Best Online Slots with Bonus Games

Online slots with bonus games add fun features and mini games to keep the gameplay exciting, and also provide you with plenty of chances of winning big.

If you’re looking for online slots with the best bonus games, you can’t go wrong with these top titles:

Pink Panther, Playtech

You may remember Pink Panther as a crime-solving sleuth from kids’ TV. Every episode was an adventure, and that’s what you’ll find in the Pink Panther slot from Playtech. With two progressive jackpots and five bonus games, it’s one of the best online slots with bonus games we’ve come across.

Bonus games and features in Pink Panther include opening safes to win free spins, multipliers, and expanding wilds; taking your pick of prizes in the picking bonus, a wheel of fortune bonus, a trail bonus full of traps and prizes, and a bonus game that includes blowing up symbols on the reels, which then turn into wild symbols.

The Dark Knight Rises, Microgaming


The Dark Knight Rises online slot game by Microgaming will immerse you in action packed gameplay, thanks to the quality graphics, sound effect, many bonus features, and the chance of winning four different levels of progressive jackpots.

Bonus games include a fight between Batman and Bane to win free spins and multipliers, which can be triggered after any winning spin. You’ll also want to trigger the Symbol Scramble bonus game, which scrambles each symbol on the screen and rearranges them in the best possible way to win.

Ghostbusters, IGT

If you’re a fan of the Ghostbusters movie from the 80s you’ll enjoy the online slot from IGT – and not just for its nostalgic theme, but also for its lucrative bonuses. Ghostbusters has four randomly triggered bonus features, which includes shooting ghosts for multipliers and two picking bonus games.

The Psychic Bonus sees you picking a card that matches with the one held up on the screen by Dr. Venkman for a prize, while the Paranormal Pick gives you the chance to win a progressive jackpot – chase Slimer to select one of the five options, which all lead to paranormal progressive bonus rounds.

Family Guy, IGT

Family Guy fans will enjoy the online slot version by IGT for its familiar characters and epic range of bonus games. Select different characters in the Drunken Clam bonus game for the chance of winning up to 1,000 times your bet, and benefit from extra wilds during Lois’s Hot Free Spins bonus.

The World bonus will see Stewie spinning the globe to reveal your prize, and you can watch Peter and the chicken fight to the death in the Chicken Fight bonus, awarding you prizes as they go.

Gonzo's Quest, NetEnt

Gonzo's Quest is one of the more innovative titles NetEnt has created in recent years and is also one of its most popular. It has cascading Aztec symbols instead of traditional reels, and this innovation carries onto its Free Fall bonus round that triggers an avalanche of multipliers.

How rewarding the bonus round is depends on how many wins you're able to line up successively. You can get up to a 15x multiplier if you manage to get a few wins in a row, but one miss during your round will reset your cumulative multiplier.

What are Bonus Games?

Bonus games or features are mini games within online slots, commonly triggered by hitting a selection of symbols (typically three scatter symbols, or a pair or more of other symbols), and bonuses can also be triggered at random.

The different types of bonus games and features in slot machines are:

  • Free spins - you'll receive a number of free spins at your current stake where you keep any winnings and can’t lose any money during the bonus.
  • Re-spins - you'll be rewarded an extra spin at your current stake for free, often with symbols held in place.
  • Pick-me – also, called a picking bonus, this enables you to play an interactive mini-game and win instant prizes by picking from random themed selections.
  • Instant win - receive an instant cash prize.
  • Added/extra wilds - new or extra wild symbols may be added to the reels to help you form more winning combinations.
  • Pathway game - progress through a series of mini-games and win bigger prizes as you go along. It can often be part of a progressive jackpot game.
What makes a good bonus game?

Because bonus game slots are some of the most popular in the gaming world, the best online casinos will offer a diverse selection of slot machines with bonus games – often hundreds!

So, how do you sort the good from the bad? The three most important factors to look out for are:

  • Hit frequency - an online slot game could have the best bonus game in the world, but if you can only play it once every 50,000 spins it isn't very accessible! The best online slots have bonus games that are triggered frequently.
  • Payout potential - a bonus slot game may come up often, but it might only double your prize. The best online slot bonus games and features will multiply your bet by a considerable amount.
  • Fun factor - besides the money, one big reason that online slot machines have bonus games is to make the game more fun. If a bonus game or feature isn’t exciting or fun to play, it might as well not have one. A boring game is a bad game, after all!

Are Bonus Game Slots Better than Regular Slots?

Some online slots don't have any bonus games at all. This is often the case for classic slots, which emulate one-armed bandits and keep things simple and stripped-down. For other slot games that don’t have bonus games and features, it can be because they offer a high chance of winning without a bonus.

At OnlineSlots.com, we think bonus games add to the excitement of playing slots, and often bonus rounds offer the chance of hitting the jackpot. With all that considered, it’s no surprise that many of the world's most popular online slots feature one or more bonus games or bonus features.
