decides which spin to prefer when a lobby offers both, and it explains a pattern worth noticing: lobbies advertise wrapper counts loudly and feature rounds not at all, because one is a marketing spend and the other is arithmetic.
Volatility deserves a line here because it changes how the value lands, not what the value is. A high-variance wrapper can sit far below its model for hundreds of rounds and repay the gap in one feature; a low-variance wrapper dribbles toward the model in small steps. The task's expected cost is identical in both cases; the journey differs, and the journey is what the max-bet line and the clock actually govern. Choose the reel for the shape of the trip as much as for the size of the prize.

A worked translation: one session, two spin kinds decoded
Set the session up with both clause sets visible. Deposit £10 and claim 40 wrapper spins at 10p on a named reel, winnings credited as bonus funds at a 20x multiple with a £60 conversion ceiling. The wrapper spins return £3.20, credited as bonus; on spin 22 of the 40 the reel's own feature triggers, and under the stacking wording the £1.40 it pays joins the same bonus pool. The task is now twenty times £4.60, or £92.00 of turnover, all on reels at 100 per cent weighting.
Clear the task at 20p stakes and two more features trigger, both from cash-funded rounds. The first pays £5.60 into the withdrawable balance, no wrapper attached; the second pays £2.30 the same way. The session's two contract lines now read cleanly: £4.60 of bonus results facing a £92.00 task, and £7.90 of feature results already clean. At a 4 per cent house edge the expected cost of clearing is £3.68, so the modelled walk-away from the bonus is 92p against a £60 ceiling never approached.
Exit completes the receipt. The clean line is £7.90; the bonus line contributes its modelled 92p once the task clears; the deposit's own journey is the base game's business, not the offer's. Total modelled value from the offer stack: £8.82 against a headline of forty free spins plus two features, which sounds thin until you remember the features were the game's own mathematics and were never the promotion's to give. Both clause sets paid exactly as their wording said they would.
The eligibility clause: which reels the wrapper allows
Eligibility for wrapper spins is narrower than for most bonuses. The bundle usually locks to a single named reel, sometimes a short list or a provider family at the time of writing, and the named reel is printed in the claim line itself. Staking the wrapper elsewhere typically fails quietly: the spins do not apply, or the session runs on your own balance while the bundle waits. Read the claim line twice, because it carries three clauses in one sentence: count, value and reel.
Both clause sets meet in the stake line. Wrapper spins run at the stated per-spin value regardless of the reel's usual range, and the max-bet line while clearing commonly sits between £2 and £5, breachable in a single oversized round on the wrong reel. The named reel's own minimum stake matters too: a wrapper valued at 10p cannot run on a reel whose floor is 20p, and some terms convert the shortfall rather than refund it. The stake line is where eligibility becomes arithmetic.
Reading the named reel before claiming is the last habit. Volatility shapes the wrapper's results: a high-variance reel produces lumpier wrapper outcomes, a low-variance one produces steadier but smaller figures, and neither moves the expected value; both alter the shape of the journey toward the ceiling or the clock. The paytable, the return figure and the stake range are three facts the lobby will not volunteer together, and the claim line is where they become one decision.
Providers sometimes publish several stake-point variants of the same reel, a 10p build, a 20p build and a 40p build with scaled pays, and lobbies differ over which they stock for wrapper bundles. The variant decides the wrapper's granularity: forty spins at 10p produce a smooth run of small results, while forty spins at 40p produce fewer and lumpier ones from the same claim. Check which build the claim line names before pricing the bundle, because the same spin count can carry two different distributions.
The checklist for comparing spin offers
The comparison scan for any spin offer:
- Name the source: the game's own feature rounds, or a casino wrapper with clauses.
- Write the wrapper's four layers: crediting noun, wagering multiple, ceiling and clock.
- Confirm the named reel, its per-spin value and its volatility before claiming.
- Price the task: winnings times the multiple, at the edge you can measure.
- Check the stacking line: what a wrapper spin inherits when it triggers a feature.
- Find the exit gate: verification and the minimum withdrawal before counting any win.
Rank offers with the value clause and the ranking writes itself. Face value first: count times per-spin value. Task second: expected winnings times the multiple, at the house edge the information panel implies. Kept share third: face value minus the task's expected cost, bounded by the ceiling. A hundred spins at 10p with a 40x multiple loses to sixty spins at the same value with a 20x multiple on most realistic outcomes, and the headline count never says so.
Two contract families, one reading habit: that is what this page leaves you with. The game's own spins need a paytable glance and nothing more; the casino's wrapper needs four numbers, a stacking line and an exit check. When the next offer arrives dressed in either family's clothes, the scan above prices it before the claim button does. The spins were never the offer; the contract around them was, and the contract is now the part you read first.
Frequently asked questions
Are in-game free spins wagered?
No. The game's own feature rounds sit inside the game's published arithmetic: results pay into the balance in play per the paytable, with no wagering multiple, no conversion ceiling and no expiry. That is the standard construction across virtually every lobby at the time of writing, because the feature is part of the game rather than a promotion. Wagering enters only when the casino wraps spins in its own bonus layer, which is a different contract wearing a similar name.
Do feature-spin wins count toward casino caps?
Only when the triggering stake came from the wrapper. Under typical wording, results from spins played with bonus funds follow the bonus: they join the bonus pool, face the multiple and meet the ceiling. Feature rounds triggered from cash-funded stakes pay outside the wrapper entirely. The distinction is invisible on screen and decisive in the terms, so locate the stacking line before claiming rather than after the first feature lands and the difference becomes expensive.
Which spins are more valuable per pound?
The feature spin, at the same stake, on any realistic reading. A feature spin carries no task: its expected value is the game's own return and nothing else. A wrapper spin carries the wrapper's tax: at a 20x multiple and a 4 per cent edge, roughly 80p of each credited pound goes to expected clearing cost, leaving about 20p of clean value. Steeper multiples push that kept share lower, which is why the multiple, not the spin count, decides.
Can feature spins trigger during bonus spins?
Typically, yes: on most reels the scatter mechanic runs regardless of which balance funded the stake, so a wrapper spin can reach the feature like any other. What changes is the contract the result inherits: under the usual wording, a feature triggered by a wrapper spin follows the wrapper, while one triggered by a cash stake pays clean. Read the stacking line in the promotion terms to confirm which construction your lobby actually uses.
Do wrappers lock specific slots?
Commonly, yes. Most wrapper bundles name a single reel in the claim line, and a minority name a short list or a provider family instead. Staking the wrapper on an unnamed reel typically fails quietly, and the spins wait rather than convert. The lock is worth reading before claiming for a second reason too: the named reel's volatility and stake range decide how the wrapper behaves, and neither is negotiable once the bundle has been credited.
What happens to wrapper spins I do not use?
Unused wrapper spins typically lapse at the stated expiry, commonly midnight on the day of credit at the time of writing, with no compensation owed. Credited results are different: once a wrapper spin has paid, its result follows the bonus clock, commonly seven to thirty days. The two clocks are separate clauses, and the shorter one governs the spins. Diary the credit day rather than the claim day, because the clock usually starts whether or not you log in.
