Copper Fizz Boilers
Round copper boilers spill pastel bath bombs and pink steam curls from their brass valves. Anyone can pull the lever straight away, and the free round builds pressure the longer it runs.
On the works' lantern evening the canal footbridge is dressed in vermilion paper, carp streamers flying and a gilded crane landing on the span. A bold world of tumbling reels, and every win that follows another in the same spin is boosted.
The machines cost nothing and always will. Your locker holds the 100,000 coins, favourites, level and daily missions between shifts — and lets us check you are 18 or over before your first spin.
Virtual coins only: no real-money gambling, no prizes of real-world value and no in-app purchases. 18+.
Canal Arch Lanterns is the liveliest night in Netherfold, when the wrappers carry their brightest paper out to the bridge over the works canal. Much of the value sits with the Gold-Rim Drum and the Gilt Crane, so the arch can stay dim for a while before the lanterns blaze. Each paying line is unfolded off the reels, the paper above slips down and new folds flutter in from the top, and every further link in the chain is worth more: once, twice, three times, then five times. Arch Lanterns stay hung and are never cleared. Hang three anywhere and the bridge grants ten doubled free spins, chain boost and all; a fourth lantern on the rail brings fifteen, a fifth brings twenty-five.
Tumbling Folds. Paying symbols unfold off the reels and new paper drops in behind them; the opening win in a chain pays x1, the next pays x2, the one after x3, and each win beyond that x5, and on top of that every free-spin win is doubled.
Every machine runs on free virtual coins. Nothing here is real-money gambling, no win has real-world value and there are no in-app purchases. A random number generator decides each result, and no spin is influenced by the one before.
Measured by running this page's own engine for 10,000,000 spins: coin RTP 92.6%, hit frequency 33.0%, free spins about once in 139 spins, a win of 10x your stake or more about once in 82 spins. Coin figures only — no money is staked or returned.
Sign in, step out of the works gate to the canal and set a stake for the lantern-lit arch.
Spin. Paying symbols unfold away and fresh ones flutter down; the opening win of the chain pays as listed, the next double, the third triple and any win beyond that five times over.
Three Arch Lanterns light ten doubled free spins; with four lit the bridge allows fifteen, and with all five twenty-five.
Patient players happy to watch a few dim spells on the bridge in return for the occasional bright run of tumbling wins.
The widest swings in the works. The drum and the crane hold the heavy pays, so wins tend to arrive in bunches with longer quiet spells between them.

The five card ranks (10 to A) pay the least. Three Arch Lanterns anywhere open the free round. Full values for three and four of a kind are in the paytable.
Only the reels set it: the chain carries on for as long as each new fall forms another win, and the fourth link and all those after it pay five times.
Yes. The bridge doubles every win of the free round before the chain boost multiplies it further, and fresh lanterns hung during the round lengthen it.
That is how the arch is built: the rare drum and crane carry the big pays, and no machine here keeps a tally, owes a win or holds one back.
Missions refresh each day, count on every machine and are entirely optional.

Up in the wrapping loft the folders have made a whole paper rooftop from offcuts, pinwheels turning on every chimney. The calmest world in the works, and a paid spin that lands empty gets a free second turn with its stars held.

Lather Vat Works admits adults of 18 and over and nobody else. Each machine runs on virtual coins with no monetary value, and those coins can never be bought, sold, withdrawn or exchanged. You will not find a coin counter or a payment page anywhere in the works, no prize of real-world value is on offer, and doing well here does not imply future success at real-money gambling.
