Fire Portals is a seven-by-seven cluster slot: connected wins create portal wilds, and those wilds can survive across free spins. Read the RTP in the rules of the version you open.

Which Fire Portals rules does this page cover?
Pragmatic Play introduced Fire Portals in March 2024. Its field of symbols behaves differently from a conventional line slot: the important unit is a connected group, rather than a route stretching across a prescribed set of reels. That difference determines which positions belong to a win.
The official product description and launch announcement establish the grid, cluster threshold and broad portal behaviour. They do not establish which configuration a particular account will open. Keep the name and provider together when comparing a displayed rules panel with another description.
| Published point | Provider description |
|---|---|
| Studio | Pragmatic Play |
| Grid | 7×7 |
| Winning group | Five or more matching symbols joined horizontally or vertically |
| Feature trigger | Three or more scatters |
| Maximum win | 10,000× the bet, in the launch announcement |

Read Fire Portals at the provider · Follow the feature explanation
Start with one cluster, not the whole picture
Five matching symbols can form a group through horizontal and vertical connections. A diagonal resemblance is not the same connection rule. Follow the highlighted positions when a result is shown; visually similar symbols elsewhere on the field do not automatically belong to the paid group.
After a qualifying win, the tumble removes paid symbols and fills the vacancies. Further combinations may then form within that same sequence. Counting every tumble as a separately purchased spin would confuse the original instruction with the changes that follow it.
Watch the paid positions first, then the gaps they leave, then the completed replacement field. That order makes the tumble easier to follow, especially when several effects overlap. The animation may be busy, but the next evaluation still concerns the symbols now occupying the grid.
Why a portal changes the next evaluation
The provider describes a portal wild being placed within the area of a qualifying combination that did not already contain one. It substitutes for ordinary symbols, but not the scatter. When a portal contributes to another win, its multiplier grows and its position changes.
That means a portal is more than decoration left behind by a tumble. Its new location may matter when the following arrangement is evaluated. A larger displayed multiplier still needs the relevant winning event; the number is not a credit already added to the balance.
When several portals share a combination, check their interaction in the opened rules before calculating the result. The merged value on screen belongs with that paid group. Values remembered from earlier frames, or a formula from another portal-themed game, may describe a different situation.
A portal merely adjacent to a paid group is not necessarily participating in it. The highlighted combination establishes that relationship. This distinction also helps when two similar-looking arrangements produce different animations: compare the actual group membership before attributing the difference to a hidden change in the game or its return.
An example of a base-game sequence
Consider an illustrative arrangement containing five connected potion symbols and no portal inside that group. The symbols are paid and removed. A portal is introduced in the group’s area, while replacement symbols complete the field. This describes a possible sequence, not an observed or promised result.
Suppose the replacement arrangement produces another connected win that includes the portal. Its contribution is evaluated, the multiplier increases as described by the provider, and the portal moves. If the next arrangement has no qualifying combination, the tumble sequence finishes; the presence of a portal does not force another win.
The paytable supplies the potion values, and the result display supplies the multiplier and total for a completed round. In this example, the important change is the portal joining a later group. There is no need to assign it a fictional cash award to understand that change.
Free spins change what persists
Three or more scatters activate the free-spin feature. Pragmatic Play describes an award beginning at ten free spins, with larger scatter counts receiving more. Portal wilds persist during the feature, including eligible wilds from the spin that triggered it.
Persistence changes the starting state of later free spins. The next field can inherit portals from an earlier result, rather than beginning with no portal history. Read the remaining-spin counter separately from the symbols: a persistent wild is a retained position, not an extra spin award.
Retained portals make later feature fields different from a fresh base-game field. They may help a new connection, but the replacement symbols still determine whether a group qualifies. A feature can finish with portals on screen; their presence alone does not guarantee a further contribution to its total.
Follow the field, the portal and the counter separately
A simple record can make a complicated animation easier to follow. Note the stage, the active portal values and the event just completed. This is a way to read the feature, not a system for selecting stakes or predicting the next symbol drop.
| Stage | Useful thing to observe | Keep separate |
|---|---|---|
| Initial field | Connected paid positions | Other matching-looking symbols |
| Tumble | Removed symbols and replacements | A new paid spin |
| Portal participation | Wild position and displayed value | An amount already received |
| Free-spin transition | Retained portals and remaining spins | A new guarantee of a win |
What Fire Portals slot RTP can and cannot answer
A published return percentage concerns the long-run model of a specified configuration. It does not describe the chance that a portal appears on the next spin. It also does not guarantee a return from a deposit or make a displayed maximum a likely outcome.
Use the information panel for the percentage attached to the version in front of you. The separate RTP explanation shows why total stakes and a starting balance are different quantities. A portal count cannot be used to calculate either quantity by itself.
High volatility describes uncertainty, not a timetable
The launch announcement classifies Fire Portals as high volatility. That classification concerns the pattern and spread of results under the model. It is not a promise that an uneventful stretch will end with a large feature, or that a feature is owed after a particular number of spins.
Before any paid play, the amount exposed should remain an amount the reader can afford to lose. Increasing it because a multiplier looks impressive changes the money at risk. It does not change what the volatility description actually establishes.
Read a demonstration as a rules example
A demonstration can show the relationship between a disappearing cluster and a retained portal. It cannot establish a personal expected return from a small sample. If the demonstration uses a different configuration, its displayed numbers should not be silently transferred into another version.
Pause after a cluster disappears and again after the replacement field settles. Compare the portal position in both frames and check whether the next highlighted group includes it. Even a sequence with no large result can show these changes clearly; a dramatic win is not needed to demonstrate the rules.
Similar games: compare the rule that changes
For a changing field without this portal system, compare Cloud Quest. Bonanza Billion counts matching symbols through a Pays Anywhere system, while Power of Thor Megaways changes the number of ways. Hot to Burn Extreme provides a fixed-line contrast.
The slot notebook keeps the named releases together. Compare one rule at a time: the qualifying group, the removal process or the state retained between stages. Similar colours and themes are weaker guides than the way a result is actually evaluated.
How can an irregular group still satisfy the connection rule?
Fire Portals does not ask a winning group to resemble a straight row. An illustrative group can bend around a corner or branch from a central position, provided the matching symbols remain connected through the directions stated in the rules. The connection path is the important observation; visual neatness is not another condition.
Picture a short branch of matching symbols. Starting at one end, you can reach the other members by moving through matching horizontal or vertical neighbours. A bend in that path is allowed. This describes how to inspect a completed arrangement; it is not an action that changes the symbols or the outcome.
A similar-looking picture separated by a non-matching position should not simply be joined to that group in the explanation. It may belong to a different connected component, or may not qualify at all. The fact that the same symbol appears elsewhere in the seven-by-seven field does not erase the gap between the positions.
Diagonal contact needs particular care in a small crop. Two symbols can touch visually at their corners while failing the stated horizontal-or-vertical connection. Enlarge the relevant field if necessary and follow the highlighted group. A graphic effect between corners should not be treated as evidence that the game's adjacency rule has changed.
When a portal substitutes in the cluster, count it within the group the game highlights. Matching pictures nearby may still be disconnected from that group. The wild helps form an eligible combination under the rules, but it does not turn every surrounding position into part of the same win.
A modest cluster can make this easier to see than a screen full of effects. Look for a branch with a clear beginning, a bend and an end, then compare it with the highlighted positions. Its value is irrelevant to this check: the question is whether the positions connect under the stated rule.
Why did this portal move while another stayed in place?
A portal can remain visible without contributing to the win currently being paid. To understand a change, first locate the highlighted cluster and check whether the portal belongs to it. A portal elsewhere on the field is still present, but that does not make it part of this particular combination.
In an illustrative comparison, consider one evaluated group that includes a portal and another group elsewhere on the same field. The description should name which group used the wild. Treating the portal as a global modifier for every visible symbol would skip the membership condition that explains why its displayed state changes after participation.
Pragmatic Play links the increase and movement to participation in a win. Compare the group before it disappears with the portal position afterwards. A screenshot taken only after the move shows the new position, but cannot reveal which preceding symbols used the wild if that earlier arrangement is missing.
Several portals can also be involved in a shared qualifying group. Read the combined state actually displayed when that event resolves. It is unhelpful to retain each former portal value as though every earlier separate value necessarily remained independently active after the interaction. The before-and-after state tells a clearer story than a list of all values ever seen.
For the same reason, keep the portal symbol separate from an ordinary paying symbol whose picture disappears. The tumble changes the arrangement, while the portal rules govern the relevant wild state. Group membership, removal and retained state are related steps, but they are not three interchangeable descriptions of one animation.
For a confusing transition, compare the portal value before the win with the value and location after it. Keep the highlighted group beside those frames if it is available. These details explain a change far more clearly than a large multiplier cropped from the rest of the field, with no indication of what preceded it.
Read the replacement field before carrying a connection forward
When winning symbols leave Fire Portals, the new arrangement needs a new connection check. A group that qualified before the tumble does not stay qualified merely because similar pictures remain on the screen. Falling symbols can break a previous visual shape or create a different connected group after the vacancies have been filled.
Consider a schematic group that is removed near a portal. The replacements might bring matching symbols alongside the portal, or might leave it beside unrelated pictures. The retained wild state and the replacement arrangement must be considered together. Persistence describes what remains available; it does not prescribe the symbols that will complete the next field.
After the replacement settles, inspect the new connections from the beginning. A newly recognised group starts another tumble within the same sequence. If no group qualifies, the sequence ends. An unused portal can remain visible at that point without anything being missing from the completed result.
The distinction also prevents an inflated cluster count. A symbol removed in an early group and a replacement symbol seen later cannot both be treated as members of one simultaneous field. A long sequence may display many matching pictures over time without any individual evaluation containing that combined quantity.
A recording that skips a replacement may show the portal at the end without showing how it reached that position. You can still identify the final arrangement, but the skipped transition remains unknown. The artwork in the final frame cannot recover the exact sequence of earlier groups or portal movements.
Fast animation can make a replacement difficult to inspect, even though the same connection rule applies. For a disputed detail, use an available completed history or a recording that captures the transition. Paying for further rounds will produce new arrangements rather than reconstructing the one that was missed.
A retained portal is not an extra free spin
Fire Portals free spins can carry portal state into later feature outcomes. The remaining-spin counter records something different: how many feature spins remain available under the displayed allocation. A portal surviving the transition should therefore be described as retained state, rather than being counted as another spin or an extra award of time.
At feature entry, the screen shows the initial allocation. On later outcomes, watch two separate changes: the portal positions and values on the field, and the remaining-spin counter. A portal carried forward belongs to the next starting arrangement. It does not itself increase the number shown on the counter.
A feature can contain a rich portal history even while the counter moves towards its ending point. The persistence rule does not promise that every later outcome will involve those portals, nor that a retained position will necessarily create a qualifying connection. A later field still has to satisfy its own evaluation conditions.
A screenshot taken halfway through the feature may show several portals already in place. It cannot tell you when each first appeared. To trace their history, you need the preceding outcomes as well. Without those frames, a portal visible now should be treated as present, rather than assumed to have just arrived.
The final feature summary collects completed results. If you have also recorded individual contributions along the way, adding the summary to those contributions would count the same money again. Check whether a number belongs to the current outcome or the whole feature before using it in a comparison with the recorded total.
The feature still ends according to its allocation and the loaded rules, even if its final screen contains promising-looking portals. That ending arrangement is not an unpaid balance carried into an unrelated round. There is no need to continue spending because a portal remained when the earlier feature finished.
A short portal sequence, step by step
A useful example can show one qualifying group without a portal, the introduced portal state and a subsequent evaluation that either uses it or does not. That short sequence isolates the feature's logic. Adding an extraordinary total can make the example more dramatic while obscuring the cause of each change on the field.
Take a hypothetical sequence beginning with an ordinary connected group. Once it is removed, a portal appears in the relevant area and replacements fill the field. The next arrangement may include that portal in a win, or may leave it unused. Both continuations help explain the rule without claiming to reproduce a personal test.
Follow the order: identify the first group, watch its replacement, then check the portal against the next highlighted group. Only after that event resolves should you compare its value and location. A multiplier appearing on screen describes portal state; it does not, by itself, say that the same number has been credited as money.
An example that ends without another win can be equally informative. It shows that a portal's presence and the next arrangement's qualification are separate matters. Explanations consisting only of successful continuations can leave readers with the false impression that the portal forces the field to keep paying until some illustrated target is reached.
Avoid supplying fictional probabilities to make the example feel complete. The sequence explains a possible logical order, not how frequently that order occurs. A few observed or imagined transitions cannot establish the chance of a portal appearing, the likelihood of a merger or an affordable number of attempts before the next feature entry.
The sequence is useful if it helps you recognise the next transition you see. It cannot tell you when a favourable arrangement will arrive or which stake will produce it. Those questions require information the example does not contain, even when every connection and portal movement in the illustration is easy to follow.
A portal screenshot and a settlement record answer different questions
The screenshot can help identify the grid, visible portal positions and displayed values. A completed result history may establish which round those images belong to and what was settled. The two records complement one another, but neither should be assumed to contain every detail supplied by the other.
For a question about a portal's membership in a particular group, the complete arrangement and the highlighted evaluation are especially useful. For a question about a missing account credit, the completed round reference and result record are more direct. A cropped large multiplier image is a weak substitute for either task when its context is missing.
If the portal has moved but its former position was not captured, the missing detail concerns the game sequence. If a completed result is recorded but the account credit is absent, the question concerns settlement. Keep those questions separate when contacting support, so the request asks for the record that can actually resolve the gap.
Do not attempt to recreate a disputed sequence with additional spending. A new paid instruction produces another round and another result. It does not reconstruct the earlier missing arrangement or establish what the earlier history should contain. Preserve what is available and use the genuine service's secure support process for account-specific records.
If the issue concerns a withdrawal after a game result has settled, move to the payment records directory. The receiving route, transfer state and payment reference belong to that task. Fire Portals' wild positions cannot show whether a separate payment instruction was released or reached a bank account.
A complete portal sequence can explain the mechanic without establishing anything about a private account. For an account query, the game version, round reference and completed result matter alongside the image. Casino artwork or a similar-looking example cannot show which version a service loaded or whether it credited that particular round.
Compare Fire Portals by connection, movement and retention
The most meaningful comparison starts with the kind of group that qualifies. Fire Portals uses connected positions. Bonanza Billion provides a count-based contrast, where the ordinary matching quantity is the key observation. Similar jewel imagery does not remove that structural difference in how a field is read.
The next comparison concerns what survives a resolved group. A portal's displayed state differs from ordinary pictures that leave during a tumble. In Cloud Quest, the useful reading follows a designated row and the effect of clearing. Both involve changing fields, but the progress being tracked is not interchangeable.
For a positional transformation, compare Power of Thor Megaways. Its hammer affects symbols below it under that game's rules. The shared importance of position does not mean Thor uses Fire Portals' connected cluster threshold, roaming portal state or free-spin retention conditions. The named release remains the correct boundary for each specification.
Compare the task each field sets: connect a group, count matching symbols, clear a designated row or follow a hammer transformation. Falling symbols may appear in several of these games, but the evaluation differs. The comparison helps you read an unfamiliar result; it does not establish which mechanic will return more money in a session.
Keep unsupported local details outside the comparison. The mechanics pages do not establish the GBP stake range or availability of a particular operator's game instance. Adding those fields from unrelated listings would make the table look fuller while weakening the connection between each claim and the source that can establish it.
Use the slot feature library to move between these different rule systems. Here, the focus remains connected wins and changing portal state. The neighbouring pages explain their own transitions, so you can compare what happens on the field without assuming that similar colours, symbols or effects mean identical rules.
Questions that follow
How many symbols make a Fire Portals cluster?
The provider describes at least five matching symbols connected horizontally or vertically.
Do portal wilds remain during free spins?
Yes. The published feature retains portal wilds through the bonus, including eligible portals from the triggering spin.
Is the Fire Portals maximum win a likely session result?
No. A maximum is a ceiling in the published rules, not a probability or expected return.
Can I infer Fire Portals RTP from a few demo spins?
No. Read the opened version’s information panel; a small observed sample does not verify theoretical RTP.
