What is Space Mutants?

Space Mutants forms wins through clusters of at least 5 matching symbols connected horizontally or vertically anywhere on the grid. After every win, the winning symbols are removed and new symbols fall into the empty positions, potentially creating additional clusters within the same round.

Each spin begins with a 1× multiplier. After every successful cascade, the multiplier increases by 1 and the new value is applied to the win from that cascade. In the base game, the multiplier resets to 1× once the full cascade sequence ends.

Cluster wins and Cascading Symbols

Space Mutants does not use traditional paylines. A winning combination consists of at least 5 identical symbols connected horizontally or vertically.

When a winning cluster is formed, those symbols are removed from the grid. The remaining symbols drop down and new symbols fill the empty spaces.

This process continues for as long as each new cascade creates another winning combination. A single base-game spin can therefore contain several consecutive cascades.

Incremental Multiplier

Every new spin starts with a 1× multiplier.

After each winning cascade, the multiplier increases by 1. Consecutive wins can therefore be paid at 2×, 3×, 4× and progressively higher values as long as the cascade sequence continues.

When no further win is created, the sequence ends and the multiplier resets to 1× for the next base-game spin.

This mechanic becomes more important during the Space Chaos Bonus because the multiplier does not reset between individual Free Spins.

Mutant Surge

A Mutant Surge meter with 5 sections is displayed next to the grid. Each consecutive cascade fills one section.

When all 5 sections are filled after 5 consecutive cascades and the current cascade sequence then comes to an end, Mutant Surge is activated.

The feature places one or more 2x2 Giant Wilds on the grid. The guaranteed win created by the Giant Wild immediately fills the first section of a new Mutant Surge meter.

After the activation, the meter can therefore begin building again through further cascades.

Astro Mutant

The Astro Mutant symbol can appear in both the base game and the bonus game. Its feature is applied after all existing cascades and wins have been resolved.

When activated, the Astro Mutant itself transforms into a Wild and one of two additional effects is applied.

The first effect adds 2 extra Wilds on two consecutive reels within the same row. Together with the Astro Mutant, this creates a total of 3 Wild positions.

The second effect selects one random low-paying symbol. Every visible instance of that symbol is then transformed into a Wild, while the Astro Mutant itself also becomes a Wild.

If neither additional effect can be applied, the Astro Mutant simply transforms into a Wild.

Space Chaos Bonus

The Space Chaos Bonus is triggered by landing 4 or more Scatter symbols in the base game.

Four Scatters award 10 Free Spins, 5 Scatters award 15 Free Spins and 6 Scatters award 20 Free Spins.

During the Space Chaos Bonus, the same Cascading Symbols, Mutant Surge and Astro Mutant mechanics remain active as in the base game. The main difference is the multiplier: it does not reset to 1× between Free Spins.

A multiplier built through cascades during one Free Spin therefore carries over to the next and can continue increasing throughout the bonus.

Astro Mutant during the Space Chaos Bonus

During the bonus, the Astro Mutant gains an additional possibility. Alongside one of its regular Wild effects, the feature may also add an extra multiplier to the current bonus multiplier.

Possible Astro Mutant multiplier values are 2×, 3×, 4×, 5×, 7×, 10×, 20×, 50× and 100×.

This value is added to the current multiplier before it is applied to any wins. Combined with the multiplier already built through cascades, the total multiplier can therefore continue to increase throughout the Space Chaos Bonus.

Wild symbol

The Wild symbol substitutes for all regular paytable symbols and can therefore help complete clusters and extend cascade sequences.

Scatter and Astro Mutant symbols have their own functions and are not replaced by the Wild.

Building Mutant Surge again

After Mutant Surge is activated, the meter resets, but the guaranteed win created by the Giant Wild immediately fills the first section of the new meter.

This means a strong cascade sequence can start building towards another Mutant Surge almost immediately after the previous activation. The meter itself resets at the start of each new spin.

Why Space Mutants stands out

Space Mutants stands out through the way several progressive mechanics reinforce one another.

Cascades increase the multiplier, the same cascades fill the Mutant Surge meter, and the Astro Mutant can create additional Wilds. During the Space Chaos Bonus, the accumulated multiplier also remains active between Free Spins.

This creates a clear chain of interaction: clusters create cascades, cascades raise the multiplier and build Mutant Surge, while Wild effects can help create further clusters.

Is Space Mutants worth playing?

Space Mutants is designed for players who enjoy cluster mechanics, cascades and bonus features that can build over an extended sequence.

This NowNow Gaming release via Hacksaw OpenRGS combines Mutant Surge, Astro Mutant, a persistent bonus multiplier and a maximum win of 10,000× the stake.
