astronomical slotThere is such a wealth of advanced video slots with lots of cool features at online casinos, yet spinners still get nostalgic about the past when one-arm bandits were practically the only option for those looking to set the reels in motion. If an old-school slot is what you are looking for, Microgaming’s Astronomical may be the perfect game of choice for you. The slot is played across three reels, three rows and a single payline.

Standard symbols are in use to award you with a payout. We are all familiar with the classic bells, bars, and cherries but Astronomical also utilizes a funky planet symbol and its own logo as the highest payers. The slot supposedly borrows its name from the astronomical payouts it rewards spinners with as it offers a rather appetizing jackpot of 8,000 coins.

Being a retro one-arm bandit, Astronomical does not have much to offer in terms of additional features and special symbols. Still, Microgaming’s developers have decided to include a wild in the game which can be used as a substitute for other icons on the reels. Players are presented with the option to stake anywhere between one and three coins on each spin, with flexible values ranging between $0.25 and $25.00 but limits may vary between casinos utilizing Microgaming’s cutting-edge platform.

Special Symbols

The layout of Astronomical resembles that of the traditional one-arm bandits that took over landbased casino floors several decades ago. That is to say, there is no need to exit the base game in order to view the payouts of winning combinations – the paytable is conveniently positioned within the main game screen. It contains information on the number of credits one is awarded for different symbol combinations when betting one, two or three coins per spin.

The Astronomical logo awards the largest payout of 8,000 credits for three matching symbols on the solitary payline. But it plays yet another important role, that of a wild which substitutes for all symbols with no exceptions. This “astronomical” wild can also quadruple profits as it comes with a 4x multiplier on winning combinations, consisting of two such symbols. If you land only one astronomical wild on the payline, your winnings will be doubled with a 2x multiplier. Another great thing about this Microgaming offering is that it pays for two matches only – line up two cherries on the payline and you get even money for single-coin bets and a return of three coins when max betting.

Bonus Games and Features

Since Astronomical is as old-school as it gets, players can hardly hope for an abundance of great extra features and bonus games. No such functionalities are present in this simplified slot except for the wild with the 2x and 4x multipliers, which is still something as it helps boost your wins and form more matches.

There are two ways for spinners to alter the number of coins in play per spin. You can either use the Bet One button in the control panel at the bottom of the screen or directly click on one of the three columns in the paytable, which we consider the faster and more convenient option. By hitting Max Bet, you automatically stake three coins of your denomination of choice. Players can, of course, regulate the size of the coins in play by using the “+” or “-” buttons.

There is a small blue button that reads “Expert” and by clicking it, players can unlock the Autoplay feature of Astronomical. There are not many options here. In fact, there you can play anywhere between 5 and 500 spins without interruption.


Astronomical may be an old-school title lacking in lots of the features modern slots can present you with. Still, it is fair to say albeit old, the game has aged incredibly well and remains a favorite of many spinners who give its reels an occasional whirl in an attempt to harvest the flat jackpot of 8,000 coins. Besides, there is a wild symbol which can also multiply one’s winnings on lucky spins and this still counts as something.

It should be noted that simplicity actually works to Astronomical’s advantage as its clear-cut layout and straightforward gameplay render it a fitting option for reel novices, who might end up confused by all the extra features, lumped together in many of the modern video slots. Not much is going on in Astronomical and therefore, this classic title is the perfect start for those who are making their first steps in betting on virtual slot machines.

The audio effects are also quite retro as they mimic the authentic sounds of the bells and whistles of one-arm bandits across brick-and-mortar casino floors. So if you are longing for a truly old-school experience, simplified gameplay, and a reasonable theoretical return percentage, Microgaming’s Astronomical may be the right slot for you to pick. Give its three reels a whirl, just for the nostalgia if nothing else.
