Astro Anna Theme
Casino enthusiasts are welcome to embark on a cosmic adventure along with Astro Anna who is on a mission to explore Mars. To reach the final destination, the fearless astronaut needs fuel. She will be by the player’s side helping to connect the copper fuel pipes properly and achieve substantial profits in the process. The playing grid of this intergalactic slot is a 5×5 configuration composed of copper pipes. With every hit of the play button, the pipes spin and may connect to return payouts.
The action takes place onboard a spaceship travelling in space. Lady Luck Studio has done a wonderful job in terms of artwork and animations. The game features distinctive cartoonish graphics that appeal to a large portion of casino players. Astro Anna stands by the left-hand side of the playing grid, with a laser gun in her hand, cheering on players whenever they score a win. As the spaceship travels, players see various planets, stars and comets. The audio is in absolute harmony with the adventurous theme of the game.
While the exciting Free Spins mode is on, the spaceship moves at a noticeably faster pace, and the music gets more energetic, preparing players for some big rewards.
How Astro Anna Compares to Other Slot Games
As the Pipe Mechanism is a proprietary feature of Lady Luck Games, it cannot be enjoyed in slots produced by other software studios. The feature was originally implemented in Mr. Alchemister, released a year before Astro Anna. It has an RTP of 95.6%, medium volatility, and three bet lines. The maximum achievable wins are capped at 100x the bet. Stakes fall within the range of 0.03 and 99.00.
When it comes to the space-inspired theme of the slot, however, players have a myriad of options to choose from.

Astro Anna Symbols and Payouts
As casino fans hit the play button, the pipes on the playing grid will start spinning in different directions. Due to the unconventional Pipe Mechanism in this slot, the symbols and their payouts are somewhat different.
There is one red entrance pipe located in the upper middle section of the playing grid. By hitting the play button, players strive to connect it to the other pipes to enjoy payouts. Therefore, all lines begin there and continue to the left, right, and bottom of the playing grid. There is a total of 11 different pipes, which should be connected properly to produce a payout.
To form a winning combination, a pipe must connect a Bet to a Prize. The connected pipes can lead players to one of fifteen prizes located in the left, right, and bottom sections of the grid. They amount to 0.5x, 1x, 1.5x, 2x, 5x, and 10x the total wager. If a pipe does not connect a Bet to any of these Prizes, then the spin is a non-winning one.

Bonus Features Overview
As already mentioned, there are no Wild and Scatter symbols in this unconventional slot. Their lack, however, is compensated by a variety of features including Free Spins, Multipliers, Buy Bonus, and Gamble feature. We will look further into their characteristics in the following lines.
Free Spins and Multipliers
Players get access to the Free Spins mode by hitting a minimum of four prizes in the same spin. The more prizes players manage to land, the greater their rewards will be. Four prizes in the base game trigger 10 Free Spins. Five prizes generate 15 Free Spins. Six prizes will produce 20 Free Spins. Hitting from seven to ten prizes in a single spin guarantees players 20 Free Spins and rising multipliers of respectively 2x, 5x, 10x, and 20x the bet.
Additional random multipliers can land on pipes. In case they appear on connected pipes, the wins are multiplied by the value of the respective multiplier. If several multipliers are collected, they will be added together.
Buy Bonus
If you are eager to launch the Free Spins, you can do so by taking advantage of the Buy Bonus feature of Astro Anna. Much like a great portion of Lady Luck Games’ slots, this intergalactic adventure is equipped with a shortcut to the exciting Free Spins round.
Players can choose between three options depending on the number of Free Spins they are willing to purchase. Ten Rocket Fuel Free Spins come at a cost of 40x the bet. Twenty Space Plumbing Free Spins are worth 135x the stake. The last alternative is called the Astro Extreme random option, as it brings a random combination of Free Spins plus Multipliers. It can be purchased against a price of 250x the wager.
Gamble Feature
The Astro Anna slot is yet another Lady Luck Games release equipped with a Gamble Feature. Players willing to risk the wins from successful spins can choose between two options. The first one involves a card colour bet, which can double their wins. The second option entails a card suit bet, which can produce a payout of 4x the bet.
