Why do the published RTP numbers differ?

Keep the two figures attached to the publications that report them. Thunderkick’s catalogue describes the studio’s product, while the operator page gives its own published example. Choosing the higher percentage would hide the difference without explaining it. Neither source, on its own, identifies the configuration running in an account elsewhere.

A decimal-place difference also needs care. The written values 98.6 and 98.50 are not identical after rounding. Neither page establishes which help screen would appear in an account elsewhere, so the actual game information remains the reference for that particular version.

Why do the published RTP numbers differ?

What does the 25-line layout change?

Fixed paylines describe positions that can form a qualifying match. They are different from a Megaways count, where changing reel heights can change the number of possible routes. Here the key reading task is to follow a permitted line through five reels.

An expanding wild changes a reel’s visible coverage. It does not turn every arrangement on the board into a prize. The line still needs to meet the game’s qualifying rules, and a single screen can contain both useful and irrelevant symbols.

How do the ship and compass features fit together?

MrQ’s explanation places the expanding wild on the middle three reels and describes three or more bonus symbols opening free spins. Those are separate functions: a substitution rule affects line evaluation, while a bonus symbol changes the stage of play.

For an illustrative sequence, imagine a wild joining a qualifying line. The expansion is evaluated within that result. A later board containing enough bonus symbols follows the free-spin instructions instead. This example describes the order of checks without assigning a cash return to either event.

Does low volatility mean a safe result?

Thunderkick labels the game Low volatility. That is a classification of its prize variation, not a promise that every session stays close to the published return. Losing rounds remain possible, and a longer session still exposes more total stake to the game.

RTP is a long-run theoretical relationship between stakes and prizes. It is not a probability that one spin wins, a refund percentage or a timetable for recovering a balance. Comparing two catalogued returns cannot identify the next result.

What should be recorded before comparing a session?

Keep the exact title, the stated return in the opened game and the total stake per paid round together. A result written down without its stake does not provide a useful comparison, and a demo balance is not a withdrawable account balance.

If the displayed name differs, resolve that first. A similar sea theme or a mistyped year in a search result is not enough to establish the same product. The title and studio provide a more reliable starting point than a thumbnail alone.

Which guide makes a useful next comparison?

Temple Tumble offers a contrast in variable ways and blocked positions. Wolf Gold uses a different fixed-line feature structure. Comparing those rules explains what changes between games more clearly than ranking their illustrated prizes or treating a return percentage as a personal forecast.

Keep the year and provider in the identity check

The complete title includes 1429 and Uncharted Seas, with Thunderkick as provider. These details identify the subject more reliably than a ship or compass thumbnail. A sea-themed search result can concern another game, and a mistyped year can lead to a different page. Resolve identity before extracting a percentage or a bonus description.

For a hypothetical research note, place the complete title and studio above each quoted fact. The 98.6% provider field and 98.50% operator example then remain visibly attached to this product. If another source omits the provider or changes the name, flag the mismatch before comparing its numbers. A visually similar image is not enough to repair missing identity information or establish that its rules belong to this release.

Follow the permitted lines, not every matching symbol

Twenty-five is the number of permitted paylines, not a count of all matching symbols on screen. It also does not mean that every reel stop pays twenty-five prizes. Start by finding a path shown in the game’s line diagram, then check the symbols along that path. Matching symbols elsewhere may look useful while having no part in that particular line’s result.

A hypothetical sketch can draw five reel columns and trace one abstract path across them. The sketch illustrates what following a path means; it should not be labelled as an actual 1429 line unless the loaded payline diagram establishes it. An unrelated matching symbol elsewhere remains outside that illustrative path. This keeps a geometric explanation distinct from an invented paytable or a claim that every visually pleasing shape qualifies.

A line diagram and an award table supply different inputs

The line diagram identifies where to look. The paytable identifies which symbol combinations and lengths qualify and what values they carry. Neither input can replace the other. A highlighted path without the relevant paytable entry cannot fully reconstruct a prize, while a symbol value without its qualifying arrangement cannot prove that it applies to a particular board.

To check a result, mark the path, write down the symbols along it and find the matching paytable entry. If the stake basis or table value is missing, stop before assigning a cash amount. This method lets you explain what needs checking without inventing a minimum match count, a left-to-right requirement or a payment for a sequence that the available evidence has not established.

Confirm the row count separately from the five reels

The provider evidence confirms five reels. It does not follow that a familiar row count from another five-reel slot belongs here. Reels and visible rows are separate dimensions. A publication should not complete the board specification from a generic slot image, particularly when the saved research leaves that detail unconfirmed.

A teaching diagram can show five columns without committing to an unverified row count. That is enough to explain reel order and locate the middle three reels. A detailed board reconstruction needs the actual game window and its rules panel. Limiting the picture to established details keeps it useful; filling out a familiar rectangular grid from memory would add a specification the research does not confirm.

Locate the Wild’s middle-reel restriction

MrQ’s description places the expanding Wild on reels two, three and four. This is a location boundary in the operator’s published explanation. Keep it attached to the Wild claim rather than saying that the symbol can expand anywhere. Numbering reels from left to right in a private sketch helps identify the middle three without assigning a prize to them.

In a five-column example, outline columns two through four and leave the outer columns separate. The outline shows where the operator’s description places the expanding Wild. It cannot show that a Wild will appear on every spin or that all three middle reels will expand together. Location and occurrence answer different questions, so the illustration should make the restriction clear without turning it into a promise.

Check the Wild’s contribution before explaining its expansion

The saved operator explanation describes the Wild expanding when it contributes to a payline win. That condition is more specific than merely seeing a ship symbol in the window. First identify the relevant qualifying line and the Wild’s contribution, then follow the expansion under the stated rule. Removing the participation condition would broaden the instruction beyond the publication.

A recording may show the Wild before expansion and identify the positions contributing to the win. Keep those details together when explaining the change. If the image crops out the qualifying line, it may still show an expanding Wild while leaving the cause unproven in that particular round. State what is missing, rather than treating every appearance of the symbol as evidence that the same action must follow.

Expansion changes coverage before it explains a final award

An expanding Wild alters which visible positions are occupied by the special symbol under its rules. That coverage change can matter to qualifying lines, but it is not an independent currency award just because the reel graphic grows. The award still needs the relevant combination, paytable value, stake basis and settlement instruction.

Follow the initial symbol, its expanded coverage and the evaluation that follows as stages of one explanation. They are not three separate cash credits. A result breakdown may connect the stages to paying lines, but the animation alone cannot identify every path or value. This matters in a cropped image where the full-reel Wild dominates the view and the smaller line labels are no longer readable.

Ordinary substitution and bonus entry have different purposes

The Wild’s role in a qualifying line is separate from the Compass bonus-symbol condition described by MrQ. One concerns substitution and line evaluation; the other concerns opening a feature. Adding their counts together would not create a meaningful trigger. Identify the symbol category and the rule it belongs to before counting it.

Mark the Wild’s involvement on a line separately from the Compass symbols you count for bonus entry. A nautical theme does not let one symbol fill the other’s role. The Wild image cannot be counted as a Compass without a rule saying so, and an isolated bonus symbol does not automatically carry an ordinary line value. A single board can therefore need both checks, each using its own qualifying instruction.

Three or more bonus symbols identify a trigger threshold

The operator explanation used here describes three or more Compass bonus symbols opening free spins. That threshold identifies the stated entry condition. It does not, by itself, provide a complete mapping from every possible count to a particular opening award. Preserve the trigger while checking the loaded rules for any additional count-specific entitlement.

A hypothetical result with fewer than the stated threshold does not establish this described trigger. A result meeting it makes the free-spin instruction relevant, but the final cash outcome remains unresolved. The distinction between opening a stage and settling its value is important: a triggered feature is a defined game event, while profit or loss across the completed sequence requires the actual stake and credited result.

An upper allowance is not a standard free-spin award

The saved operator publication describes up to fifty free spins. The phrase up to identifies an upper allowance in that description, not a statement that every qualifying trigger starts fifty spins. Do not remove the qualifier or invent a scatter-to-spin table to connect it with the minimum trigger. The exact opening award should be read from the loaded feature instructions.

If the opening counter is visible after a trigger, a caption can record that displayed count. If the recording starts later, say that free spins are in progress and leave the starting count unknown. The published upper allowance cannot fill the gap. This preserves the useful observation without suggesting that the maximum is the normal opening award or that a short clip establishes every possible trigger entitlement.

Compare the two RTP publications at consistent precision

Thunderkick prints 98.6%, while MrQ prints 98.50%. Writing the first as 98.60% for a precision comparison reveals that the values differ by 0.10 percentage points. This is an arithmetic comparison of the written figures, not a verified explanation of the underlying configuration difference. The sources do not identify every build selected elsewhere.

Keep percentage points distinct from pounds and from a relative percentage change. The difference between two model figures cannot be treated as a guaranteed amount returned in one session. Nor does selecting the larger number identify which model is loaded. Preserve the exact source wording, date and configuration context so that a later check can compare the actual information screen with the published examples.

Do not average sources into a configuration that neither reports

Averaging 98.6% and 98.50% would produce a mathematically valid midpoint but an unsupported game specification. Neither publication identifies that midpoint as the model in a loaded installation. The question is which figure applies to the version being viewed, not which arithmetic summary makes the disagreement disappear.

Use two rows for the published figures and keep their source labels. Add a row for the opened game only when its own information panel provides a percentage you can record in context. That layout preserves the difference for investigation. A blended value might be calculated correctly, yet neither publication would gain authority over it merely because their figures supplied the inputs.

Low volatility and high RTP describe different properties

Thunderkick’s Low label concerns prize variation in its classification. The catalogue percentage concerns theoretical return. Neither field makes the other a guarantee of a small personal loss or a stable session path. A game can have losing rounds despite a low-volatility label, and a limited record can differ from the theoretical percentage.

Different session sequences do not, by themselves, show that the model changed. Check the information panel to investigate configuration, and record stakes and settled returns to describe the session. The Low classification supplies neither a recovery schedule nor an expected interval between Compass events. It can remain a useful provider label without becoming a timetable for when a particular balance or feature should return.

Observed return needs total stakes as its denominator

An opening balance is funds available at one point, while total stakes add the amounts committed across paid starting events. If returned funds are used again, total stakes can exceed the opening funds. Dividing prizes by the initial balance would therefore answer a different question from dividing them by the accumulated stakes.

Keep opening funds, each paid stake and each completed return in separate worksheet entries. Where the game accounts for feature activity under its paid start, keep that association visible as well. A return percentage calculated from the worksheet describes that record only. It is not the theoretical RTP, and a short sample cannot settle which of the differing catalogue and operator models applies to an unidentified installation.

Keep demo credits separate from a cashier record

The saved research records a provider demonstration route for this title and preserves qualifications about rendering verification. A successful launch response or matching game identifier is narrower evidence than an observed working game screen. Keep the existing demo status rather than describing unseen feature activity as tested.

If a demonstration visibly exposes the help panel, it can be useful for locating instructions and checking the displayed title. Its credits do not become withdrawable funds or evidence of an operator’s cashier terms. A hypothetical sequence in this article is narrower still: it illustrates the relationship between a rule and its input without claiming a played round. Publication facts, visible observations and illustrations should remain distinguishable in any final account.

Do not assign a maximum from an unlabelled catalogue quantity

The research deliberately leaves the maximum-win unit unconfirmed where a catalogue field does not clearly define it. An isolated numeral with an ambiguous label cannot safely be rewritten as a times-stake cap or a GBP award. Units and scope are part of the fact, not optional wording added after the number.

A reader can still understand the expanding Wild and bonus trigger without a fabricated maximum headline. If a later loaded rule supplies a clear maximum and unit, that specific claim can be updated with its source. Until then, keep the limitation explicit. Do not calculate a cash ceiling from the game’s line count, the number of reels or an unrelated return percentage, because none supplies the missing award-boundary definition.

Compare the mechanism rather than the nautical artwork

Wolf Gold offers another fixed-line structure with distinct giant-symbol and Money Respin features. Temple Tumble offers a contrast through ways evaluation and blocked positions. These comparisons identify different rule inputs. A ship, compass or landscape theme has no role in establishing whether another title uses the same substitution, persistence or trigger instruction.

Before choosing the next guide, name the uncertainty precisely. It might concern a permitted payline, a contributing Wild’s expansion, the Compass entry condition or a configuration-specific percentage. That question points to the relevant evidence. A broad search for the most generous sea-themed game would not answer it and could mix unrelated titles. The guide directory is useful when it helps preserve each game’s separate mechanics and source boundaries.

Name the detail missing from a result record

If a reader cannot explain an award, identify the smallest missing input before making a calculation. The missing item might be the permitted line, the qualifying symbol sequence, the Wild’s contribution, the stake basis or the relevant paytable value. These are different gaps. A general statement that the board looks valuable does not identify which one prevents reconstruction. Naming the gap makes the next check concrete and avoids guessing several pieces at once.

A screenshot of a Wild covering a middle reel may identify the feature while leaving the paying lines out of view. Another image might show the highlighted lines and result but omit the stake. The first leaves the paying components uncertain; the second lacks a basis for comparing money returns. Both can support a useful explanation, provided you keep the observation within what the image actually shows.

The result history, where available, can connect the completed settlement to its initiating event. Retain that event identifier or chronological association. Do not use a Wild image from one round to explain an award from another merely because both display the same ship. Matching the record is a necessary part of reconstruction, separate from understanding the general feature. It prevents an accurate rule description from being attached to the wrong observed inputs.

Write an enquiry that preserves the applicable source scope

A configuration enquiry can state that Thunderkick lists 98.6% while the dated MrQ publication lists 98.50%, then ask which percentage the opened information panel displays. A mechanics enquiry can ask whether the observed Wild contributed to the highlighted payline before expanding. These questions identify the relevant evidence directly. They do not require selecting an operator, opening an account or placing another paid round merely to understand the rule.

Keep the full title, provider, stage and source context with any answer you record. A row count, maximum-win unit or opening free-spin mapping that remains unverified should stay open. Those gaps do not prevent an explanation of the twenty-five lines, the middle-reel Wild description and the separate bonus condition. The guide is more precise when it identifies what is established than when it tries to fill every possible specification field.

When recording an answer, quote the displayed unit as well as the numeral. A line count, percentage and free-spin allowance can all be copied correctly as numbers yet become misleading if their labels disappear. The label is what connects the observation to the question it actually answers.
