Orrery Stairwell

A spiral staircase lined with star charts, climbing towards a turning brass orrery. Winning symbols fade, fresh ones roll down the steps, and every extra tumble is worth more.

About this world

Orrery Stairwell

Orrery Stairwell climbs at an even pace, one step after another. Twenty lines carry the stake, and the room is built around chains: whenever a line pays, its symbols fade, the ones above slide down the stairs and newcomers fill the top, each fresh tumble paying at a higher multiplier than the last. Spiral Charms stay where they land and never vanish. Three charms in view unlock ten free spins worth double, with Falling Stars stacking on top inside the round. Four charms award fifteen spins, and five award twenty-five.

Falling Stars. Winning line symbols vanish and the rest drop to fill the gaps; the spin pays x1, tumble one x2, tumble two x3, then x5 for each further tumble.

The honest part

Play coins only

Free virtual coins only. There is no real-money gambling, no real-world value in any win and no in-app purchase. A random number generator settles each result; the previous spin never affects the next.

Measured by running this page's own engine for 5,000,000 spins: coin RTP 93.5%, hit frequency 33.2%, free spins about once in 141 spins, a win of 10x your stake or more about once in 82 spins. Coin figures only — no money is staked or returned.

How to play

Orrery Stairwell in three steps

1

Log in with your library card and choose a stake, which is divided over twenty lines.

2

Spin and follow the chain. Each win clears its symbols and new ones tumble in; successive tumbles are worth x2, x3, then x5.

3

Three Spiral Charms in view unlock ten double-value free spins, and Falling Stars stacks on top.

Who it suits

Players who like a steady climb and the small thrill of watching one win set off the next as symbols tumble down the stairwell.

What to expect

A balanced mix of quiet spins and short chains in the base game. Long chains are less frequent, and they are where the larger moments in this room usually come from.

Questions

About Orrery Stairwell

No. Only symbols on winning lines disappear. Charms hold their place and are counted when the chain finishes.

Yes. Chains happen on paid spins too, and during free spins they combine with the doubling.

No. Every spin is independent, and a quiet run does not make the next chain any more likely.

A candlelit alcove of bubbling bottles and a little copper cauldron. When two hourglasses land on a spin that pays nothing, the last reel is brewed once more.
