One seam open to anyone, two more past a free account, and each rule set down in writing.
Amethyst Tramline 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.
A free account opens the other two seams, and the form has only four fields: a nickname, an email address, a password and a tick to say you are 19 or over. There is no card field, no address and no phone number, because nothing on this site is for sale. The account serves two purposes: your coins and progress stay put for your return, and we can keep the games to adults. A single button on your account page deletes it along with everything inside.
Your starting tally is 100,000 free coins, plus whatever you won in the open world on the same device. The same balance, level and missions go with you into every seam. Coins are virtual: nobody can buy, sell, withdraw or exchange them for anything, and no win has real-world value.
You will find no in-app purchases and no payment page in any corner of the site.
Each seam runs five reels by three rows. Wins pay from left to right, beginning on the first reel, across adjacent reels on fixed paylines. Your stake divides evenly between the lines; paytable values are multiples of the line bet, except for the scatter, which pays on the full stake. Only the top win on each line is paid.
| Kind of special | What happens on the face | Seams that have it |
|---|---|---|
| Tumbling reels | Symbols in a win disappear, the rest drop and new ones fall in from the top. Every further win in the chain is worth more: x1 on the spin itself, then x2, x3, and x5 for each tumble from then on. | Glimmerfall Grotto |
| Rising multiplier | In free spins the multiplier keeps rising as the round continues and never goes back down within it. | Amethyst Tramline |
| Wilds set fast in the rock for a respin | A paid spin with no win but a wild on show locks every wild where it is and spins the rest of the grid once more, free. | |
| Last-reel respin | A paid spin with no win but two scatters gives the fifth reel one more free turn, searching for a third. | |
| Free spins where every win counts twice | The plainest round in the mine: three scatters trigger free spins, and each win during them is doubled. | Tarnlight Shallows |
Each reel holds a fixed strip of symbols. On every spin, your browser’s random number generator picks an independent random position on each strip. No spin is influenced by earlier ones, and nothing changes with your balance or the length of your session.
Return, hit frequency and feature frequency for each world are found by running the game’s own code for millions of spins and are shown in its paytable. They apply to coin play in these free games alone and reveal nothing about any real-money game.
Only adults aged 19 or over may play at Gem Hollow Mine. Each game uses virtual coins holding no monetary value; they cannot be bought, sold, withdrawn or exchanged. The site has no coin shop and no payment page in any tunnel, no prize of real-world value is ever offered, and success here does not imply future success at real-money gambling.
