One ticket equals 100 ordinary stakes. Natural bonuses occurred once per 323 ordinary rounds in this sample. Stakes multiplied by this interval measure gross wagering, not the net cost of obtaining a bonus. Purchase returns above include the complete purchased round and are divided by the ticket price.

How it plays
7 rules screens from the game
Fire Portals pays connected blocks on a seven-by-seven board. At least five identical symbols must touch through their horizontal or vertical edges; a diagonal meeting does not join two groups. Winning symbols disappear, replacements occupy the empty cells and any resulting blocks are paid before the round closes. The book is the scatter and does not disappear with an ordinary winning block.
A winning block with no portal creates one in its area after the symbols explode. This wild substitutes for paying symbols and begins at 1x. Its value contributes to any winning block using that position, then increases by one for each winning combination that used it. After the explosion it can move one position within the winning area, staying through the remaining tumbles of that paid spin.
When a block contains several portals, the payout uses their current combined values. The later merger is a separate step: after the win is paid, the updated portal values multiply together to form one wild. Purchase 4 shows this split clearly: 1 plus 322 gave a 323x payout factor, while the updated values of 2 and 323 formed a 646x portal. If competing combinations share wilds, the merger gives priority to the group containing more wilds, then to the higher-paying symbol; no portal can exceed 2,500x.
The books open free spins with three or more scatters. Three, four, five, six and seven award ten, twelve, fourteen, sixteen and eighteen spins respectively. The same scatter counts add those amounts again when they land during the feature. Existing portals from the triggering spin carry into the bonus, where portals remain across spins until the feature finishes.
At USD 2 per ordinary spin, the direct-entry button asks for USD 200, and the bought trigger can land three to seven books, so a longer opening award is possible without a retrigger. Ante raises the ordinary stake and adds bonus symbols to the reels, with purchases then unavailable; both statistical series used the ordinary USD 2 setting with Ante off. Marked as high volatility, this build allows stakes from USD 0.20 up to USD 300 including Ante, with theoretical returns of 96.06% for ordinary play, 96.00% with Ante and 96.01% for purchases. The round stops on reaching its win ceiling, 10,000x at the tested setting, cancelling unused features.

Verdict
The merger pays the next winPurchase 10 finished with a 1,768x portal still on the board. Two clusters had just paid USD 663, bringing the feature total to USD 759.80, before the updated portal values merged. Every subsequent response through the end of the feature paid zero. The largest merged portal in the test therefore contributed nothing after it was created.
Two entries dominated the purchase ledger: number 4 paid USD 1,068.10 and number 10 paid USD 759.80. Only three other purchases covered the USD 200 cost. Against a USD 62.70 median, the smallest payment was USD 6 on purchase 12. None of the fifty features retriggered; longer starts came from their initial scatter awards.
Ordinary play produced the test's largest stake multiple without free spins: round 990 returned USD 731.80, or 365.9x, over twelve steps. The complete 10,000-round sample returned 96.26%, close to its 96.06% setting, within an approximate 95% band of 79.70% to 112.83%. The first natural feature did not arrive until round 377.
The balance eventually finished USD 747.30 below its start, after a peak-to-trough decline of 990.7 stakes. There were 1,364 rounds between the bonuses on 2260 and 3625, despite ordinary clusters paying within that gap. Fire Portals offers an unusually visible multiplier calculation to study; the purchase ledger also shows how little that growing machinery sometimes returned for its entry price.
- The current payout and the later merged multiplier can be checked separately in the saved responses
- The largest ordinary-play round reached 365.9x without waiting for a bonus
- Existing portals carry from the triggering spin into free spins
- Forty-five purchases left part of their USD 200 cost unrecovered
- No purchased feature earned a retrigger in this fifty-entry sample
- A near-profile measured RTP still came with a 990.7-stake drawdown

FAQ
5 questions · answered from the logDo merged portal values change the win already paid?
No. A winning cluster is settled with the portal values that contributed to it. The wilds then grow and merge, creating a factor for later combinations. The rules example above follows both stages of purchase 4; purchase 10 shows the other possibility, where a large new portal remained unused until the feature ended.
Can a portal help more than one symbol group at once?
Yes. Its value applies to each qualifying group that contains it. That also means it can gain more than one increment during a tumble. When shared portals could merge through different groups, the rules first favour the group with more wilds, then the higher-paying symbol; no portal can exceed 2,500x.
Will buying free spins preserve the portals from my previous spin?
No. Portals persist through a paid round and carry into a feature triggered within that round, but an ordinary round that has ended does not leave its portals waiting for a later purchase. A USD 200 purchase has its own trigger and subsequent board.
Does a twelve-spin purchase mean the bonus retriggered?
No. Four books can award 12 spins at the start, while a retrigger requires another qualifying scatter event during the feature. The initial awards were checked on their own; none of these 50 purchases retriggered.
Was the 57.19% purchase return the game's advertised RTP?
No. It was the measured result of spending USD 10,000 on fifty USD 200 entries and receiving USD 5,719. The captured rules set the purchase profile at 96.01%. Fifty results, including a USD 6 low and a USD 1,068.10 high, give a limited sample of that profile.
