Criteria Behind the Top 10 Slot Games with Bonus Features

There are plenty of bonus rounds slots available on the Internet, but only a few have made the cut to be featured on our list here. The reality of the situation is that not all bonus casino games offer the same level of entertainment or rewards, with some clearly being better than others. We hold high standards for all aspects of online gambling, and this is also true for bonus round slots. It is not enough to simply have a free spins round or a gamble feature in order to stand out.

Before we even consider the special feature of a game, we need to be sure that it offers the opportunity to win real money. Therefore, playing slots with high payouts is preferable. Furthermore, the best bonus rounds on offer have to be exciting and enjoyable. Last but not least, we want to make sure that any game found on this list is also compatible with the majority of promotions available at online casinos. These are our main criteria, and we will touch on each one below.

The Best Bonus Rounds for 2021

As we mentioned above, one of the factors we consider when judging slots with bonus rounds is the overall quality of the special feature. There are several different kinds of mini-games available online, and you have probably run into some of them already.

These include treasure chests, the gamble feature, pick and choose games, or something completely unique. Triggered either by a number of bonus symbols or specific winning combinations, these features have something great to offer you. Below, we have listed the top bonus rounds you can trigger on video slots:

🍷 Quest for the Grail Avalon II
🎸 Bonus Wheel Guns ‘N Roses
💎 Quest for the Crystal Helm Hot as Hades
🏞 Dinosaur Bonus Game Jurassic Park
🔥 Jackpot Game Mega Moolah
💰 Jackpot Bonus Game Mega Fortune
🦇 Vampire Hidden Treasure Blood Suckers II
👆 Pick & Click Wild Wild West
🥇 The Great Hall of Spins Thunderstruck II
🎰 Supermeter Mode Mega Joker

You may have noticed that some of these bonus rounds are tied to some of top progressive jackpots online. While these extra bonus features may not be the most impressive in terms of gameplay, the jackpots you stand to win are larger than the winnings from any free spins feature can offer you. Of course, if you are after that immersive gaming experience, the rest of the online slot machine games are more than enough to satisfy your needs.

Payouts of the Top 10 Online Slots with Bonus Features

Our list of the top 10 video slots with bonus games takes into account more than just the base gameplay. Spinning the reels is fun and exciting, but is it worth it if the odds are bad?
