Solar Storm Slot Demo by Gm Studio

Solar Storm by Gm Studio Slot Overview

Solar Storm by Gm Studio pairs a cosmic backdrop with metallic panels and a humanoid robot. Its walking wilds share a mechanic with Knight Fall, but here Rogue Planets turn entire reels wild, move each spin and bounce off the edges.

The Supernova Bonus combines roaming planets, locking Quasars and Dark Energy crosses, with wild multipliers adding together on winning ways. High volatility and a 10,000x the bet maximum give this layered space slot its edge. Explore the features in the free demo on BonusTiime, without an account or deposit.

Solar Storm Slot Features

Solar Storm combines ways play, free spins, a Supernova switch, and four bonus buy options, all tied to roaming wilds and additive multipliers.

Free Spins

3 or more Magnetars anywhere on the board trigger free spins. Three land for 15 spins, 4 for 17, 5 for 20, and 6 for 25. During a standard bonus, 3 or more Magnetars retrigger 5 extra spins, up to 45 in total; the Supernova Bonus is capped at 40.

The Bonus Wilds

The bonus wild depends on the bonus round the game selects or buys, and the rules give each one its share. A winning way is multiplied by the sum of the multipliers of the wilds it crosses, so a x2 and a x3 make x5, and a way crossing none counts x1.

• Dark Energy (45% of bonuses): lands on reels 2-5 and bursts into a cross of wilds, its own cell and the four beside it, at x1, x2, x3 or x5.
• Rogue Planets (30%): exactly two full-reel wilds that move one reel every spin and bounce off the edges; each is x1, so a win through both counts x2.
• Quasars (25%): at least 3 Quasars lock their cell as a wild until the bonus ends, up to 15; the first is x2 and every later one x1.

Supernova Switch

The Supernova switch sits on the game screen, outside the bonus buy menu, and costs x1.25 the bet per spin while it is on. It puts the Supernova on the base reels, so when 3 or more Magnetars start the free spins with a Supernova on the board the Supernova Bonus starts instead of the random selector. It stays on until you turn it off and cannot change during a round or while autoplay runs. The Supernova pays nothing by itself and is neither a wild nor a scatter. The switch returns 96.51%, against 96.50% for the base game.

Supernova Bonus

The Supernova Bonus starts with 15, 17, or 20 free spins, never 25. It brings exactly two Rogue Planets, exactly two Quasars, and at least two Dark Energy crosses, all at x1. Retriggers add 5 spins, up to 40, and the bonus keeps the wilds already in play.

Bonus Buy

This feature lets you buy a bonus round directly instead of waiting for a natural trigger.

• Dark Energy: x100 the bet; starts with 15-25 free spins.
• Quasars: x120 the bet; starts with 15-25 free spins.
• Rogue Planets: x150 the bet; starts with 15-25 free spins.
• Supernova Bonus: x500 the bet; starts with 15, 17 or 20 free spins.

Solar Storm Slot Review

Solar Storm builds its identity from a deep space backdrop, a metallic interface and a clear solar system motif. The orbital lines, robot figure and glowing planetary symbols give the game a defined look, while Dark Energy and the Supernova switch make the theme matter mechanically, not just visually.

The gameplay has real substance because the board runs on 4,096 ways and high volatility, then layers in bonus buys and three different free spins variants. Walking wilds, locking wilds and additive multipliers keep the bonus structure varied. The downside is that the base game can feel spare before a feature lands.

Solar Storm puts much of its gameplay variety inside the bonus architecture rather than the base reels. The 10,000x cap and 96.51% RTP with the Supernova switch on give it proper range, and the Supernova Bonus is the clearest proof of that design focus. Confident but not flawless.
