Inside the game

Captured in the studio's own free demo on 11 September 2026. Nothing below is taken from a press release or another site — it is what the game shows when you open it.

The base game — Dark Spiral — The base gameThe base game on its six reels and four rows, drawn in black and white in a horror-manga style: chalk-scratched card symbols, hands, faces, and a red summoning banner standing across the third reel. Bottom left, the red BUY BONUS button; the demo bet is €2 against a play-money balance of €5,000.

Game rules, page 1 — Dark Spiral — Game rules, page 1The opening page of the panel. After the tale of the art-room mirrors, ABOUT THE GAME states a six-reel, four-row Ways game whose maximum win of 10,000× the bet is achievable in all game modes. FEATURES then details the Summoning symbols: sized 1x2, 1x3 or 1x4, each reveals a stack of one paying symbol or of Wilds — 3, 4, 5 or 6 symbols for a 1x2, five to nine for a 1x3, six to twelve for a 1x4.

Game rules, page 2 — Dark Spiral — Game rules, page 2The rest of the mechanic, then the first bonus. A Wild landing directly above or below a Summoning symbol on the same reel expands it by one position; winning Summoning symbols stay on the grid and reveal a new symbol at each cascade until no new win occurs, and they land only on reels 2, 3, 4 and 5. Then comes SHATTERED: 3 FS scatters at once in the base game open 10 free spins with an increased chance of Summoning symbols, where 2 FS award +2 spins and 3 or more award +4.

Game rules, page 3 — Dark Spiral — Game rules, page 3The other two bonuses. TWISTED opens on 4 FS scatters at once and awards 10 free spins: it keeps the SHATTERED mechanics and makes Summoning symbols sticky, staying on the grid throughout the bonus and revealing new stacks every spin. Below it, the hidden TORTURED bonus, opened by 5 FS scatters at once in the base game, also with 10 free spins.

Game rules, page 4 — Dark Spiral — Game rules, page 4The end of the TORTURED description — it keeps the TWISTED mechanics and guarantees 2 Summoning symbols on the first spin — then the paytable, priced at the €2 bet shown along the bottom of the screen. The five card symbols all pay alike: €1.00 for six, €0.80 for five, €0.60 for four, €0.40 for three. The high symbols follow, from €2.00 to €6.00 for six of a kind.

Special symbols — Dark Spiral — Special symbolsThe Wild closes the table at €10.00 for six symbols, at the €2 bet visible on screen. The game then notes that its amounts follow the selected bet level and that its RTP was calculated over 10,000,000,000 simulated rounds, after which SPECIAL SYMBOLS takes one line — the Wild substitutes for every symbol in the paytable — before WAYS TO WIN opens.

Game rules, page 6 — Dark Spiral — Game rules, page 6The ways count and the buy section. The panel gives 331,776 possible ways, formed left to right from the leftmost reel, with a valid and an invalid diagram, and recalls that after every win the winning symbols are removed and new ones drop in until no wins remain. BONUS BUY follows with the buy button and FeatureSpins™, listing a buy return per option: 96.23% for BONUSHUNT FEATURESPINS™, 96.29% for SUMMON THE FEATURESPINS™ — a mode in which FS symbols cannot land —, 96.33% for SHATTERED and 96.3% for TWISTED.

Game rules, page 7 — Dark Spiral — Game rules, page 7The controls-and-limits page: the balance and bet displays, allowed bet levels from €0.10 to €100.00 which feature buys may exceed, starting a round with the SPIN button or the spacebar, and how wins are counted — only the highest win per winning way is paid, with very large amounts possibly shown abbreviated and rounded down. The MAX WIN section begins at the foot of the page.

Game rules, page 8 — Dark Spiral — Game rules, page 8The rest of MAX WIN — once the ceiling is reached the round ends immediately and any remaining free spins are discarded — then the free-spins displays, autoplay and its counter, the advanced settings that set a number of plays, a total session loss limit and a single win limit, Turbo Play, unavailable with some operators, and the start of the keyboard shortcuts.

Game rules, page 9 — Dark Spiral — Game rules, page 9The end of the panel: the rest of the keyboard shortcuts, a reminder of what the bottom bar shows, the History that lists only completed rounds, and the general terms. The footer dates these rules to 13 August 2026 and gives game version 1.0.0.

Buying the feature — Dark Spiral — Buying the featureThe buy menu, opened on a €2 bet adjustable at the top. Four entries: BONUSHUNT FEATURESPINS™ at €6, which makes each spin five times more likely to trigger a bonus game, and SUMMON THE FEATURESPINS™ at €200, which guarantees at least 2 Summoning symbols per spin, are activated rather than bought; SHATTERED at €200 buys the 10 free spins with more Summoning symbols, and TWISTED at €400 the 10 free spins with sticky Summoning symbols, which the menu notes may trigger the TORTURED bonus.
