What happens between pressing spin and seeing the reels
The journey of a single round, followed by what a day flight lets you do and what an account adds.
Each result is settled before take-off
Pressing spin sends three things to our server: which island you are on, your play amount and a one-off request number. The server makes sure your balance covers the spin, draws the outcome from a cryptographic random number generator and writes the round and your updated balance away in one step. Only after that does the result travel back to be animated.
Why your browser cannot steer a result
Reel strips, symbol weightings and the deciding code all stay on the server. Your screen receives a finished result and draws it; it has no say in what that result is.
Day flights
A day flight lets you try three islands for up to two hours with 80,000 temporary Play Credits. Before take-off you tick to say you are at least 18, live in the UK and agree to the terms. A single cookie links your spins to the flight and is cleared when it lands. Credits from a day flight can never be transferred to an account.
Free accounts for regular flyers
With an account, all thirty islands open up and one balance follows you to every island and device. You also gain favourites, a record of past rounds, the free top-up and the reminder and break settings. Your email address is confirmed before you can spin for the first time.
Play amounts and the top-up
Spins cost 10, 20, 40, 80, 160 or 320 Play Credits, on every island alike. An account whose balance has dipped under 800 may claim a top-up back to 20,000, with three hours between claims. No other source of credits exists.
