About this Slot
Nebula Vault is a space and sci-fi themed slot from Generous Gaming with an RTP of 96.05%, medium volatility and a maximum win of 25,000x. The game uses 5 reels, 3 rows and 10 paylines.
The Astrolabe feature locks one reel as wild and respins the others. The feature stops when no new symbols land or when reels 2 to 4 are locked.
Star Maps trigger free spins and hold the first grid. The count of Star Maps landed determines both the spin mode and the number of spins awarded.
Comet Trail awards 8 free spins. During this mode, the comet sweeps row cells to turn them wild each spin.
Star Pulse awards 12 free spins with fixed wilds on reels 2 and 4. Every five spins, a special behaviour repeats. If 3 or more Star Maps land during Star Pulse, an additional 5 spins are added.
Nova Burst awards 12 free spins. One symbol is pulled and then copied to turn wild, while a multiplier increases through the feature.
Event Horizon awards 10 free spins where all wins are multiplied. The multiplier caps at a ceiling and the feature ends immediately once that ceiling is reached.
Celestial Alignment is a single pick round where twelve dials are revealed sequentially. Each dial shows either an award or a multiplier, with all awards summed and multipliers applied to the total.
