One free machine with no account, two more behind a free one, and every rule written down.
Playing needs a free account, and the whole form is four fields: a nickname, an email address, a password and a tick confirming you are 18 or over. There is no card field, no address and no phone number, because there is nothing on this site to pay for. The account exists for two reasons: your coins and progress are still there when you come back, and we can keep the games to adults. You can delete it, and everything in it, with one button on your account page.
You start with 50,000 free coins. The same balance, level and missions follow you through every world. The coins are counters and remain so. Nothing sells them, nothing redeems them, and a win is a higher figure on screen and no more than that.
Nothing in this room is for sale. There is no coin shop, and no page on the site ever asks for a card.
Each machine is five reels wide and three symbols tall. A win lands when matching symbols sit on adjacent reels from the first, along the fixed lines printed in the pay table. Your stake divides equally across them, making every table figure a multiple of one line’s stake. The scatter is the exception and pays on the full amount. Where a line carries two wins, only the higher is paid.
| Feature type | What it does | Worlds |
|---|---|---|
| Doubled free spins | Three scatters open free spins with every win doubled | Amber Plinth |
| Sticky wild respin | A losing spin that shows a wild keeps the wild and respins the rest, free | Rose Fresco |
| Climbing multiplier | The free-spin multiplier rises as the round goes on | Marble Arch |
Each reel is a fixed loop of symbols, unchanging. Every spin takes an independent random stop on each reel from the browser’s own generator. Nothing carries over: the spin before counts for nothing, and your balance and your time at the machine change nothing at all.
Return, hit rate and bonus frequency were measured, not modelled. Each game ran five million spins on the code the site actually serves, and the answers are printed in its pay table. They describe coin play in this room alone.
Marble Reel Room is for adults aged 18 and over. Credits are virtual, hold no monetary value and cannot be purchased, sold, withdrawn or exchanged. Nothing in the room is for sale, no prize of real value exists, and a good run here predicts nothing about gambling for money.
