The boiler open to all, two stations behind a free locker, and every rule printed on the batch card.
Bath Bomb Boiler 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.
Rubber Duck Rinse and Lather Cascade need a free account, and the form asks for four things: a nickname, an email address, a password and a tick to say you are 19 or over. You will see no card field, address or phone number, since the works sells nothing. A locker has two jobs: holding your coins and progress for when you return, and keeping the stations adults-only. One button on your account page deletes it, contents and all.
Every locker begins with 100,000 free coins, topped up by anything Bath Bomb Boiler paid you on the same device. Balance, level and missions stay the same at every station. Coins are virtual: nobody can buy, sell, withdraw or exchange them for anything, and no win has real-world value.
The works has no in-app purchases and no checkout page of any kind.
Each station runs five reels by three rows. Wins pay left to right, from the first reel across adjacent reels on fixed paylines. Your stake is shared equally among the lines; paytable values are multiples of the line bet, with the exception of the scatter, which pays on the total stake. On each line, only the largest win is paid.
| Round at the vat | How it runs | Found at |
|---|---|---|
| Tumbling reels | Winning symbols pop and vanish, those above drop down and new ones fall in from the top. Every extra win in the run pays more: x1 on the original spin, then x2, x3, and x5 on each tumble after that. | Lather Cascade |
| Pressure-gauge multiplier | Inside free spins the multiplier keeps rising as the round continues and never falls back while the round lasts. | Bath Bomb Boiler |
| Wilds stay put, the rest respin | If a paid spin wins nothing yet a wild appears, each wild holds its place and the remainder of the grid spins again, free. | Rubber Duck Rinse |
| Last-reel respin | A paid spin that wins nothing but lands two scatters gets the fifth reel spun one more time, free, in search of a third. | |
| Free bubbles worth double | The most basic round going: three scatters trigger free spins, and every win during them is paid at twice the value. |
A fixed strip of symbols sits on each reel. On every spin, your browser’s random number generator picks an independent random position on each strip. No spin is shaped by an earlier one, and nothing adjusts to your balance or the length of your session.
The return, hit frequency and feature frequency of each station are measured by running its own game code for millions of spins, and they are printed in its paytable. They describe coin play in these free games and nothing else; they say nothing about any real-money game.
Grown-ups of 19 and older only. Coins at the works have no monetary value, and nobody can buy, sell, withdraw or exchange them. The factory has no coin counter and no checkout, hands out no prize worth anything in the real world, and success here does not imply future success at real-money gambling.
