Astronomical, one of the games released by Microgaming, offers a fairly classic look, which is not surprising since it’s a 3 reel slot machine with 1 payline, but it has a sci fi element to it as well. The science fiction part comes from the image with stars in the background, and from the picture with the ringed planet. Otherwise, the layout is filled with two classic icons for each one that is regular. The top prize does look good, being at $40,000.

Betting & Jackpots

A wager placed in Astronomical will require at least 1 coin, but the maximum allowed will let you use 3 coins, so it’s not a huge range. The coin value starts at $0.25 and will reach $5 at most. You can spend as much as $15 on a single spin of the 3 reels.

Depending on the kind of wager that you’re placing, the results can vary. With a 3 coin wager, which is recommended, you can get up to 8,000 coins, or $40,000 cash. 2 coins will get you only 4,000 coins, or $20,000, so there is a bonus for the top jackpot when the wager is at its maximum. With 1 coin, the top reward offers you 2,000 coins, or $10,000.


The game might be a classic, but it doesn’t neglect the use of features, and it actually has a rather interesting one. The Astronomical Logo serves as the wild symbol in this game, and whenever it appears on a payline, contributing to the formation of a combo, it will also apply a multiplier.

There are three possible situations where the wild can be helpful. One of them is when the entire line has only wilds on it, in which case you win the top jackpot. Another one is where you have one wild and two matching symbols of another type, and there you get the wild’s 2x multiplier for that particular win. The third situation is with one regular symbol and two wilds, where the multiplier is at 4x.


I’m not a big fan of the design used here. While there are things like planets, or a star filled background, the rest of the design is still rather old, and the quality simply isn’t there. Still, for someone that prefers 3 reel games, this one is a notch above the rest.


The game has its advantages in the category it is in, especially related to the sci fi theme and the wild with its multipliers. The payouts aren’t bad either.
