How winnings work (members only)

What 96.5% RTP costs per $100 wagered, the 10,000x max win at a $1 stake

The top prize is capped at 10,000x your stake. On a $1 spin that is $10,000; on $0.20 it is $2,000. When the cap is reached the round usually ends immediately.

Because winning symbols tumble away and are replaced, one paid spin can produce a chain of wins. All of them count towards that spin's total.

What 96.5% RTP means

Expected return = stake × 96.5%
Over $100 of total bets, the long-run average loss is $3.50

RTP is a long-run average across millions of spins. Any single session can finish far above or below it, especially on a medium volatility game.

The published hit frequency is 43.1%, meaning roughly one spin in 2.3 returns something — though many of those wins are smaller than the stake.

Features explained (members only)

3 features explained: free spins, tumbling reels, bonus buy

Free spins

A bonus round of spins played at no cost to your balance, usually triggered by landing three or more scatter symbols. Wins during the round are added to your balance, and many games let you retrigger extra spins.

Tumbling reels

After a win, the winning symbols are removed and new ones fall into their place. This can create several consecutive wins from a single paid spin. Also called cascades or avalanches.

Bonus buy

Lets you pay a fixed multiple of your stake to enter the bonus feature straight away instead of waiting for it to trigger. It raises variance considerably and is not available in every country (it is banned in the UK).

Strategy tips (members only)

Size your stake to the volatility. Medium volatility balances hit rate and win size. Expect dry spells between features, but not extreme swings. A simple rule: bring at least 200 spins' worth of budget, so a $50 budget suggests a stake of about $0.25.

4 more tips and a session planner

Check which RTP version you're playing. Skywind offers this game at 96.5%, 94.5%, 89.5%. Open the game rules at your casino and prefer sites running the 96.5% version.
Treat bonus buys as high-risk. Buying the feature concentrates your budget into a few large-variance rounds. Many results return less than the price paid. Read our bonus buy guide first.
Bonus wagering: at 96.5% RTP, clearing $1,000 of wagering costs about $35.00 on average. Check the bonus terms, as some casinos exclude specific games. Run your numbers in the wagering calculator.
Set limits before you spin. Decide your loss limit and session time in advance and stop when you reach either. No pattern or betting system changes the outcome of a spin.
