If there ever is an alien invasion we would prefer to get invaded by the aliens from the Astro Rocks slot. Microgaming has made these grid-based critters lovely and beneficial, as they can trigger massive payouts by forming big clusters and with the help of a number of reel modifiers. This is a fun to play game with features that bring out the best of this payout system. 

Astro Rocks Introduction

Players can discover a very exciting game that comes with an excellent base game and avalanche wins. There is a wild symbol that substitutes for all regular symbols and there are few reel modifiers such as symbol swaps and symbol destruction events. All of the above is towards a reel adventure that can generate potentially massive payouts resulting from a single bet. 

Astro Rocks Design Features

In terms of graphic design Microgaming and their partner studio have made a game that is quite dynamic and comes with engaging gameplay. Most players, in our humble opinion, are going to find the aliens adorable. These represent the high paying symbols of the game, while the low paying symbols are various space matter such as asteroids, star clusters, planets and cubes. 

Astro Rocks slots marks hte winning outcomes with a 'bang'. The symbols crackle and pop, however, the most exciting effect comes with the cube that creates a black hole that causes surrounding symbols to warp and disappear, before bringing about a new set, depending on the modifier. Overall, it is a fun game to play and it may even unseat Jammin' Jars slot as one of the favorite cluster-pay slots out there. 

How to Play Astro Rocks

In addition to a cheerful tune that accompanies the gameplay, the player can enjoy few standard options that are part of modern slots. For example, the autoplay mode is one way to play Astro Rocks slot. This enables players to relax while the game does the playing on its own. 

It's really a beautiful display of the mechanic and the payout system in one when the clusters go on to perform their dance and the avalanches towards winning outcomes. 

When configuring the options, the game makes it possible to add a number of controls that prevent the balance from dipping too low or it makes an announcement when the bonus feature has triggered. 
To stop the autoplay mode simply press the same button again. 

The thunder button that can be found to the right of the spin button lets players toggle on faster spins. Another look to the right is the poker chip button which opens up a list with the available bets from which players can choose their wager.

Last but not least, there is the menu button in the bottom left corner of the screen and this leads to the settings options and to the paytable where players can view symbol payouts. 

How to Win Astro Rocks Slots

Winning outcomes in this game are made possible when at least five symbols of the same kind have landed on adjacent rows. Between five and ten matching symbols can constitute small payouts. Between 11 and 25 symbols form medium payouts and more than 30 symbols trigger big wins.

The high-paying symbols of Astro Rocks slot are represented by the aliens. The wild symbol is a cube that is stuffed with energy but can also perform few other exciting events on the grid. 

Astro Rocks Bonus Features

The game doesn't come with a free spins bonus even though it is quite possible to land multiple winning outcomes in a row. This is one way to trigger a free spins bonus in grid-based slots, but not Astro Rocks. Another possibility is clearing the entire grid, which again, doesn't trigger free rounds.

Where the game compensates for the lack of that bonus feature is with the wild. This symbol can trigger black holes that swallow alien symbols, which in turn grants payouts. Black holes can link up in combo moves and expand across multiple areas of the grid, towards more effective winnings. 

Another feature is with the alien symbols' ability to level up, which is always an exciting event to witness on the grid. Upgraded aliens means bigger payouts. 

Astro Rocks Free Play

The game is available as a free play demo slot at online casinos that host Microgaming games. Playing the game in practice play makes it possible to experience the gameplay and get a sense of the features before deciding to play with real money.

Astro Rocks Closing Thoughts

Overall, it is an amazing game to try and even call your favourite, as it is definitely amusing to watch and provides engaging gameplay. The black holes are the event to behold because these can trigger the big wins. One game that has a similar level of dynamism compared to Astro Rocks is the Bombuster slot, which has more reel modifiers compared to this game.
