Neptune’s Secrets Slot Review

Mermaids, fish, and a mighty god welcome you to the Neptune’s Secrets slot machine. This gorgeous game plays out across five reels, three rows, and 25 paylines, where a wild octopus helps you to grab extra wins. Tridents point the way to free spins where all wins are doubled in value.

A World of Beauty and Mystery

Dive into the Neptune’s Secrets online slot and discover a world of stunning graphics. The animated symbols include a goldfish, nautilus, seahorse, and bright crystals. A mermaid and the Roman god of the sea appear in equally impressive detail against a watery, mermaid-filled backdrop. A dramatic soundtrack is a perfect match for the epic subject of Roman mythology.

Treasures in the Deep

Although the bright pink octopus doesn’t pay direct prizes, it’s a valuable wild symbol with the power to substitute for others and help create extra winning combinations. 

The Neptune’s Secrets online slot is a casino game with free spins, triggered by three or more trident symbols in any places at once. You get ten bonus spins that retrigger if enough tridents land at the same time. It’s here that you can get your tentacles on the biggest wins, as all prizes are doubled throughout. 

Other Gods of the Sea

Other games making a splash at the best casinos include the Neptune’s Kingdom slot machine by Playtech and the Enchanted Mermaid online slot from NextGen Gaming.

Adventure in the Abyss

The return to players percentage is slightly low, but not too far off the mark, and the 25.00 maximum bet may put off higher stakes players. If these are not an issue for you it’s a game we recommend, where the highly impressive graphics of the Neptune’s Secrets slot machine match with simple but rewarding features. 

Wild substitutions and free spins with multipliers are hardly new, but if you want to enjoy a great-looking slot with well-established gameplay then this could be the answer. Take the plunge and play the Neptune’s Secrets slot online at the best sites.
