Supernova Galaxy Orbs Features & Mechanics

Red Orb Hold & Win Feature
Landing a Red Orb triggers the Hold & Win feature after any base game wins have been paid. The feature begins with 3 respins, referred to as lives. During the feature, only Red Orbs, Jackpot Symbols, Coin Symbols, and Dead Symbols can appear. Whenever a Red Orb, Coin, or Jackpot Symbol lands, it sticks in place and resets the respin counter back to three. Dead Symbols have no value and simply occupy positions on the grid.
Coin Values
Coin Symbols award cash prizes as multipliers of your bet.
- Bronze Coins: 0.2x, 0.4x, 1x, 2x
- Silver Coins: 3x, 4x, 5x, 10x
- Gold Coins: 15x, 20x, 25x, 50x
- Diamond Coins: 100x, 150x, 200x, 250x, 500x, 1,000x
Coins remain on the reels until collected by a Red Orb.
Jackpot Symbols
Jackpot Symbols also remain on the reels until collected.
Once the Hold & Win feature ends, each Jackpot Symbol reveals one of the fixed jackpot prizes:
- Mini – 10x
- Major – 50x
- Mega – 500x
- Grand – 5,000x (Maximum Win)
Only one Jackpot Symbol can appear during a single respin.

Red Orb Collection
After all Coin and Jackpot values have been determined, every Red Orb activates by collecting the value of every Coin and Jackpot Symbol currently on the grid. During the Hold & Win feature, up to three Red Orbs can be active at once. Each Orb independently collects every available value, meaning the same Coin or Jackpot can be collected multiple times if multiple Red Orbs are present. Orbs activate from left to right, then top to bottom.
Blue Orb Feature
The Blue Orb can appear during the base game. After any regular wins have been paid, each Blue Orb collects the value of every Coin and Jackpot Symbol currently on the reels, awarding the combined total as an instant payout.
If multiple Blue Orbs land together, each one performs its own collection, allowing the same Coin and Jackpot values to be collected multiple times. Up to three Blue Orbs can appear on a single spin. Blue Orbs and Red Orbs cannot appear together.
Sphere Factor Free Spins
Landing 3, 4, or 5 Bonus (FS) Symbols awards the Sphere Factor Free Spins feature.
- 3 Scatters: 10 Free Spins
- 4 Scatters: 15 Free Spins
- 5 Scatters: 20 Free Spins
The bonus retains all of the base game’s mechanics while increasing the chance of triggering the Red Orb Hold & Win feature. In addition, every Coin Symbol is guaranteed to be worth at least 1x your stake.
Additional Bonus Symbols can also award extra Free Spins:
- 2 Scatters: +3 Free Spins
- 3 Scatters: +5 Free Spins
- 4 Scatters: +7 Free Spins
- 5 Scatters: +10 Free Spins
