Neptune S Champions Slot Review
Neptune stands at the edge of the reels in gold armour and a blue fishtail, a red octopus curling its tentacles over the pillars of his sunken temple behind him. High 5 Games have built their underwater court around an unusual idea: the base game matters here more than the bonus. Every spin of Neptune S Champions feeds a set of meters that grow across your whole session, which means the game starts working before anything triggers.
It’s a 5×3 slot with 40 paylines running at 96.0% RTP, and the free games round, when it arrives, inherits everything the base game has built. The studio’s catalogue runs from 88 Drums to Da Vinci DeluxeWays, but this one leans hardest on the long build. There’s no maximum win figure for this one.
Paying Symbols and the Meters Above the Reels
Wins pay left to right across 40 fixed lines, with line wins multiplied by the bet per line. Scatter symbols award in any position on the reels. Three amphora-style meters sit above the reels, and they’re the heart of the game rather than decoration: wins from high-paying symbols are multiplied by whichever meter corresponds to them.
Stand back and the meters change how you read a spin. A five-of-a-kind Helmet win on its own is a modest 40 credits, but if the Helmet’s meter has been fed well, that same line pays several times over. The wild substitutes for all symbols except the Bonus symbol and appears only on reels 2, 3 and 4. Symbol pays look like this:
- Jackpot: 50 for three, 100 for four, 1000 for five
- Dolphin: 20 for three, 40 for four, 200 for five
- Dragon: 15 for three, 30 for four, 150 for five
- Golden creature: 15 for three, 30 for four, 150 for five
- Helmet: 8 for three, 20 for four, 40 for five
- Dagger: 8 for three, 20 for four, 40 for five
- Emerald Shield: 8 for three, 20 for four, 40 for five
The Base Game Multiplier Feature
Each of the three meters corresponds to three symbols, and one of them starts at 5x rather than 1x. How a meter grows, step by step:
- A line win lands with one of the meter’s featured symbols.
- That line contributes points equal to the number of winning symbols on it, so a five-of-a-kind feeds the meter five points.
- The wild counts as whichever symbol it’s standing in for when points are tallied.
- Every 40 points contributed raises that meter by 1x.
- After all points are contributed, wins with the featured symbols pay at the meter’s current value, and wins with the Jackpot symbol pay at the sum of all three.
That last line is the hook. The Jackpot symbol already sits at the top of the paytable, and the combined weight of three grown meters lands on top of it. A long enough run of featured wins turns a modest symbol into something considerably bigger.
The points come only from the featured symbols themselves, so a screen full of low-value gems pays nothing into the build. That gives the featured set a second job beyond what they pay directly: they’re the fuel, and the gems are just change.
The Crystal Ball
A Crystal Ball scatter lands only on reel 5 during the base game, and it isn’t collected for its own sake: every ball banked is spent in the next Free Games Bonus, raising a random meter by 1x each before the count wipes back to zero. It’s the bridge between the two halves of the game.
Because each ball raises a meter at random, you can’t steer where the boost goes. What you can do is time the bonus: walking in with a handful of stored balls guarantees several extra points of meter value before a single free game has resolved, and the count then starts collecting again from zero for the bonus after that.
One stake rule matters here. All feature progress earned applies only at that total amount bet, so changing your stake means the meters don’t carry across. Players who like to move their bet size around will keep restarting the build.
The Free Games Bonus
Three or more Bonus symbols anywhere on the reels starts the Free Games Bonus, and the award ladder is a short one:
- 3 Bonus symbols: 7 free games
- 4 Bonus symbols: 12 free games
The round plays on different reels to the base game, on the same lines at the same bet per line as the spin that triggered it. Nothing about your stake changes going in, which keeps the Crystal Ball carry-over clean.
Multiplier Meters in the Bonus
Inside the bonus, the three meters each correspond to two symbols instead of three, so the mapping you learned in the base game shifts. Any Crystal Balls collected beforehand raise a random meter by 1x each, and from the second free game onwards, every meter has a random chance to grow by 1x at the start of a spin.
The payout side works as before, with a bonus-round twist: featured-symbol wins pay at their meter’s value, while the Jackpot symbol pays at the combined total of all three meters. With meters growing on their own each spin, the later free games carry more weight than the early ones.
The round can’t retrigger. Free games don’t award additional free games, and the bonus simply ends when none remain. Everything rests on how far the meters have climbed by the final spin, which is what gives those collected Crystal Balls their value.
Our Honest Verdict
Overall Rating: 7.6/10
Sitting in front of Neptune S Champions feels less like waiting for a bonus and more like tending something. That’s the reason to pick it: the meters make a session feel like it’s going somewhere, even when the free games are nowhere in sight. The drowned-temple scenery is easy on the eye without ever being the point.
Its strength is the Jackpot symbol paying the sum of all three meters, which rewards the whole build rather than one lucky line. Its weakness is that the bonus is a fixed-length affair, so a round that arrives before the meters have grown can pay like an afterthought. That’s a sting when you’ve spent an hour feeding the amphorae.
This is a game for players who enjoy the build itself, and who’ll hold one stake long enough to let the meters do their work. It’s not for anyone who wants a retrigger chain or frequent bonus rounds. Neptune’s ocean rewards patience, and there’s real pleasure in that if it’s yours.
