Norrie Crag for anyone, Tanbark Quay and Halflight Pier with a free account, and the rules set out in full below.
Norrie Crag 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.
Tanbark Quay and Halflight Pier need a free account, and the form has just four parts: a nickname, an email address, a password and a tick to say you are 18 or over. You will not be asked for a card, an address or a phone number, because nothing on the isle costs money. The account does two jobs: it keeps your coins and progress for when you return, and it lets us keep the games to adults. One button on your account page deletes it along with everything in it.
You begin with 100,000 free coins, plus whatever Norrie Crag paid you on the same device. One balance, one level and one set of missions run through all three worlds. The coins are virtual: they cannot be bought, sold, withdrawn or exchanged for anything, and nothing you win has real-world value.
Nowhere on the isle will you find in-app purchases or a payment page.
Each world has five reels and three rows. A win counts from the first reel on the left and runs rightwards over neighbouring reels along fixed paylines. Your stake is shared equally between the lines, and paytable values are multiples of the line bet, apart from the scatter, which pays on the whole stake. Each line pays only its biggest win.
| Bonus on the isle | What happens on the croft reels | Isle worlds that have it |
|---|---|---|
| Tumbling reels | When a win lands, its symbols disappear, the others drop down and new ones fall in from above. Each fresh win in the chain is worth more: x1 on the spin itself, then x2, x3, and x5 for every tumble after that. | |
| Climbing multiplier | In free spins the multiplier rises as the round goes on and never falls back before the round ends. | |
| Sticky wild respin | A paid spin that wins nothing but shows a wild holds every wild where it landed and spins the rest of the grid again, free. | Tanbark Quay |
| Last-reel respin | If a paid spin wins nothing but lands two scatters, reel five spins once more for free, looking for the third. | Halflight Pier |
| Doubled free spins | The simplest round on the isle: three scatters start free spins, and every win inside them pays double. | Norrie Crag |
Every reel carries a fixed strip of symbols. On each spin your browser’s random number generator picks an independent random stop on every strip. Earlier spins never sway later ones, and nothing shifts with your balance or with how long you have been playing.
For each world we ran the game’s own code for millions of spins to measure its return, hit frequency and feature frequency, and the results sit in its paytable. They describe coin play in these free games and nothing else, and say nothing about any real-money game.
Only adults of 18 and over may play on Puffinholm Isle. Each game runs on virtual coins with no monetary value, and those coins can never be bought, sold, withdrawn or exchanged. The isle has no coin shop and no payment page on any of its pages, it offers no prizes of real-world value, and doing well here does not imply future success at real-money gambling.
