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.
Each machine is free, runs in the browser and draws on the same coin balance. The boilers are open to all; the loft and the bridge open with a free works locker.
3 machines on the floor · free coins in every one

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.

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.

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.
No machine fits those filters.
The lower the share of paying spins, the wilder the machine: wins come less often but land bigger. Choose to suit your mood.

Hortensia ran the very code behind each machine through 5,000,000 spins and copied the readings in here. They concern free froth-coin play and nothing else, and tell you nothing about any real-money game.
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 Each machine runs on virtual coins with no monetary value, and those coins can never be bought, sold, withdrawn or exchanged.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.

One hopper of coins feeds all three machines. A free works locker unlocks the loft and the bridge as well, and keeps your coins, favourites, level and daily missions safe on the shelf for next time.
