Big bass slots, and the two clocks a feature round puts in one game

1

A mechanic rather than a name, and nothing named below

Four words in a search box are what bring most readers to a note of this sort, and big bass slots is a phrase reaching for a construction rather than for a company. Nothing gets named below: not a release, not a studio, not a cashier, not an individual game. What gets priced instead is the mechanic the phrase is pointing at, because the mechanic is what owns the clock and the clock is what nobody prints.

One construction covers the family: a long base game punctuated by a much longer feature round, with the feature collecting symbols and applying a multiplier to what it has collected. Base play is cheap in seconds and thin in return. A feature is expensive in seconds and fat in return. Both are true of the same build at the same moment, and the rest of this note comes out of that.

Three assumptions carry the arithmetic below and each is this note’s own, stated here so a reader can replace it and redo the sums. A feature arrives about once in 150 presses. A feature takes a modelled sixty seconds from trigger to credit. Forty per cent of a build’s total return comes back through the feature and the remaining sixty through base play.

None of those three is published by any source this site treats as authoritative. No regulator prints a trigger frequency, a feature duration or a split of return between modes, and nothing in the offer terms for a pile of spins prints them either. Choosing them openly and showing the working is the only honest way to price a construction of this shape, and every table below is linear in whichever figure it varies.

Eleven pounds fifty-two is the balance everything is worked against, that being the residue 120 presses of 10p expect to leave on a build handing back ninety-six pence per pound staked. Forty times that balance asks £460.80 across the reels, and a 10p stake divides that sum into 4,608 presses. Where both figures come from is set out in detail at slots free spins, and repeating it would crowd out the mechanic this page exists for.

Nothing here was observed, and that sentence carries more weight in this note than in most of them. A duration attached to a feature sounds measured in a way a wagering multiple never does. Every second below is computed from the three figures in the table and from the two the site declares, and a reader who thinks a feature runs for ninety seconds rather than sixty should scale the feature column by half as much again.

Two clocks in one game, and an average that hides both

Twelve point four seconds is the average length of a press on the assumptions above, and no press on this build ever takes 12.4 seconds. Two durations occur. A base press takes the twelve seconds this site models, and a press that triggers takes those twelve plus a modelled sixty, which is seventy-two. The average is a figure describing neither event.

Two hundred and ninety presses an hour is that average restated, against the 300 an hour this site works from elsewhere. Ten presses an hour is the whole visible effect, which is why the average is such a poor instrument here. What it conceals is that 0.67 per cent of presses take six times as long as the rest and pay something like sixty times as much.

Fifty-seven point six pence in the pound is the figure in the last row that deserves a reader’s attention, and it is the base game taken on its own. Sixty per cent of a ninety-six per cent return, spread across every press, leaves the long mode paying back a little over half of what crosses it. A build advertised at ninety-six per cent is a fifty-seven pence build for 96.1 per cent of the time somebody spends on it.

Five pounds seventy-six is the other half of the same statement, being the average payment a feature makes on these assumptions, which is 57.6 times a 10p stake. The symmetry of those two numbers is a coincidence of the forty per cent split and nothing deeper. What is not a coincidence is their relationship: the thinner the long mode, the fatter the rare one, and the two are tied by subtraction.

Nought point six seven per cent of presses are features, 31 out of 4,608, and that fraction is the whole reason an average misleads here. An average is a good summary of a quantity that clusters. Where a quantity has two modes and one of them is reached once in 150 attempts, the average describes the long run and says nothing about any evening inside it.

Thirty-one minutes of feature laid over fifteen hours of base

Fifteen hours twenty-one minutes thirty-six seconds is the base clock, being 4,608 presses at the twelve seconds this site models, which is 55,296 seconds. Thirty point seven two is 4,608 divided by 150, so about 31 features arrive across the condition. Thirty-one minutes is 31 features at the modelled sixty seconds apiece.

Fifteen hours fifty-two minutes thirty-six seconds is the two added together, which is 57,156 modelled seconds. Forty-four sittings of twenty-two minutes is that total converted into the unit this note counts in, with a part sitting rounded up. Forty-two sittings is what the base clock alone would have come to, so the feature costs two sittings and not one.

Thirty-one minutes separates the top row of that table from the bottom, 16 h 8 min 36 s against 15 h 37 min 36 s, which is three per cent of the condition and nothing worth arguing about. Rarity barely touches the clock. What it does to the last column is a tripling, £3.84 against £11.52, and what it does in part five is larger still.

Three per cent is therefore the right answer to the question most readers would ask first, which is how much a feature round lengthens a clearing run. It lengthens it by about half an hour in sixteen. A reader who priced this condition from the base clock alone would be two sittings out across a fortnight of evenings, and no more than that.

31 minutes of feature inside 15 h 52 min 36 s of condition

Two sittings is nonetheless a real cost, and it arrives in an unusual shape. The feature does not spread itself evenly through the run. It lands 31 times, a minute at a go, and those minutes are the only ones in the whole condition during which a reader is not pressing anything at all. Part seven returns to what that does to the pace arithmetic.

4

Where forty per cent of the return actually sits

Eighteen pounds forty-three is what a condition of this length hands the house, being four pence off each pound of £460.80, while the balance standing behind it comes to £11.52. Level pegging between the two needs £288.00 of turnover, twenty-five fours making one hundred, and forty times stands 1.6 times past that meeting point.

Six pounds ninety-one is the distance, and it is the expected position when a condition of this shape closes. Nothing about a feature round alters it. A multiplier concentrates where the money comes back and changes nothing whatever about how much of it does.

Four hundred and forty-two pounds thirty-seven is the total expected to come back across £460.80 of staking at ninety-six pence in the pound. Two hundred and sixty-five pounds forty-two of that arrives through base play, spread over 4,577 presses in dribbles. One hundred and seventy-six pounds ninety-five arrives in 31 payments averaging £5.76, and arrives in 31 minutes.

Twelve to one is the concentration that describes, 40 per cent of the money inside 3.3 per cent of the clock, counting the feature rounds alone rather than the presses that start them. Nothing else on this site compresses value like that. A reader is paying for fifteen and a half hours of pressing in order to be present for half an hour of it.

Thirty-one risers is what the picture shows, and their height is the argument. A reader on the shallow line alone recovers £265.42 of £460.80 staked, which is a loss of £195.38 before the risers are counted. Adding them brings the recovery to £442.37 and the loss to £18.43. Everything standing between those two outcomes happens 31 times in fifteen and a half hours.

Thirty minutes is the average gap between risers at the modelled interval, 150 presses at twelve seconds, and it is a figure worth holding beside this site’s sitting of twenty-two minutes. One expected feature per thirty minutes against a sitting of twenty-two means the modal sitting contains no feature at all, and part six puts a probability on that.

Two hundred and seventy-two presses, and a one in six

Two hundred and seventy-two is the number of presses a balance of £11.52 funds when the feature never arrives, and it is the figure this whole note turns on. Base play returning 57.6p in the pound takes 4.24p out of every 10p press. Dividing £11.52 by 4.24p gives 271.7, and a part press rounds upward as everything does here.

Fifty-four minutes twenty-four seconds is what 272 presses occupy at the modelled interval, which is three sittings. Three sittings is the whole life of the balance for a reader whose feature does not land, against the 44 sittings a condition of forty times asks for. Five point nine per cent of the distance is as far as that reader gets.

Sixteen point two per cent is the chance of exactly that, on a trigger rate of one in 150 and the split assumed here. The working is one line: the chance of missing on a single press is 149 over 150, and 272 presses of missing is that fraction raised to the 272nd power. About one reader in 6.2 therefore watches the balance go without ever seeing the thing the build is built around.

Two hundred and seventy-two stands unchanged down the third column, and the reason is worth a sentence. Holding the feature’s share of the return at forty per cent fixes what base play gives back, so the balance travels the same distance whatever the trigger rate is. Rarity does not shorten the money. It only lengthens the wait, and the last two columns are what the lengthening costs.

Forty point three per cent is the bottom row, at one feature in 300 presses, and two readers in five never reach one. Six point five per cent is the top row at one in a hundred. Six times the risk of a blank run therefore sits between two trigger rates that no document anywhere publishes and that a reader cannot tell apart by looking.

Twenty-eight point eight pence in the pound is the foot of the second column, where seven tenths of the return hides in the feature, and a base game at that rate takes 7.12p out of every press. One hundred and sixty-two presses is all a balance of £11.52 survives there, which is 32 min 24 s and two sittings. One reader in three finishes those two sittings having seen nothing.

Three point six per cent against 33.8 per cent is the span of the last column, a factor of nine between a mildly concentrated build and a heavily concentrated one. Both would be described in the same four words in a search box. Neither publishes the split anywhere a reader could find it, which makes the span a property of the market rather than a choice anybody gets to make.

What rarity does to an evening rather than to an average

One hundred and six presses is a sitting on this build, 1,320 seconds divided by the 12.4-second average, against 110 on a build with no feature at all. Four presses a sitting is what the feature costs in throughput, which over 44 sittings is 176 presses. That is the dullest consequence of the mechanic and the only one an average pace captures.

Forty-nine point two per cent is the interesting one, being the chance that a single sitting of 106 presses contains no feature at all. Roughly every other sitting on this build is a sitting in which nothing happens, in the sense that the mode carrying forty per cent of the money is never entered. The reader still stakes £10.60 in it.

Twenty-four point two per cent is the two-sitting row, and it is where the arithmetic of part five and the arithmetic of this part meet. Two dry sittings cost a reader £8.99 of a £11.52 balance, which is 78 per cent of it, in forty-four minutes. A quarter of all readers are in that position after two sittings, and nothing has gone wrong for any of them.

Two point nine per cent is the five-sitting row, which looks reassuringly small until it is read the right way round. Five sittings is 530 presses, and 530 presses is nearly twice what a balance of £11.52 funds without a feature. A reader cannot actually reach the five-sitting row on this balance, because the money runs out at 272 presses in the third.

Three sittings is therefore the real horizon, and 11.9 per cent is the chance of sitting through all three without a trigger. Part five sharpens that to 16.2 per cent by stopping at press 272, where the money ends, rather than at the close of a third sitting. Both say the same thing in different units: a blank run on a build of this construction is routine rather than freakish.

Nought is the amount by which any of this changes what is expected. Concentration moves outcomes around without moving their average, which is why part four found minus £6.91 whatever the feature does. What concentration changes is how many readers get nothing at all and how few get a great deal, and a long condition is settled by exactly that distinction.

Seventy-two seconds in a cycle, and no rule broken by it

Seventy-two seconds is what one triggering press occupies, twelve of base and a modelled sixty of feature, and that is 28.8 times the shortest gap a licensed slot is allowed to leave between one game cycle and the next. Nothing in that ratio is a breach. The rule sets a minimum and never a maximum, so a long cycle is as compliant as a short one.

Twelve seconds, the interval this site models for a base press, sits 4.8 times above the same floor, so an ordinary press on this build has four fifths of its length available to be shortened before any limit is reached. A feature press has 69.5 seconds of that slack. Neither mode is anywhere near the boundary, which is the point: the boundary binds machine speed rather than build design.

Three hours forty-three minutes is what the whole condition would run if every one of the 4,608 presses took the shortest permitted gap and the feature kept its modelled minute, being 11,520 seconds of pressing plus 1,860 of feature. Thirty-one minutes is unchanged in that total, because a floor on cycle starts says nothing about how long a cycle lasts.

Thirteen point nine per cent is what the feature’s share of the clock becomes in that compressed version, against 3.3 per cent at the interval modelled here. Speeding up the base game does not dilute the feature. It concentrates the clock into it, and a build where the long mode is cheap in seconds is a build where the rare mode owns proportionally more of the evening.

Thirty-one minutes stands unmoved down the third column of that table, and that invariance is the most useful thing in this part. Feature time is a property of the build’s own animation and of how often the trigger lands, and it is untouched by how briskly a thumb works between triggers. Everything else in the table is at the mercy of an assumption.

Nineteen hours fifty minutes twenty-four seconds separates the first row from the last, 3 h 43 min against 23 h 33 min 24 s, on one balance and one multiple. Thirty-eight times the half hour that the whole trigger-rate table moved in part three is what that span amounts to. A reader cannot tell from a lobby tile which row they stand in: the feature plays out visibly in front of them, and the base interval, which decides thirty-eight times as much, is printed nowhere.

Three duties drafted with a feature round in mind

Three requirements in the British rulebook were drafted with a bonus round plainly in view, and none of the three travels. Where an arrangement of this construction is run, no Great Britain licence is behind it, which is an unusual shape of loss: on most notes here a general duty goes missing, and these three name the very mode carrying forty per cent of the money.

Potential prizes and payouts, or else the means by which they get calculated or determined, have to be easily available to a customer before anything is committed. Means of calculation is the operative phrase on a build like this, because the multiplier and the collecting rule are the calculation, and £176.95 of the £442.37 expected back comes through them. Absent that duty the schedule is published only if somebody feels like publishing it.

Freezing is the second of the three. Odds, rules and payouts hold still once play has begun, with the guidance treating as unacceptable any clause that lets an operator rewrite the rules at will. Its one named exception is a bonus round the customer has been properly told about. Licensed treatment of a feature is therefore permissive and conditional at once: it may move the state of play, provided the customer was told what it does.

Shortening the wait for a result is forbidden to a licensed build, with a turbo, a quick spin and a slam stop all named in the guidance, and the same guidance carves out bonus and feature games where no further stake is being wagered. One mode is therefore allowed to be hurried, and it is the mode holding most of the money. That carve-out exists because the regulator was looking at this construction when the rule was drafted.

Three hours fifty-eight minutes twenty-four seconds is what the fourth row of that table would buy, ten times £11.52 being £115.20, which is 1,152 presses and about eight features. Eleven sittings is that in this site’s unit, against 44 at forty times. Thirty-three sittings of somebody’s fortnight is the worth of one line in one code provision, and no line anywhere offshore does the same job.

Two obligations is the entirety of what the offshore rulebook opened for this network has to say about incentives: that the terms be clear and put plainly to the customer, and that promotion not be pitched so hard it drives excessive play. Neither touches a game’s own mechanics. A trigger rate, a multiplier schedule and a split of return between modes are all outside anything that document asks for.

Thirty-one events in forty-four sittings is what a dispute on this build would be about, and that rarity is what makes the complaint route matter more here than on a page about ordinary presses. A reader who believes a feature paid wrongly is disputing one occurrence out of thirty-one, with the record of it held entirely by the other party.

Three things a final decision must carry under a British licence are worth setting out for that reason. It has to explain the decision reached. It has to say in terms that the operator’s own process has now ended. And it has to set out the route onward to an adjudicating body independent of the operator. Away from the register a letter saying the feature behaved correctly is simply where the matter stops.

Eight bodies stand on the approved list the regulator here publishes, and a licensee may use only a body from it, which is the part that does the work. Coverage across sectors is not uniform on that list, so which body is reachable depends on what is being complained about. An unlicensed cashier picks its own adjudicator, writes the terms of the referral, or offers neither.

Four things to establish before the first press

Four questions come out of the parts above, and none of them is about luck or about picking well between arrangements. Each asks which of the two clocks in this construction is going to decide the evening, and the answer is nearly always the rare one.

First, the information panel. Whatever a build publishes about how its feature is triggered and how the collected symbols turn into a payment is the only document that addresses the mode holding most of the money. Reading it costs a few minutes against the 44 sittings a forty times condition asks for, which is the best exchange rate available anywhere on this page.

Second, the base rate. Fifty-seven point six pence in the pound is what base play gives back on the forty per cent split assumed here, and 28.8p is what it gives back at seventy per cent. A reader who can establish roughly how much of a build’s return lives in its feature has established how long their balance survives without one, which is the only number that decides whether they ever see it.

Third, the arithmetic of the dry run. Two hundred and seventy-two presses, 54 min 24 s and three sittings is the life of a £11.52 balance with no feature, and 16.2 per cent is the chance of exactly that. Those figures do not depend on luck improving or on anything being unfair. They fall straight out of the three assumptions set down in part one.

Fourth, the window. Seven days on a 4,608-press condition is 659 presses a day, which is 2 h 16 min 14 s and seven sittings daily at the pace modelled here. Fourteen days is 330 a day and four sittings. Thirty days is 154 a day and two sittings, and only that last row describes something a person with a job completes.

Fifteen hours fifty-two minutes thirty-six seconds, 44 sittings, 31 minutes of feature and a 16.2 per cent chance of never reaching one is this note in four figures. A reader who keeps only their order keeps most of the value: the condition is long, the feature barely lengthens it, the feature holds most of the money, and a sixth of readers never get to it at all.
