Gus's Gold Megaways

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.

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

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.

Ante bet

An optional extra charge on each spin, typically +25%, that increases the chance of triggering the bonus feature.

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).

Fixed jackpots

Jackpot prizes set at fixed multiples of your stake, such as Mini, Minor, Major and Grand.

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.

Hold and win

Landing enough special cash or coin symbols starts a respin feature: those symbols lock in place, the respin counter resets each time a new one lands, and their values are collected when the feature ends.

Megaways

A licensed mechanic where the number of symbols on each reel changes every spin, so the number of ways to win can run into the hundreds of thousands.

Mystery symbols

Special symbols that all reveal the same randomly chosen regular symbol, which can complete several wins at once.

Respins

Selected reels or the whole grid spin again without a new stake, usually triggered by a specific symbol combination or near-miss feature.

Wild symbols

Wilds substitute for regular paying symbols to help complete winning combinations. They do not normally replace scatter or bonus symbols.

• Understand the ante bet. It costs more per spin to trigger features more often; it does not change the game into a better bet.
• Bonus wagering: at 95.97% RTP, clearing $1,000 of wagering costs about $40.30 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.
