    BetsRank Verdict

    Hands-on testing by Alexandre Dubois — bonus tested, multiple sessions

    Star Guardians is one of the few casino games where the production investment is visible on screen. Evoplay committed the biggest budget in its history to build a hybrid with few real equivalents: rooms to work through, manual aiming and, above all, three heroes whose boosters are more than cosmetic. Skyler's booster, which sidesteps the key requirement, genuinely changes how you approach a room, and being able to switch between heroes mid-game gives that choice a weight this format rarely carries. The official RTP of 96% holds within the market average and the advertised ceiling, around 5,000 times the stake on the boss sequence, is a serious number. The reservations concern pace: games run long, the Queen fight arrives on an irregular schedule, and no purchase exists to reach it faster. The 75 EUR stake cap is also lower than most of the catalogue. BetsRank suggests it to players curious about a genuinely different format.

    Strengths

    • +Hybrid shooter format still rare on the online casino market.
    • +Three heroes with genuinely distinct boosters, interchangeable mid-game.
    • +Boss fight advertised at between 50 and 5,000 times the stake.
    • +Official RTP of 96% within the market average.
    • +Careful production, the studio having committed its largest budget to date.

    To consider

    • No bonus buy: reaching the Queen fight depends purely on how a game unfolds.
    • Games run noticeably longer than on a classic slot.
    • No grid and no payline table, disorientating for a player used to reels.
    • Upper stake limit capped at 75 EUR per spin.

    About Star Guardians

    Star Guardians arrived in October 2021 and Evoplay presents it as the biggest-budget game in its history. The studio did not treat it as one more slot: the title is described as a hybrid between a casino game and a third-person shooter, with manual control over the character's movement and fire. Evoplay publishes an RTP of 96% and a maximum win of 377,175 EUR.

    There is no reel grid and there are no paylines. The screen shows randomly generated rooms populated by mutant insects called Tritons. The player eliminates those creatures to convert kills into wins, and works towards the objective the story sets out: facing the Triton Queen.

    Three heroes are playable and each is defined by a booster. Butcher fights with a multi-barrel machine gun and a rocket launcher; while his booster is active, every win is doubled. Skyler uses grenades and a sniper rifle; her booster opens valuable chests without needing a key. Kelliot channels kinetic energy as a weapon; his booster guarantees that the full haul is collected. Evoplay lets you switch hero mid-game, which turns that pick into a running decision rather than a setting chosen once at the start.

    Chests form the second layer of the game. Scattered through the rooms, they hold wins, amplifiers and keys among other things; the amplifiers trigger the selected hero's own ability for a limited time. Skyler's booster then makes sense: it sidesteps the key requirement the other two heroes have to satisfy first.

    The boss fight triggers at random during play. It runs in two stages: the player first holds off waves of larvae from a fixed cannon, then faces the three-headed Queen with the rocket ammunition banked during that phase. Wins attached to the sequence run from 50 up to 5,000 times the stake, which makes it the heart of the game's potential. During the bonus, eliminated Tritons drop either ammunition or money.

    The stake range recorded on the technical sheets runs from 0.10 EUR to 75 EUR per spin. There is no bonus buy: reaching the Queen depends purely on how a game unfolds. The volatility Evoplay shows spans a range from low to high, while specialist databases file the title on the high side, which fits the way the potential concentrates on the boss sequence.

    Put together, that structure shows where the game's money actually sits. Ordinary Triton kills are converted into wins as a run advances, but they are not where the ceiling lives. The chests, the amplifiers and the hero booster they switch on decide how much of a room a player converts, and the Queen fight, arriving at random and paying between 50 and 5,000 times the stake, is where the outcome of a session is settled. Picking a hero is therefore less a matter of preference than of reading what the current run is putting in front of you, which is precisely why Evoplay left the choice open mid-game.

    Key mechanics

    • Manual control over the character's movement and fire, as advertised by Evoplay.
    • Randomly generated rooms populated by mutant insects called Tritons.
    • Triton kills converted into wins as the run progresses.
    • Three playable heroes, interchangeable mid-game: Butcher, Skyler and Kelliot.
    • Butcher's booster: every win doubled for as long as it lasts.
    • Skyler's booster: valuable chests opened without having to find a key.
    • Kelliot's booster: the full haul is guaranteed to be collected.
    • Chests scattered through the rooms, holding wins, amplifiers and keys.
    • Random two-stage boss fight, larvae at the cannon then the three-headed Queen, paying 50x to 5,000x.

    Star Guardians FAQ

    What is the RTP of Star Guardians?

    Evoplay states 96% on the official game sheet, a figure that matches the market average.

    As across the studio's whole catalogue, the configuration actually deployed can vary by operator and by market. The rate shown in the game rules once the game is open remains the reference to work from.

    Is Star Guardians really a shooter?

    The studio describes it as a hybrid: a casino game carrying a third-person shooter layer, with manual control over movement and fire.

    The title is still categorised as a slot and rests on the same random generation principles as the rest of the Evoplay catalogue, whatever the controls suggest.

    What is the maximum win?

    Evoplay publishes a maximum win of 377,175 EUR on its official sheet.

    Specialist databases translate that amount into a ceiling of roughly 5,029 times the stake. The potential concentrates on the boss fight, whose wins are advertised at between 50 and 5,000 times the stake depending on how the confrontation ends.

    How does the boss fight trigger?

    It arrives at random during play, with no triggering symbol and no combination to land.

    The sequence runs in two stages: first waves of larvae to hold off from a fixed cannon, then the three-headed Queen, fought with the rocket ammunition banked during that first phase. Nothing in the base run brings it any closer.

    What separates the three heroes?

    Each has their own weaponry and their own booster.

    Butcher, with the machine gun and rocket launcher, doubles every win while his booster is active. Skyler, with grenades and a sniper rifle, opens valuable chests without a key. Kelliot, who channels kinetic energy, guarantees the full haul is collected.

    Can you switch hero mid-game?

    Yes, Evoplay states that changing character during play is possible.

    It is therefore not a setting locked in at launch: picking a hero becomes a running decision, adjusted to whatever the run puts in front of you. A player meeting a lot of locked chests can switch to Skyler, for instance.

    What are the chests and keys for?

    Chests are spread through the rooms and hold wins, amplifiers and keys among other things.

    The amplifiers activate the selected hero's own booster for a limited time. Some valuable chests need a key, which is what makes Skyler's booster worth having, since it opens them without that constraint.

    How volatile is the game?

    The official sheet shows a range spanning low to high, while specialist databases file the title on the high side.

    That reading fits the structure: ordinary kills bring back modest amounts, whereas most of the potential concentrates on the boss sequence, which arrives on an irregular schedule.

    Is there a bonus buy?

    No.

    Star Guardians has no buy function, and reaching the Queen fight depends purely on how a game unfolds. That is consistent with the nature of the title, whose boss sequence is built into a continuous run rather than presented as a separate bonus waiting to be triggered.

    What is the stake range?

    The game's technical sheets record a range from 0.

    10 EUR to 75 EUR per spin. The upper end is more contained than on other titles in the Evoplay catalogue. The amount actually available depends on the operator and the account currency, and can be capped while a bonus is under wagering conditions.

    Who is this game for?

    Mainly players coming from video games, comfortable with movement and fire controls and ready for longer sessions than a classic machine asks for.

    A player who wants a readable paytable and a fast rhythm will find a better-suited format among Evoplay's more conventional titles, of which the catalogue holds plenty.

    What happens to the Tritons during the bonus?

    During the boss sequence, eliminated Tritons drop either ammunition or money.

    Ammunition feeds the rocket supply used against the three-headed Queen in the second stage, so what happens in the larvae phase carries directly into the fight that decides the sequence and the potential attached to it.
