About Astronomical Slot

Much like the unique quality of space, Astronomical Slot is a one of a kind game that has survived the test of time.

It was first released by Microgaming in 1999. And until now, it is still one of the most enjoyable slot games. This may be because it continually offers players a safe place to come back to with all the hustle and bustle of five-reel 3d slot machines. It is still well-loved by younger and older players alike.

So, if you want a space adventure like no other, without all the complicated flashing lights of modern slot games, it is time to go back to the classics with Astronomical Slot. New and old players alike will surely enjoy this game.

Once satisfied with your bet, you are ready for take-off. Just click on the spin button to start your intergalactic journey.

To speed up your journey to a bigger jackpot, you can go all-in with the bet max switch. But remember, Astronomical is a classic slot machine, thus it will put emphasis on the number of coins you bet per turn and your wager.
