Astro Legends: Lyra and Erion

Any fans of Synth Funk are going to want to check out the Astro Legends: Lyra and Erion slot game created by Foxium. The game was only released in November 2018, yet, the easy to play slot has drawn players in with the interstellar storyline which sees Lyra take centre stage with her basslines and beats while the landscape is a frozen ruin.

With 20 different ways to win the game, it is the perfect game for anyone who is just getting to grips with online slots. Yet, there are still plenty of features to make the game a little more progressive, this includes multiplier wilds, the Lyra Spirit Bonus and the Sonic re-spins feature. In the short time since the game was first published it has already been dubbed as one of the most innovative online slot machines due to the features and graphics. Even though the reels may appear a little different in the beehive formation, the game is still easy to understand.

Astro Pug

Astro Pug has been one of the most popular online slot characters of 2018, he features on the 8-reel slot which offers a staggering 1296 different ways to win.

With so many paylines, you’ll have to make sure you understand how to set the paylines before you make a stake. Few online slots rival how many features are included with Astro Pug. The Astro Pug himself acts as the wild symbol, once it pops up on the reels, the pug can act as substitute for all other symbols which pop up on that spin. There’s also a scatter symbol which can help you get your hands on some free spins. Even though there are plenty of interesting features on Astro Pug the return to player rate and winning potential are not all too high. So, high rollers may not enjoy Astro Pug as much as other games which feature on this list.

Reptoids was developed by one of the industry leaders in the online slot world; Yggdrasil. The game play was kept easy with the 5-reels and 3-row slots which offers players 20 different ways to win. The game set up has a fairly different theme to the rest of the sci fi games on this list, yet, it will be a hit with anyone who is keen to unmask the true identity of the reptoids. The game has a unique twist on the traditional online slot. A “detective window” will move across the reels as you spin them and stop on a symbol each time the reels come to a halt, if the detective reveals an alien, then the rest of the identical symbols will also act as wilds. Therefore, in this game, the wild is not the symbol, but the window. You’ll want to look out for the Commissioner to appear in the reels, if you spot him, you could win up to 1000 coins. The RTP for Reptoids has also been reasonably set at 96.1% and there are plenty of free spins to get your hands on during the gameplay.
