Crashing waves and sub aquatic sounds are the backdrop for Neptune’s Kingdom: a three reel online slot with five paylines and a watery collection of crustaceans, sunken treasures, and nautical goodies.

This is a classic fruit machine with no frills, no scatters, no wilds, and no bonuses or feature rounds. It’s old school online slots action. However, like many of the ‘basic’ games, it comes with a generous return to player percentage of 97.19%. In other words: come in, the water’s lovely.

Symbols in play on the Neptune’s Kingdom online slot include a hoard of sunken treasure, mermaids, tridents, lobsters, and selected fish. The treasure is the jackpot which pays out at 150x. The treasure chest also pays in all horizontal and diagonal directions. You can wager up to $20 a line on Neptune’s Kingdom and bet between 1 and 5 lines.
