Astro Anna Features

Astro Anna is not your typical online slot as you must match up pipes to the top instead of lining up paylines. There are 11 pipe symbols in the game with each of the pipes able to connect to each other to form a win. There are 6 different prizes to be won in the game with the biggest 10.00.

In addition to the pipes, there is a free spins round. If at least 4 different prizes are hit in the same spin, the free spins round. Up to 20 free spins can be triggered with multipliers as well.

The full breakdown includes:

Finally, there is a gamble feature that is triggered after every single win. You have the opportunity to risk it all and gamble to increase your wins. This can be done up to four times. There are two options to gamble with red or black, or choosing the card suit to increase the win bet by four times.

Astro Anna Review

Space is a rare area that has yet to be fully explored. That was until Astro Anna set off to find out the mysteries of the world and see if there is alien life out there.

Embark on this space adventure with Lady Luck Games' Astro Anna. Unlike most other slots, this game plays on a grid of 5x5 with wins being made up by pipes being connected.

There is nothing ordinary about this slot making it perfect for seasoned fans of slots. This mechanic is similar to the fan-favourite Mr. Alchemister, so be sure to keep on reading if that's a slot you love.


When the journey begins, players will find a spaceship moving throughout Space with different planets and stars in the distance. Sadly, the controls of the aircraft are quite bland and dark which is a strange twist.

Astro Anna stands next to the reels looking like a character from The Jetsons with the 1960s design. She is animated and comes to life at times which is a cool attention to detail.

Unfortunately, the design of the pipes and the spaceship do seem a little strange compared to Anna and the space theme. It does feel a little disconnected at times.

Despite this, the music is absolutely fantastic. Throughout spins, there is a science fiction score playing with a techno beat paired with synth sounds that really rounds off the slot.


With the pipe mechanic, this slot definitely feels refreshing. Despite seeing this mechanic before with Mr. Alchemister, the feature still feels fresh and exciting. On top of this, there are still free spins, multipliers and a gamble feature to keep the slot simple.

All the buttons you need in this slot are the spin button and the bet level button. At the bottom of the screen, you'll be able to find the sound settings and paytable buttons.

Win Potential

Unfortunately, the win potential statistics are not what you'd expect with Lady Luck Games. However, it's worth bearing in mind that this is not a typical slot therefore we must look at the statistics from a different perspective.

The RTP is under the average at 94.10% which is not the RTP we'd like to see. This is accompanied by medium to high volatility levels and a maximum win of 2,500x the stake.

Whilst this is not a huge amount by typical slot standards, throughout the gameplay it does feel like a huge amount that has value. During our gameplay, we only managed to win up to 500x the stake and this felt massive.

Our Verdict

When opening up Astro Anna, we had no idea what to expect. Thankfully, we were pleasantly surprised with the outcome and the fact that this slot is not your typical game.

Whilst we do wish the pipe feature felt a bit more cohesive visually with the slot, the gameplay was thrilling and felt enriching at times. Overall, our experience was fantastic and we couldn't wait to go back.

Pipes: An original mechanic from Lady Luck Games

Every slot developer is constantly working to master the next mechanic. Since Big Time Gaming won over the iGaming world with Megaways, developers have been scrambling to find great alternatives.

Lady Luck Games has gone in a completely new direction with its unique pipes mechanic found first in Mr. Alchemister and then now in Astro Anna. This forgoes the typical format on online slots with reels and instead adds in a new mechanic.

How does the pipe system work?

For the past two examples, this pipe system works with a grid of 5x5. On this grid, there is a pipe at the top of the screen in the middle that connects to other pipes to form a win. If this connects to the cash symbols around the screen, then a win is guaranteed.

There are literally only 6 different prizes to be won but multiple prizes can be won at once. In these slots, there are often other accompanying features such as free spins, multipliers and the gamble feature.

A refreshing mechanic for the iGaming world?

Whilst this slot plays on a grid, it is not like Cluster Pays or other grid mechanics. Lady Luck Games describes it as pipe connections where pipes must be connected in order to solidify a win.

This has only ever been seen with Lady Luck Games and turns a slot from something dull into something extremely refreshing. There is no telling where this mechanic will go but it'll certainly satisfy players.

If this sounds like the mechanic for you, then be sure to try out Mr. Alchemister and Astro Anna when it releases on slot sites on the 20th of October 2022.
