What Makes Over the Moon Special?

Over the Moon is not just another space-themed slot adventure. In fact, the slot distinguishes itself from other Megaways slot games with the innovative rocket multiplier system. These rockets can land on the reels at any point, with fuel cells powering their flight. They stay on the grid until the fuel cells deplete, playing their role in cascades several times.

This can create a lot of momentum that can turn into massive wins. Moreover, the slot’s bonus round is supplemented with a super free spins bonus, which can be triggered by mega scatters. In short, its winning potential sets it apart from the crowd, so it’s neither a simple space adventure nor a bland Megaways slot. This is best done by trying the slot for free at the best casinos on our list.

Since it’s developed by the mechanic’s original creator, it shows how the mechanic works in the best possible form. BTG went for a truly polished space aesthetic, with a background that features nebulas and stars and colourful gemstones on the reels. The animations and audio work in perfect sync, so Over the Moon feels like true rocket science.

Game Mechanics and Features

Over the Moon uses the Megaways engine, having a 6-reel grid with up to 7 symbols per spin. Landing the highest number of symbols ensures the highest number of Megaways, of which there are up to 117,649. Bets range from 20c to $50 per spin, meaning the slot accommodates players of all types. Wins are formed traditionally for a Megaways slot when matching symbols land on adjacent reels from left to right.

Symbol Breakdown and Features

The symbols sets in Over the Moon feature a colorful collection of space gems along with space-themed low-paying card royals. They’re accompanied by wilds, scatters, and super scatters, as well as the all-important rockets. The highest-paying symbols pay up to 50x for six of a kind. Wilds can step in and keep tumbles going.

As expected, cascades are in the focus. All wins trigger a cascade where winning symbols are removed and replaced with a new set. This will keep going for as long as there are winning combinations on the screen. A gold star serves as the scatter, while the purple star is a mega scatter that can trigger an enhanced version of the bonus round.

Rocket Multipliers

The rocket multipliers are one of the slot’s special features. They can land randomly on the grid carrying multipliers of x1, x5, or x10. Each rocket also carries up to three fuel cells. When a win occurs with an active rocket, the multiplier applies to it. Each reaction causes the rockets to lose one fuel cell, and once they’re used, the spin sequence ends.

Up to three rockets can be active at the same time. Their multipliers combine for even better winning combinations. With cascades in the mix as well, it’s easy to see how rewarding this feature can be.

Meteor Prizes

Meteors can also strike the reels, displaying various cash prizes. These can go as high as 100x the bet. The meteors only pay when there’s at least one rocket active beside the reels. Their prizes are boosted by the rocket multipliers, giving players a chance to win substantial cash prizes.

Battery Symbols

Batteries can also land randomly on the reels. They refuel the rockets, keeping them in the game for longer. With fully loaded rocket fuel cells, this mechanic can turn losing streaks into winning opportunities.

Free Spins Feature

Landing three plus scatters triggers the bonus round. It starts with a dozen free games, and each scatter over the minimum of three for a trigger provides extra bonus features. These may be extra wilds or other enhancers. During the free games bonus, the rockets gain progressive multipliers instead of fixed ones.

The multiplier values jump up by +1 for each rocket. There’s no upper limit on the progression system, so theoretically, they can reach x50 or higher. Three or more scatters during the bonus retrigger the feature.

Enhanced Free Spins

Triggering the bonus round with at least one mega scatter activates the enhanced version. The premium bonus works like the standard feature, but the rocket multipliers go up by +1 instead of +1 for every new rocket landing on the grid.

Our Over the Moon Testing Experience

The Hazreviews team tests every slot on our website for real money to determine its value and show our readers how rewarding it is. Over the Moon was tested in three phases – a conservative and high-roller approach, with a mid-stakes session sandwiched between them. You can check the results below.

We began with a low-roller conservative approach and bets of 50c over 200 spins. The base game action proved engaging thanks to cascades and frequent rocket appearances. On average, a rocket landed ever 8-12 spins, boosting our prizes up to 32 times for combined multipliers. The bonus round came on spin 167, producing a payout of 87x. Smaller base game wins later kept our bankroll intact, but overall, the high volatility proved a challenge and we ended this session with a loss of $31.

For the mid-stakes session, we increased the bet to $1 per spin. We lowered the number of spins to 180. Rockets appeared with similar frequency, and the bonus round came on spin 92. We were lucky to trigger the enhanced version, with an accumulating multiplier that reached 14x after a respin on free spin number eight. Prizes weren’t that impressive, hitting a maximum of 82x. However, during a memorable sequence, we landed a 143x win, resulting in a profit for this session of $435.

For the final test, we played 150 spins at $2 each. The high volatility was quit evident, with the first 80 spins barren. A bonus round followed at almost 100 spins, with a modest 43x payout. Another trigger came at spin 134, with an extension and rockets that produced larger wins. In the end, we made a profit of $192, showing that luck plays a big part in the bonus rounds.

Over the Moon Slot Strategy Tips

Like all online slots, Over the Moon is a game of chance. This means that the results are random, so there’s not much strategy you can use. However, understanding how it works and what pays the most can help you get the most out of your sessions.

We recommend keeping a bankroll that allows for at least 300-400 spins on a standard bet. The high volatility means you’ll experience dry spells and wild swings, and you’ll need to weather the storm. Cross your fingers to maximize reactions during the base game. Every extra cascade brings extra profit, and with rocket prizes, these cascades can be truly rewarding.

The bonus round can pay plenty, especially if it’s the enhanced version. But getting there might be a grind, and that’s why you need something slightly more than a casual bankroll size.
