Wild Symbols

A wild symbol substitutes for other symbols to help complete winning combinations — similar to a joker in a card game. If you have two matching symbols on a payline and a wild lands in the right position, the wild completes the win.

Wilds come in several variants:

  • Standard wild — substitutes for any symbol except scatter and bonus
  • Expanding wild — expands to cover an entire reel when it lands
  • Sticky wild — stays in place for a set number of spins (common in free spins rounds)
  • Walking wild — moves one position each spin, staying until it falls off the reel
  • Wild multiplier — applies a multiplier to any win it contributes to
  • Stacked wild — appears as a stack of wilds on a reel, potentially covering it entirely

Scatter Symbols

A scatter symbol pays regardless of its position on the reels — it doesn't need to land on a payline to trigger a reward. Landing three or more scatters simultaneously is the most common way to trigger a free spins round.

Scatter payouts are usually expressed as a multiplier of your total bet, not your line bet — which makes landing multiple scatters in a base game spin disproportionately valuable.

Some modern slots use scatter symbols that contribute to a counter or meter rather than triggering directly — filling the meter activates the bonus.

Free Spins

Free spins let you spin the reels without using your balance. They're triggered most commonly by landing scatter symbols, and they almost always come with enhanced mechanics — expanded wilds, multipliers, or additional scatter opportunities — making them the highest-value part of the game.

Some games offer retriggerable free spins — you can land more scatters during the free spins round and add extra spins to your total. In high-volatility games, a large retrigger sequence is often where the biggest wins occur.

Multipliers

A multiplier increases the value of a win by a set factor. A 3× multiplier turns a $10 win into $30. Multipliers appear in several forms:

  • Win multiplier — applied to a specific win when it lands
  • Free spins multiplier — a global multiplier applied to all wins during a free spins round (e.g. all wins pay 3×)
  • Progressive multiplier — increases with each consecutive win or each spin in a bonus round
  • Wild multiplier — a multiplier attached to a wild symbol, applied when the wild contributes to a win

In high-volatility slots, multipliers inside the free spins round are often the mechanism behind the game's biggest potential wins. A 10-spin round with a 10× multiplier on each win produces dramatically different results than the same round without one.

Bonus Rounds

A bonus round is a separate game mode triggered by landing bonus symbols (or sometimes by scatters, depending on the game design). Bonus rounds vary significantly between titles:

  • Pick-and-click — you choose from a grid of hidden prizes; common in retro-style games
  • Wheel spin — a prize wheel awards a multiplier, free spins or instant cash
  • Trail bonus — you advance along a path, collecting prizes at each stop
  • Second-screen game — a separate mini-game opens with its own mechanic

Bonus rounds are often where the most significant wins occur, which is why triggering them is a central goal of most pokie sessions.

Cascading Reels (Avalanche / Tumble)

In a cascading reels game (also called Avalanche or Tumble depending on the developer), winning symbols are removed from the grid and new symbols fall in to replace them. If the new symbols form another win, those also cascade away — and this continues until no new wins form.

Cascades are frequently combined with progressive multipliers — each cascade in a sequence increases the multiplier, meaning a long chain of wins can result in a very large payout from a single spin.

Games using this mechanic include Pragmatic Play's Gates of Olympus and NetEnt's Gonzo's Quest.

Megaways

Megaways is a game mechanic licensed from Big Time Gaming that uses variable reel heights to change the number of ways to win on every spin. Each reel can show 2–7 symbols, with the combination creating up to 117,649 ways to win simultaneously.

Because Megaways games don't use fixed paylines — any matching symbols in consecutive reels from left to right form a win — they feel quite different from traditional slots. They're typically high-volatility games with large maximum wins and extended dry spells between significant payouts.

Buy Feature (Bonus Buy)

The buy feature (or bonus buy) lets you pay a fixed multiple of your current stake to enter the free spins round or bonus game directly — skipping the base game trigger entirely. The cost typically ranges from 50× to 200× your stake depending on the game.

This feature gives players direct access to the highest-value part of the game without waiting for the scatter trigger to land. However, the feature is not available in all regions and may be subject to regulatory restrictions.

Important
The buy feature amplifies both the excitement and the risk — you're spending a large multiple of your stake upfront with no guaranteed return. It's a high-variance decision that requires careful bankroll management.

Slot Features FAQ

What's the difference between a wild and a scatter?
A wild substitutes for other symbols to help complete payline wins — it works within the payline structure. A scatter pays regardless of position (no payline needed) and is usually the trigger for free spins. They perform entirely different functions, and most slots include both.
Do multipliers apply to jackpot wins?
It depends on the game. Many slots explicitly exclude jackpot wins from multipliers — the jackpot pays its fixed amount regardless. Others do allow multipliers to apply. Check the specific game's paytable rules.
Are Megaways slots higher volatility?
Generally yes. The high number of ways to win is offset by smaller individual payouts per combination, and the big wins are concentrated in the free spins round. Most Megaways titles are classified as high or very high volatility.
Can I trigger free spins during a free spins round?
On games with retriggerable free spins — yes. Landing the required scatter symbols during your free spins adds more spins to the remaining total. Not all games allow this; check the paytable to see if retriggers are possible.
Is the buy feature worth it?
Mathematically, the buy feature is priced to reflect the value of the bonus round — so it doesn't give you better odds, it just skips the waiting. Whether it's "worth it" is a personal decision based on your bankroll and how you want to play. It's a high-stake, high-variance move.
