Bonus rounds are the heartbeat of slot games. They take your spins to the next level, offering unique features, bigger payouts, and immersive gameplay. Whether you’re a seasoned jackpot hunter or just starting out, understanding bonus rounds helps you choose games that match your style and maximise your wins.

In this guide, we’ll break down the most common types of bonus rounds—like free spins, re-spins, picking games, and instant wins—and explain what makes them so thrilling. Plus, we’ll show you the best games to play for each type, so you know exactly where to start.

What Are Bonus Rounds in Slots?

Bonus rounds are additional features in online pokies that unlock special opportunities to win, often without costing you extra credits. Triggered during gameplay, these rounds introduce unique mechanics, like free spins, multipliers, or interactive mini-games, offering a fresh twist on the base game.

Designed to elevate your experience, bonus rounds break away from standard reel-spinning by incorporating themed visuals, innovative gameplay, and bigger win potential. They’re not just a fun distraction—they’re a key part of what makes modern slots so rewarding.

How Do Bonus Rounds Work?

Typically, bonus games are activated by landing specific combinations of symbols—like scatters or bonus icons—during the base game. Some games use progress bars or other interactive elements to unlock bonuses over time. Here’s how you can unlock them:

PRO TIP: Before spinning, always check the paytable to understand:

Once activated, bonus rounds often shift the gameplay experience entirely. You might see:

Types of Bonus Rounds

Bonus games vary widely in terms of payout potentialodds of activation, and gameplay complexity. Here’s a detailed look at the most common types, ranked for their likelihood of big wins and who they’re best suited for.

Free Spin Bonus Round

Free spins are the most popular bonus type, offering a fixed number of spins at no cost. These are ideal for players looking for simple gameplay with the potential for decent payouts.

They let you spin the reels multiple times without using your own credits. Triggered by landing scatter symbols, these bonuses often come with added features like multipliers, stacked wilds, or bonus-only reels that increase your chances of hitting big payouts. For example, some games double or even triple winnings during free spins, turning a modest bet into a significant win.

Look for games that allow retriggers (earning additional free spins during the round) or pair free spins with multipliers for maximum value. Slots with high RTPs and free spin rounds tend to offer more consistent rewards.

  • Payout Potential: Medium to High
    Free spins often come with added features like multipliers, expanding wilds, or bonus reels, which significantly boost winning chances. Games like Gonzo’s Quest have multipliers that can grow to 15x during free spins.
  • Activation Odds: High
    Free spins are among the easiest bonus rounds to trigger, often requiring 3 or more scatter symbols.
  • Who It’s For: Players who enjoy straightforward gameplay with moderate volatility.

Bonus Buy Bonus Round

Bonus Buy bonus rounds allow players to bypass traditional gameplay triggers and directly access the game’s feature-packed bonus round by paying a fixed cost. This eliminates the need to wait for scatter symbols or bonus triggers, offering instant access to the slot’s most exciting and potentially lucrative gameplay.

This feature is perfect for players who prefer immediate action and are willing to trade upfront cost for the chance to dive straight into high-payout opportunities. Bonus buys often come with increased RTPs during the purchased round, offering better value than waiting for a natural trigger.

  • Payout Potential: Medium to High
    The potential depends on the bonus round’s mechanics, with features like multipliers, jackpots, or free spins offering payouts that can exceed 5,000x your stake. Games like Fruit Party shine, offering cluster-pays with random multipliers of up to 256x during the bonus.
  • Activation Cost: High
    Bonus buys typically cost 50x to 100x your stake. While expensive, they eliminate the variability of waiting for a natural bonus trigger, making them ideal for players who value time efficiency over gradual progress.
  • Who It’s For: Players who prefer high-risk, immediate-reward gameplay.
    Bonus Buy rounds cater to experienced players who understand slot volatility and want to fast-track their access to high-payout features.

Re-Spin Bonus Round

Re-spins are a variation of free spins, with specific symbols locked in place while the rest of the reels spin again. These bonuses are particularly thrilling as they often build anticipation for larger wins.

Re-spins are especially valuable in games with sticky or expanding wilds, as these features compound your chances of winning. Look for slots where re-spins are tied to progressive jackpots or multipliers for even more potential.

  • Payout Potential: Medium
    While individual wins can be smaller, the ability to stack symbols during re-spins can lead to big payouts, especially in games with sticky wilds or multipliers.
  • Activation Odds: Medium
    Re-spins are less common than free spins and are often tied to triggering symbols, like bonus icons or wilds.
  • Who It’s For: Players who enjoy strategic gameplay and the thrill of chasing big combinations.

Pick-and-Click Bonus Round

Pick-and-click bonuses are interactive features that let you select from a set of options to reveal instant rewards. These prizes can include cash payouts, multipliers, or entry into additional free spins. The outcome is random, but the decision-making aspect adds a layer of player involvement that makes this bonus particularly engaging.

Games with multiple pick rounds or escalating rewards are ideal for players who enjoy strategy. Check the paytable to see the range of potential prizes and look for pick bonuses with guaranteed payouts, even if they’re small.

  • Payout Potential: Medium to High
    The payout depends on what you select. Some games include rare jackpot prizes hidden among the options.
  • Activation Odds: Medium
    These bonuses are triggered less frequently but often reward larger prizes.
  • Who It’s For: Players who enjoy decision-making and interactive features.

Instant Win Bonus Round

The simplest bonus type, instant-win features reward players with a cash prize immediately upon activation. These are perfect for players who value quick rewards.

These are typically triggered by landing a combination of bonus or scatter symbols and result in a cash prize directly added to your balance. While smaller prizes are common, some slots tie instant wins to progressive jackpots, offering life-changing sums.

Instant-win bonuses are best for players who value simplicity and quick results. Look for games with tiered instant-win prizes, where higher bets can unlock larger rewards.

  • Payout Potential: Low to High
    Instant-win bonuses vary widely, ranging from small cash prizes to massive jackpots in progressive slots like Mega Fortune.
  • Activation Odds: High
    Instant-win features are relatively common and easy to trigger.
  • Who It’s For: Players who prefer low-stress gameplay and quick wins.

Spin-the-Wheel Bonus Round

This bonus combines chance and anticipation, requiring you to spin a prize wheel to determine your reward.

You spin a prize wheel, and the segment it lands on determines your reward, which can range from cash payouts to multipliers or entry into additional bonus features. The excitement lies in the unpredictability, as each spin could lead to a jackpot.

Wheels with fewer high-value segments tend to offer better odds for bigger prizes. Look for games where the wheel includes secondary bonuses, such as free spins or jackpot entry.

  • Payout Potential: Medium to High
    The prize wheel can award free spins, multipliers, or even jackpot entries. The biggest payouts are rare but possible.
  • Activation Odds: Medium
    These bonuses aren’t as frequent but tend to offer higher rewards than base game payouts.
  • Who It’s For: Players who enjoy a mix of suspense and variety.

Pathway Games Bonus Round

Pathway bonuses take you through a series of escalating challenges, with each level offering better rewards. The goal is to complete all stages without losing, which typically ends the round and returns you to the base game. Rewards might include multipliers, cash payouts, or jackpot prizes.

Slots with second-chance mechanics—where losing doesn’t automatically end the round—provide a better balance between risk and reward. These games are ideal for players who enjoy more strategic, multi-layered gameplay.

  • Payout Potential: High
    Completing all stages often results in significant payouts or jackpots. Games like Monopoly Megaways feature escalating rewards tied to your progress.
  • Activation Odds: Low to Medium
    These are harder to trigger but deliver big rewards if you complete the path.
  • Who It’s For: Players who enjoy high-risk, high-reward gameplay.

Wilds Bonuses

Though not traditional bonus rounds, wild symbols often play a big role in bonus features. Wilds bonuses focus on enhancing winning combinations. Depending on the game, wild symbols might expand to cover reels, stick in place for multiple spins, or carry multipliers that amplify payouts.

While wilds often appear in the base game, they become more powerful during bonus rounds, frequently interacting with other features like free spins or re-spins.

Look for slots that combine wild bonuses with features like cascading reels or progressive multipliers for the biggest payout potential. Slots with stacked wilds or sticky wilds tend to be more rewarding in the long term.

  • Payout Potential: Medium to High
    Wilds multiply winnings or create additional winning combinations.
  • Activation Odds: High
    Wild bonuses are commonly triggered, making them a consistent feature in many games.
  • Who It’s For: Players who want consistent features that enhance both base and bonus gameplay.
