The boilers open to all, the loft and bridge behind a free locker, and every rule written up on the wall.
Copper Fizz Boilers 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.
Paper Gable Breeze and Canal Arch Lanterns need a free account, and the form has just four boxes: nickname, email address, password and a tick to say you are 18 or over. There is no card box, no address and no phone number, as nothing at the works is for sale. The locker does two jobs: it keeps your coins and progress safe for your return, and it keeps the machines for adults. One button on your account page deletes it and everything inside.
The locker opens with 100,000 free coins, topped up with whatever the boilers paid you on the same device. That one balance, level and set of missions goes with you to every machine. Coins are virtual: nobody can buy, sell, withdraw or exchange them for anything, and no win carries real-world value.
The works has no in-app purchases and no payment page in any room.
All three machines have five reels and three rows. A win counts from the leftmost reel and runs right across neighbouring reels along fixed paylines. Your stake is shared equally between the lines, and paytable figures are multiples of the line bet; the scatter is the exception and pays on the total stake. Each line pays only its biggest win.
| Special round on the works floor | How the round plays out in the vats | Machines with it |
|---|---|---|
| Tumbling reels | Winning symbols burst like bubbles, the others drop, and fresh ones fall in from above. Each further win in the chain pays more: x1 on the spin itself, then x2, x3, and x5 for every tumble after that. | Canal Arch Lanterns |
| Rising multiplier | In free spins the multiplier keeps going up as the round runs, and it never slips back down before the round ends. | Copper Fizz Boilers |
| Respin that holds the wilds in the vat | When a paid spin pays nothing but lands a wild, every wild stays put and the rest of the grid spins once more, free. | Paper Gable Breeze |
| Last-reel respin | If a paid spin pays nothing yet shows two scatters, the fifth reel spins round again, free, looking for the third. | |
| Free spins paid at double rate | The plainest round in the works: three scatters start free spins, and every win inside them pays double. |
Every reel carries a fixed strip of symbols. On each spin your browser’s random number generator picks an independent stopping point on every strip. No spin is swayed by earlier ones, and nothing changes with your balance or how long your shift has run.
Hortensia measures each machine’s return, hit frequency and feature frequency by running the machine’s own code for millions of spins, then prints them in its paytable. They cover coin play in these free games and say 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.
