Top Online Slots with Bonus Games (Free and Real Money)

Online, Slots, Bonus, Games, Jewels, Coins, Letters

Let’s face it, slots with bonus games offer a heck of a lot more than the old-school fruit machines many of us grew up playing. While those can still be fun, I prefer free spins, bonus wheels, jackpot rounds, picking games, and other cool slot bonus features!

For players who feel like I do, I created this list of casino slots with bonus rounds (free and for real money). There are games for USA, UK, Canadian, and European players, as well as others from around the world. In each casino, I show you one of the top online casinos for slots that offer it.

Are you ready to play fun slot machines with epic bonus features and potentially win life-changing payouts? Let’s get spinning!


  • RTP: 96%
  • Developer: RTG
  • Jackpot: No

There are endless online slots with Ancient Gods themes. Asgard is based on an old Norse one, and it’s one of the best RTG slots, in my view. It has 243 ways to win, four different free spins rounds, and the Thunderbolt feature can turn a number of reels wild at random.

Let’s focus on the epic free spins round. It’s progressive in nature, so further rounds are unlocked each time you trigger it.

The features are named Goddess, Loki, Thunder God, and Valhalla. They offer 15 spins with 3x multipliers, 20 spins with a wild middle reel, 25 free games with wild multipliers, and 30 spins with morphing symbols, respectively.

You can play this slot at El Royale Casino. There’s a $7,000 welcome bonus for all new players and over 100+ RTG slots. This is one of my top-rated casinos for American players.

Immortal Romance

  • RTP: 96.68%
  • Developer: Microgaming
  • Jackpot: No

This is one of the greatest vampire slots of all time, but it’s also one of the top slot games with bonus rounds. Immortal Romance has 243 ways to win, expanding wild symbols, and up to five reels can turn wild on any spin.

However, the main bonus round to focus on is the free spins feature. It’s called the Chamber of Spins, and there are four of them in all; Amber, Troy, Michael, and Sarah. They have multipliers, vampire bats, rolling reels, and creeping wilds, respectively.

This is truly one of the best slots with bonus games. You can play it and many others at Betway Casino. This UKGC-licensed site has generous welcome and loyalty bonuses and pays quickly when you win. There are literally hundreds of great slots at your disposal.

Raging Rhino

  • RTP: 95.91%
  • Developer: WMS
  • Jackpot: No

This is one of the best free slots with bonus games. It was originally a real money slot machine, but it has been adapted so you can play it at social casinos like Jackpot Party.

Raging Rhino has 4,096 ways to win an epic free spins feature. Why is it so good? You can trigger up to 50 free spins each time it activates, and retriggers are possible, too. 2x and 3x multipliers boost wins throughout. This is one of the best free slots with bonus games if you like free spins.

As I mentioned above, you can play Raging Rhino at Jackpot Party. You’ll get 45 million free coins when you sign up, and there are many top slot games available for free at this social casino site.

Satoshi’s Secret

  • RTP: 96%
  • Developer: Endorphina
  • Jackpot: No

Bitcoin and cryptocurrencies have been all the rage in recent years, and the mystery of Satoshi Nakamoto continues to intrigue people. This slot is based on Bticoin’s anonymous creator. Bonus rounds include a trading feature, a gamble feature, and the QWERTY bonus round.

Both features are different, so they’re worth highlighting. In the trading round, you get a 30x payout and bet on whether Bitcoin will appreciate or depreciate against other currencies for potentially bigger wins. In the QWERTY feature, you try to hack into and raid bank accounts.

You can play this and other casino slots with bonus games at PlayAmo. This casino doesn’t accept American players, so it’s one mostly for Europeans. It offers a $/€ 100 + free spins bonus for all new players and has over 1,000 games.

Take the Bank

  • RTP: 96.10%
  • Developer: Betsoft
  • Jackpot: No

Once in a while, a slot developer comes up with a bonus round or feature that’s truly unique. This bank heist slot has one of them. It also has a free spins round with up to 10 shifting wilds on the reels throughout it.

Tip Box Icon

The unique feature in Take the Bank is the ‘heist spins.’ This game is played in lots of 10 spins; each time you spin, a bomb counter will count down from 10 to 0. All robber symbols convert into bombs and stick on the reels, and after the counter hits zero, they explode and turn into wilds.

This is one of my favorite bonus slot games. You can try it for free at WowVegas. This social casino does not accept real money wagers, and it is just for fun. It’s a great way to test some of the best slots and have fun without any risk.

About Gavin Lucas
Hi! I’m Gavin Lucas, a gambling enthusiast with a particular love for video slots and live casino games. I have been writing about gambling online since 2015, and am always keen to try new games as soon as they’re released. Other than gambling, I’m obsessed with technology and I've written numerous articles for CoinGeek on the topic. I’m fascinated by how online gambling will be changed by blockchain technology, micropayments, and the Metaverse. Having tested several blockchain casinos already, I believe I can see what casinos will look like 10 years from now, and I enjoy sharing that vision with others.
