Astro Anna Slot Review

If you are ready to embark on a space adventure, you can have a few spins at Astro Anna. This unusual slot by Lady Luck will offer you plenty of chances to fight outer space creatures and stack up generous payouts.

There are several special features that can make Astro Anna extra generous and unlock bigger wins. This is a slot with medium to high volatility, which means that it is not unusual to go through numerous losing spins until you land a very generous payout.

Symbols and Winning Combinations of Astro Anna Slot

Winning CombinationsAs already mentioned, Astro Anna is a rather unusual slot when it comes to the way it awards wins. Instead of having specific symbols that will bring you different payouts for landing on a payline, with this slot, you will have pipe symbols connecting with each other, potentially leading to an exit with a prize at the end.

You will notice that the end of the slot has several exits, with different payouts on each end. The payouts that one can land include 0.5x, 1x, 1.5x, 2x, 5x, and 10x your total bet. It is possible to connect the main pipe to several exits, combining your wins.

A random multiplier can also be attached to some pipes, ensuring you an extra boost at the end of the winning pipe connection. The multipliers that can appear on pipes include 2x and 3x, but the best part is that you may have several multipliers attached to your wins, the value of which will be combined and applied to your overall win from the spin.

Unfortunately, Astro Anna does not incorporate any special symbols like Wilds or Scatters. That said, there are other ways to unlock the special features of the game.

Bonus Features of Astro Anna Slot

Bonus imageWhile the base game of Astro Anna can be very enticing, the big wins can be stacked up when the special features of the slot are unlocked. Whenever you connect the main pip to four or more exits, you will trigger the Free Spins feature of Astro Anna. The number of free spins awarded to lucky players depends on the number of winning connections that have unlocked the bonus game.

For four, five, and six winning connections, players will receive 10, 15, and 20 free spins respectively. For seven or more winning connections, players will enjoy 20 free spins, with a certain multiplier attached to the wins. For seven, eight, nine, or ten winning connections, players will enjoy a 2x, 5x, 10x, or 20x multiplier respectively applied to their wins during free spins.

Any time a multiplier lands on a winning connecting during free spins, the overall multiplier of the bonus game will be increased, with its cumulative amount added to the win. The new higher value of the multiplier will remain and will be applied to the following winnings from the Free Spins rounds.

If you have no patience for the bonus feature to be triggered when you land four or more winning connections, you can opt for Bonus Buy and activate the Free Spins options right away. This purchase, however, will cost you up to 250x your total bet depending on the options you would like to activate during the Free Spins. The least amount of free spins you can trigger is 10, with the Bonus Buy costing you 40x your bet. For 135x your bet, you will enjoy 20 free spins, and 250x your wager will award a Free Spins feature with a random option triggered during the bonus game.

There is also the Gamble feature you can have access to every time your winnings are equal to or less than 100x your wager. If you opt for this game, you will gamble your win in an attempt to double or quadruple its amount. During the Gamble Feature, you will have to guess either the color of a hidden card or match its suit. A correct color guess will double your wins while guessing the suit of the card will multiply your wins by 4. You can play the Gamble feature up to four times, provided your previous guesses are correct. A wrong guess, however, will cost you all of the wins you have gambled.


Astro Anna is a fun slot variation powered by Lady Luck, allowing players to collect winnings while having space battles. Even though the game lacks the typical paylines and winning symbol combinations, Astro Anna can still be very rewarding, especially when the Free Spins feature is triggered.
