One wing open to everyone, two more for free members, and each rule recorded in full.
Spiral Stacks is open to everyone: spin it on the home page or on its own page with free play coins. There is no name, email or password to give and nothing to tick.
Owlwork Observatory and Wingcase Cabinet require a free membership, and the visitor book has only four entries: a nickname, an email address, a password and a tick confirming you are 19 or over. It contains no card field, no address and no telephone number, since the hall sells nothing. Membership serves two ends: it holds your coins and progress for your return, and it keeps the exhibits for adults. A single button on your account page deletes the membership with all that it contains.
Members begin with 100,000 free coins, together with any winnings from the open wing on the same device. The one balance, level and set of missions accompanies you into each wing. Coins are virtual; they cannot be bought, sold, withdrawn or exchanged for anything, and winnings have no real-world value.
The hall contains no in-app purchases and no payment page in any wing.
Each wing has five reels and three rows. Wins are read from left to right, beginning on the first reel and continuing over adjacent reels along fixed paylines. The stake is divided evenly among the lines; paytable values are multiples of the line bet, save for the scatter, which pays on the total stake. Only the largest win on any one line is paid.
| Kind of special round | Its effect | Wings |
|---|---|---|
| Tumbling reels | Symbols forming a win are removed, those remaining drop, and new symbols descend from above. Each successive win in the sequence is worth more: x1 on the original spin, then x2, x3, and x5 for every subsequent tumble. | Wingcase Cabinet |
| Ascending multiplier | Throughout the free spins the multiplier ascends, and within that round it never decreases. | Spiral Stacks |
| Wild re-spin, wilds held | Should a paid spin win nothing yet show a wild, all wilds are held in position while the remainder of the grid spins again without charge. | Owlwork Observatory |
| Last-reel respin | Should a paid spin win nothing yet show two scatters, the fifth reel turns once more without charge in search of a third. | |
| Free spins at twice the pay | The most straightforward round in the hall: three scatters award free spins, and each win during them is paid at twice its value. |
A fixed strip of symbols belongs to each reel. On every spin, an independent random position is chosen on each strip by your browser’s random number generator. No spin influences any later one, and nothing adjusts to your balance or the length of your visit.
The return, hit frequency and feature frequency of each wing are measured by running that game’s own code over millions of spins, and are set out in its paytable. They relate only to coin play in these free games and say nothing about any real-money game.
Admission is restricted to adults of 19 years or older. All play uses virtual coins of no monetary value; they are not for sale, cannot be sold on, and can be neither withdrawn nor exchanged. The hall has no coin counter and no payment page, it awards no prizes of real-world value, and success in its galleries does not imply future success at real-money gambling.
