From expanding reels to splitting symbols, there are tons of innovations you can try right now. Below, we listed some impressive online slots with innovative bonus features that you'll most definitely enjoy playing. So, let's waste not a second more and dive into these best slots' bonus features that will mesmerize you.
First, this Yggdrasil video slot combines two exciting mechanics – Megaways™ and Infinity Reels™. The supplier took both features a step further by imposing no upper limits on the number of reels and Megaways™. So, with every spin, new reels can unlock, and more ways to win may activate. As if this wasn’t enough, on any spin with 12 or more active reels, an Infinity Bonus of 888x the stake is awarded. Plus, the slot comes with multipliers, wilds, and free spins. How’s that for innovation?
Next on our list of best slots with bonus games is Platooners by ELK Studios. This pokie offers three types of randomly triggered Platooners' action spins. Each of these bonus features grants different benefits. Yet, that's not the unique thing in the game. Instead, there's the amazing Snakes of Fortune bonus game, in which your Platooners should defeat the Snake to earn generous prizes. Depending on how many symbols trigger the feature, you'll get 1-3 Platooners who will attack the Snake. They can be upgraded, get ammunition or bombs, and unlock new levels. Obviously, all of this comes with better payouts and tons of adrenaline, as well.
This article on slot machines with bonus features can't go without Pragmatic Play, one of the most innovative game developers in recent years. The Cash Elevator™ is the pick we chose due to its creative Cash Elevator feature. The game has 12 floors, and you start at the first one. Whenever there's an Arrow symbol, up or down, the elevator moves to the appropriate floor. The higher the floor, the better the symbols. There are also wild symbols and a Dead Lovers free spins feature for extra excitement. That's not all. Cash Elevator™ has the Hold & Spin feature, triggered when the player needs to go to the 13th floor. When activated, the mechanic gets you random multipliers, respins, and lots of cash rewards.
Relax Gaming went all-in with its Book of 99 video slot. The theme of this best bonus slot machine is Greek mythology, and not all symbols are themed. At first sight, there's nothing special here. Yet, the game's RTP is fantastic at 99%, which makes it one of the best picks. Plus, there are some cool bonus features to keep your eye on. First, there's the wild Book of 99 symbol. When it lands, it will move to a tracker on the left side of the screen that increases by the appropriate number of books. When you collect 99 books, it will trigger free spins. You can skip the wait by hitting three wilds, which will instantly trigger ten free spins, as well. These also come with a special expanding symbol that pays on every line, regardless of whether the symbols are connected left to right. Pretty cool!
Reactoonz by Play'n GO is one of the best slot bonus games and a huge hit, thanks to its creative features. Reactoonz 2 just takes the innovation further with all kinds of awesome mechanics. First, there's the Fluctometer that creates Electric Wilds when fully charged. Then, there's the Quantumeter that releases Energoons and Gargantoons. These are both special wilds with their own unique features. Plus, the game has cascading symbols and cluster pays. All its symbols are themed, as well. So, playing it is a real adventure.
Rotten by Hacksaw Gaming is a new release with a solid RTP of 96.27% and 35 paylines. Besides excellent graphics and cool gameplay, the reason we're listing it here is the SwitchSpins feature. SwitchSpins are respins during which random symbols are replaced with top-paying ones. With SwitchSpins, you can expect to get from one to ten respins and reels packed with high-paying icons. This is a truly entertaining game that promises exciting rounds and a new bonus feature.
