Do images of riches come to mind when you hear the name Neptune? Does searching for underwater treasure sound exciting? Do you enjoy playing both picking bonus rounds and free spin bonus rounds? If so, the Neptune’s Kingdom slot game is the perfect game for you!

Players will be swimming in earnings when they are launched into the Treasure Chest Bonus. This round is triggered when 3 or more scattered Treasure Chests appear on the reels. Dolphins swim across the screen to begin the bonus. Neptune then appears along with 12 treasure chests. The player is awarded 5 Treasure Chest Picks. In each of Neptune's chests hides a free spin or a multiplier of 1X to be added during the free spin part of this bonus round. When the player has used all his picks, free spin reels appear and the player plays through. Re-trigger of the free spins is available during this bonus, as well as the Coin Bonus!

Dive into the Coin Bonus when 3 or more scattered Coins land on the reels. This first-screen bonus allows the player to choose among spinning coins to receive an award. Once a coin is chosen, it will stop spinning and slowly fall down to reveal the winnings. Awards consist of a multiplier, and a back door into the Treasure Chest Bonus!

Another exciting feature of this game is the Expanding Wild Neptune symbol. This symbol is available on reels 2, 3, and 4. If the Wild Neptune symbol lands on one of these reels and can create a new winning combination by expanding, it will grow to make the entire reel wild!
