This really is a simple game where re-spins, multipliers and free spins are your only extra features. Here is how it works.
Phantom Power Re-Spins With Sticky Wilds
Keep your eyes out for that elusive Phantom Power wild which is the ghost-ship in yellow. Not only is it wild, but when it lands it also trigger a re-spin where it is sticky on the reels. At the same time, this ghost ship will battle those in adjacent positions. And if it wins, it turns them wild too, triggering a further re-spin.
Free Spins With Multiplier Wilds
The scatter symbol here is represented by the buried treasure chest. Landing 3, 4 or 5 will earn you 10, 12 or 15 free spins. During the round all your wilds are sticky, and IF you can reach a point where every reel has a wild on it, then you’ll earn yourself 5 extra spins.
Also, the Phantom Power feature is active during free spins too, so wilds may turn other ships into wilds if they win their battles. And … wilds may have 2x or 3x multipliers with them during free spins too!
