Sea-Themed Casino Games

What the Sea theme covers

This theme groups casino games with sea-related subject matter. It has a large selection, made up almost entirely of slots, alongside a few Slingo, instant games, and bingo titles. Slingo combines slot-style play with a bingo card; instant games resolve through a short action, while bingo centers on matching called numbers to a card. These formats give players more than one way to browse the theme.

Games Global, Light & Wonder, IGT, and Bragg are among the studios with the biggest presence. The examples below are all slots, but the wider theme also includes the other game types mentioned above.

Sea-themed slots and their RTP

Atlantis Megaways from Reel Play is a slot with a 96.1% RTP and medium volatility. Marlin Masters by Hacksaw Gaming is also a slot; its RTP is 96% and its volatility is medium. NetEnt's Secrets of Atlantisโ„ข has a 97.1% RTP and medium volatility. Ancient Fortunes: Poseidon Megaways from Games Global has a 94% RTP and medium volatility.

RTP is a theoretical long-run average for one game configuration, not a prediction for an individual session. Operators can use different configurations, so check the game's information panel for the RTP that applies when playing. Volatility describes the pattern of a game's results; it does not predict the outcome of a session.

Comparing the Sea games

Use the live list to compare titles, and sort by RTP when you want to order games by that theoretical figure. Then check volatility as a separate measure of how results are distributed. Neither measure predicts what will happen in a particular session. Read a game's rules for its specific mechanics before playing.

Availability depends on the market and casino. Visit the casino comparison page to check where games can be played, or browse the full slot games list for more titles in that format.
