How it works

How the mine runs

First world open to all. Two more down the line with a free account. Every rule on paper.

Shardrain Grotto, open to all

Shardrain Grotto 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.

Signing the board

The two worlds further down the line need a free account. The form: four fields. A nickname, an email address, a password and a tick to confirm you are 19 or over. No card field, no address, no phone number; there is nothing on this site to pay for. Why an account? Two reasons. Your coins and progress wait for you between visits, and we can keep the games adults-only. One button on your account page deletes the account and everything in it.

One pool of coins

Starting balance: 100,000 free coins, plus whatever you won in the open world on the same device. Balance, level and missions are shared by all three worlds. Coins are virtual. They cannot be bought, sold, withdrawn or exchanged for anything, and no win has real-world value.

Refilling the lamp

  • Free coins down the shaft every four hours.
  • Daily missions that pay coins into the locker.
  • Each level reached pays a reward.
  • Balance under 2,000 coins? Rumbold tops it up free, instantly.

No in-app purchases. No payment page. Anywhere.

Spins and payouts

Five reels, three rows, in every world. Wins pay left to right, from reel one, on adjacent reels along fixed paylines. The stake divides evenly over the lines. Paytable values are multiples of the line bet; the exception is the scatter, paid on the total stake. One line, one win: the highest.

Bonuses

Bonus on the ore lineWhat the round does on the seamWhich stop
Tumbling reelsWinners vanish. Remaining symbols fall. New ones drop in from above. Each extra win in the chain pays a bigger multiple: x1 on the spin itself, then x2, x3, and x5 for every tumble after that.Shardrain Grotto
Multiplier riding the elevator upIn free spins the multiplier goes up as the round runs and never comes down until it ends.Sheavewell Lift
Wild hold respinPaid spin, no win, a wild on show: every wild stays where it is and the rest of the grid respins once, free.
Last-reel respinPaid spin, no win, two scatters: reel five spins again, free, looking for scatter number three.
Doubled pay in free spinsThe simplest bonus on the line: three scatters start free spins, and every win in them pays double.Porchlight Provisions

Random reels, really?

Each reel has a fixed strip of symbols. Each spin picks an independent random stop on each strip, using your browser’s random number generator. Old spins never influence new ones. Nothing reacts to your balance or to how long you have played.

Where Rumbold’s numbers come from

Return, hit frequency, feature frequency: each world’s figures are measured by running the game’s own code for millions of spins, then printed in its paytable. They cover coin play in these free games and nothing else, and say nothing about any real-money game.

Free social casino. No real-money gambling, not one seam of it.
