It’s time to take a trip into the cosmos with Big Time Gaming’s slot Over the Moon. All the treasures of the galaxy await intrepid players who enjoy outer space-themed online slots. As with all Big Time Gaming slots, Over the Moon is an intricate, visually pleasing online casino game that is as rewarding as it is entertaining.

Doing your research is a vital step to take before you play any online slots for money. Get to grips with the details of Over the Moon in the review below.

Game Overview

Despite the title, the moon isn’t the focal point of this game, which is staged in a gorgeous outer space setting with a plethora of stars and rockets. This is a 6-reel Megaways-powered game, which means that there are no set paylines or ways to win. Instead, anywhere from 2–7 symbols will drop onto each reel with a ways-to-win system in place. Over the Moon offers a whopping 117,649 ways to win when the grid is maxed out.

This is a high-volatility online casino game with an above-average return to player (RTP) rate of 96.55%, and its features include wilds, multipliers, free spins, and enhanced free spins.

How To Play

As with all jackpot slots, you should start off by deciding on your bet amount before you play. The betting range for Over the Moon can be as little as $0.20 and as much as $50 per spin. 

The Megaways mechanics mean that this slot is different from your standard slot machine. When you press spin, 2–7 symbols will fall on the reels (depending on how many lines you’ve activated). To form a winning combination, you must land at least two adjacent symbols on the reels, starting from the left.

The lowest-paying symbols are the various playing cards, while the colored gems are the most valuable standard symbols and will pay out as follows for five of a kind:

  • Green gems: 1.5x.
  • Blue gems: 2x.
  • Red gems: 5x.
  • Purple gems: 50x.

Any winning symbols will disappear and make way for new ones to take their place, dropping down in the cascading feature typical of the Megaways mechanic. The game’s wild is the big “W” symbol, which will substitute for other standard symbols to help you form a winning combination.


Slots graphics have evolved over time, and while Over the Moon is hardly a cosmic feast for the senses, it has a compelling simplicity. BTG seems to have spent more time on the background and side features of the game than on the symbols and reels themselves.

The background is an interstellar smorgasbord of purple and blue gas clouds with plenty of shiny stars. The main animation comes in the form of the rockets that randomly appear to the left of the reels during the game to go up and down according to wins and losses.

The symbols themselves are fun and colorful.


Up to three flying rockets can land on the left side of the reels at any time during the base game. These have multiplier values of 1x, 5x, or 10x that can really boost your winnings. These multipliers will be added to any wins when the rockets are present. Each rocket has three fuel cells attached to it, which are lit up. Each time you fail to form a winning combination, a fuel cell will run out of power, and if all three run out, that rocket will be removed from the reels.

Meteor Prize

The Meteor Prize can land randomly during the game. Every meteor will display a cash prize value of up to 100x your stake. They’re awarded for every rocket in view and will also have the rocket multipliers added to the winnings.

Bonus and Jackpots

When you land three of the game’s scatter symbols, you’ll be awarded 12 free spins and two extra free spins for any more scatters on the reels. Free spins come with an Unlimited Rocket Multiplier. This means that the first rocket in this round will have a 1x multiplier, the second will have a 2x multiplier, and so on. There’s also the chance of a battery symbol randomly landing on the rightmost reel during the free spins, which will light up all your rockets to full power. 

If you land another three scatters during this round, you’ll get four free spins as well as two additional free spins for any extra. You can also pay for enhanced scatter symbols. If you land one as part of a re-trigger, you’ll be awarded 12 enhanced free spin. Rocket multipliers start at 2x and go up by increments of two per rocket.
