Cool Online Slots With Innovative Bonus Features to Try in 2021

Players never seem to get bored by all the amazing online slot machines on the iGaming market. There’s a good reason for that, considering how game providers always come up with creative features to boost the gameplay. 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 bonus mechanics that will mesmerize you.

Odin Infinity Reels Yggdrasil

Odin Infinity Reels™ (Yggdrasil)

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?

Platooners ELK Studios

Platooners (ELK Studios)

Platooners by ELK Studios offers three types of randomly triggered Platooners action spins. Each of these grants different benefits. Yet, that’s not the most 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.

Cash Elevator Pragmatic Play

Cash Elevator™ (Pragmatic Play)

This article can’t go without Pragmatic Play, one of the most innovative game developers in recent years. 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.

Book of 99 Relax Gaming

Book of 99 (Relax Gaming)

Relax Gaming went all-in with its Book of 99 video slot. The theme is Greek mythology, and not all symbols are themed. At first sight, there’s nothing special here. Yet, the game’s RTP is fantastic 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 10 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 2 Play’n GO

Reactoonz 2 (Play’n GO)

Reactoonz by Play’n GO was a huge hit thanks to its creative bonus 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.

Other Top Picks

It’s really impossible to mention all the impressive online slot bonus features and innovations. There are new options every month too. Each one seems to break new grounds in terms of innovations. So, let’s just briefly mention a few picks you may want to try as well.

  • Joker Troupe (Push Gaming) – You can unlock additional rows, spin the Green Joker Wheel with multipliers and coins, and experience the innovative Hypermode™ free spins.
  • Hell’s Kitchen (NetEnt) – See random Ramsay’s Wilds arrive on the reels in the form of knives and pots. Partake in a free spin Team Challenge, pick your team, and hope for it to win.
  • Pip’s Quest (OneTouch) – Experience a whole new level of creativity in this game that is nothing like video slots as we know them. There are nine separate screens. But, instead of reels, there are dice. The Quest Bonus takes you on an incredible journey where you roll dice to progress various levels.
