Alien Robots online slot game

The cute robot aliens are taking over in NetEnt’s simple yet fun slot game, Alien Robots. It’s a perfect starting point for anyone first trying out the slots as the in-game features are simple to understand. Saying that, the 10,000x top prize multiplier might sway a few seasoned slots players to take a closer look, along with the interchangeable 30 and 243 payline feature which helps to boost the game’s winning potential.

Theme and Storyline

Alien Robots is a simple and straightforward slot game and there is no set storyline to be explained. The game is based around the in-game symbols with the Wilds and Scatters being the only bonus symbols that you need to pay attention to. Free spins and extra multipliers make up the main features of the game with the extra opportunity to extend the standard 30 paylines up to 243 ways with the click of a button. This is a clever addition to the game and something that seasoned players will no doubt take advantage of to increase those winning possibilities and potential payout prizes.

Graphics, Sounds and Animations

NetEnt has decided to keep the graphics and animations to a minimum here and offer a game that is simple in both looks and gameplay. The alien robot symbols are neatly designed in a cartoon style against the basic lower value card symbols. Animations are only apparent when you win bigger prizes with the robots being given a short animated clip to announce your winning payline.

In terms of the soundtrack, the computerised beeps sit well with the theme but a main song during gameplay is missing. NetEnt is a studio known for their immersive gameplay and so a missing soundtrack is something that becomes obvious as soon as you open up the game, but it doesn’t distract so much to ruin the entertainment altogether.


Alien Robots comes with a customisable payline with 30 as standard and a boost up to 243 is available via the game controls underneath the reels. The layout is based on five reels and three rows with a set of low and high value symbols. The low-value are in the form of the playing card icons of 10 to Ace, with the alien robots taking the form of the high-value symbols; the blue, grey, yellow, orange, and red robot.

It’s the red alien robot that attracts one of the biggest prizes in the game with up to 10,000x your line bet. The orange robot gives you a 5,000x multiplier, the yellow 3,000x and the grey robot 1,000x your line bet. The Alien Robots game is certainly not short of big payouts with even the lower value blue alien robot providing a 500x multiplier when five of them land on the reels. As we previously mentioned, the bonus features in the game are based around the Wild Alien and Scatter UFO symbols and we’ll explain these next.

Bonuses and Free Spins

The UFO Scatter symbol triggers the free spins feature with three or more landing on the reels from a single spin. Three scatters come with 10 free spins, four gives you 20 spins, and five gives you a huge 50 spins in total. The Wild Alien symbol is designed to substitute all of the symbols in the game except the Scatter symbol. In addition, it also becomes a sticky and expanding Wild during the free spins feature.

As an extra feature in the game, you are given the choice of 30 paylines or 243 ways. You can make this change using the payline selector in the bottom left hand corner of the game screen. Although the paylines increase dramatically, the payout prizes do decrease in size so you’ll need to way up your options before you go ahead and play with 30 or the full 243 paylines.

Bet sizes, RTP and Variance

The minimum bet per spin is €0.20 and this increases up to €75 per spin with the 30 paylines or €150 per spin with the 243 ways activated. The RTP of the slot game is set to 97.60% with a medium variance. Alien Robots is a simple game to play that offers a balanced mix of small and bigger wins through the in-game robot symbols and the free spin feature.


Alien Robots is the perfect option for players just starting out in the slots world. The simple bonus features and the choice of paylines is a nice way to understand how a typical slot machine works. That said, with 10,000 multipliers and expanding wilds, the game offers enough features for players of all experience to come and spin the reels.
