How the Starburst Galaxy pokie works
Wins use NetEnt's Avalanche mechanic: winning symbols are cleared and the gaps refill, so one spin can pay several times. A wild appears at the centre of each winning combination and substitutes for everything except scatters, which keeps chains going. Three to five wilds that do not form a win still pay by the paytable.
The Feature Generator
Every five consecutive wins award one of five random features: Destroy, Random Wilds, Expanding Wilds, Line Transform or Upgrade. This is the game's engine. Long Avalanche chains feed it, and each award makes the next win more likely.
Galaxy Star and Mega Star
The fifth Feature Generator award triggers Galaxy Star. The grid expands to 7x7 and a 3x3 Starburst wild is placed on it. A Galaxy Metre fills with each win, and at 50 the Galaxy Star is awarded again. Separately, three scatters in one spin trigger Mega Star, which places a 2x2 Starburst wild; some scatters carry multipliers from x2 to x25 that fill a Multiplier Collect Metre and apply to every win for the rest of the round.
Elevate buy options
Where allowed, NetEnt's Elevate Feature sells five entries: Bonus Boost at 3x the bet, Mega Star at 10x, Boosted Mega Star at 50x, Galaxy Star at 100x and Galaxy Star Bonanza at 500x, which starts with five features already awarded. At A$1 a spin, the top option costs A$500.
