One ticket equals 60 ordinary stakes. Natural bonuses occurred once per 133 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
17 rules screens from the gameThe Witch, Cat, horned skull, Moth and eye jar begin paying with two matching symbols; the card ranks require three. Only the highest-paying qualifying combination on each line is paid, starting on the leftmost reel. A pair of Witches returns one stake on its line, rising to 500 stakes for five, and the Book can stand in for the ordinary symbols. The default layout uses ten lines across the lower three rows, leaving the upper two visible rows inactive.
Inside the active field, three or more Books unlock the natural feature. For an entry triggered on three rows, keeping those rows grants ten free spins; switching to four or five rows reduces the allowance to eight or six. One symbol type is randomly selected as Golden for the feature, with one optional reshuffle before play begins. Further sets of three active Books add ten spins in the selected three-row mode.
Ordinary line combinations are evaluated before Golden Symbols expand. The expanding award then uses matching reels even when other reels separate them, covering every active row on those qualifying reels. Premium Golden Symbols need two reels and Golden card ranks need three; each eligible line pays the corresponding symbol-table amount. A Golden Jack on three reels therefore pays 0.5 stakes on each of the ten lines, adding five stakes to any ordinary line win.
Shadow Rows changes both the field and the charge: four active rows supply fifteen lines for 1.5 times the base stake, while five rows supply twenty lines for twice the base stake. Separate feature tickets cost 60, 90 or 120 base stakes for three, four or five rows. Every ticket starts with ten spins, and its row count cannot be changed after purchase. The recorded purchase series uses only the 60-stake ticket.
Version 1.3.12 accepts an unboosted stake from EUR 0.10 to EUR 100 and offers Fifty Fifty and Wheel of Bonus choices for wagering a payout. All such offers were collected in this test, and the first Golden Symbol was retained. The declared 96.01% regular and 96.20% three-row purchase RTP figures assume the optimal reshuffle strategy in the rules, including replacing a Golden card rank; the expected RTP of the fixed retain-first policy has not been established.

Verdict
The shorter match paid moreTwo Books followed by a Ten offered competing interpretations on one line in round 307: the Books could complete three Tens for EUR 0.50, or pay EUR 1 as a pair. The game chose the larger amount, showing why counting the longest matching sequence can misread its payout. That was an ordinary spin at EUR 1, with no Golden expansion involved.
The full ordinary series returned EUR 9,815.40 from EUR 10,000 wagered, measuring 98.15% RTP. Its 75 natural features played 780 free spins and supplied EUR 2,748.50 of that return. Golden expansions accounted for EUR 2,345 of the feature money, including EUR 1,261 on 104 spins whose qualifying reels were separated by a gap. The remaining EUR 403.50 came from ordinary line combinations within those free spins.
Every feature kept its first Golden Symbol, so the declared 96.01% regular and 96.20% purchase RTP values, which assume an optimal reshuffle strategy, are not expected returns established for this test policy. The separate fifty-ticket series cost EUR 3,000 and paid EUR 2,553, measuring 85.10%; its median ticket returned EUR 18.30 against a EUR 60 price. Forty tickets fell short of their cost, and purchase 49 alone returned EUR 854.40 with the Golden Moth.
Round 4763 led the ordinary series with EUR 514.50 from a spin that did not trigger free spins. Even the biggest complete natural-feature round was driven by its opening screen: round 4645 returned EUR 156, but only EUR 2 came from the ten free spins. Its initial line awards had already paid the other EUR 154.
- Golden expansions across separated reels contributed EUR 1,261 over 104 natural free spins.
- Three natural retriggers added thirty spins, bringing the feature sample to 780 spins.
- Two ordinary rounds paid EUR 514.50 and EUR 501 without a bonus trigger.
- Empty outcomes accounted for 6,687 ordinary rounds, with another 1,797 paying less than the EUR 1 stake.
- Forty of fifty purchased features failed to recover their EUR 60 ticket price.
- During natural features, 374 of the 780 free spins had no line or Golden payout.

10,000 ordinary rounds, including naturally triggered features, at a fixed EUR 1 bet; 50 bonus buys at EUR 60 each (60x); mode: Three rows and ten paylines; the first Golden Symbol is kept at every natural feature and every three-row purchase. All Gamble offers are collected. No Shadow Row boosters, locked reels or symbol reshuffles; recorded on the official Nolimit City demo server (jurisdiction DEFAULT, RTP profile 96.01%); every request and response logged; test run 2026-10-08. The 50 purchases cost EUR 60 each at a EUR 1 base stake and are reported separately from 10,000 ordinary rounds. Published 96.01% and 96.20% theoretical RTP assume the optimal symbol-reshuffle strategy described in the rules; they are reference values, not the expected RTP of this fixed retain-first policy. Browser media is a separate session excluded from both samples. The shared CSV cascade_steps column records server steps, including feature setup, free spins and collection; this game has no cascades.
The test rig plays the official demo build over the network and records every server round: bet, win, cascade steps, free spins, collect.

FAQ
6 questions · answered from the logCan a pair of Books outrank three matching Tens?
The game pays the highest-valued qualifying combination on each line. In round 307, the two Books at the start of one line were worth 1 stake, matching the two-Witch value, while using both as Wilds before the Ten would have paid only 0.5 stakes. That is a line award, not an anywhere payment for two Scatters.
Are all five visible rows active at the EUR 1 setting?
Only the lower three rows and ten lines are active at the tested EUR 1 ordinary stake; the two shaded rows above are inactive. Activating a fourth row gives fifteen lines for EUR 1.50, and a fifth gives twenty lines for EUR 2. Those Shadow Rows settings were excluded from the recorded statistical series.
Does a EUR 90 ticket start with extra free spins?
All three ticket sizes begin with ten spins: EUR 60 selects three rows, EUR 90 selects four and EUR 120 selects five at a EUR 1 base stake. A purchased ticket fixes the row count. By contrast, a natural trigger on three rows offers ten spins on those rows, eight on four rows or six on five.
Which Golden Symbol choices produced the displayed test results?
The first randomly selected Golden Symbol was retained in all 75 natural features and all 50 purchases, with no reshuffle. The rules tie their 96.01% regular and 96.20% three-row purchase RTP figures to an optimal strategy that replaces Golden card ranks. The expected RTP of the retain-first policy is unknown; the measured 98.15% and 85.10% describe only these two samples.
Is the advertised 30,338x a confirmed payout ceiling?
The provider sheet reports 30,338x as an outcome from a simulation of ten billion rounds. It does not establish an enforced cap, so that figure is not presented as the hard maximum here. The largest ordinary-series round in this test paid 514.50 stakes, while the best purchased feature paid EUR 854.40 on a EUR 1 base stake.
What extended the filmed ticket to twenty spins and EUR 82.30?
Three Books during the fifth free spin added ten to the original ten-spin allowance. With the Golden Jack retained, the completed feature paid EUR 70 from expansions and EUR 12.30 from ordinary line combinations, totalling EUR 82.30 for the EUR 60 ticket. The filmed ticket belongs to a separate browser session and contributes nothing to the 10,000-round or fifty-ticket statistics.
