Lord of the Ocean slot review

Lord of the Ocean slot in brief

Lord of the Ocean is one of Novomatic’s older video slots, from 2008, and it reaches online casinos through Novomatic’s online studio Greentube. It is a sea-god themed game built around a single symbol, Poseidon’s Gate, and one bonus round.

Novomatic was founded in 1980 by Johann Graf and is based in Gumpoldskirchen, Austria; Wikipedia’s Novomatic article (opens in a new tab) covers the group’s wider history. More classic line games are listed in our slot reviews hub.

How the features work

Poseidon’s Gate: wild and scatter in one

The Gate does two jobs. As a wild it stands in for other symbols to complete lines. As a scatter it counts towards the bonus wherever it lands. A single symbol type therefore drives both your line wins and your route into free games.

10 free games and the special symbol

Landing three or more Gates triggers 10 free games. At the start, the game picks one symbol at random to be the special symbol for the whole round.

Whenever that special symbol lands during the free games, it expands to fill its entire reel. Expanded special symbols pay in any position, so they don’t need to sit on a particular payline to count.

More free games

Landing three or more Gates again during the feature adds another 10 free games, with the same special symbol in play.

1. Land three or more Poseidon’s Gate symbols anywhere to trigger the feature.
2. One symbol is chosen at random as the special expanding symbol.
3. Play 10 free games; each time the special symbol lands, it fills its reel.
4. Expanded special symbols pay in any position.
5. Three or more Gates during the round add 10 more free games.

Expanding symbols: Lord of the Ocean vs Book of Ra Deluxe

If the feature sounds familiar, that’s because Book of Ra Deluxe, also a 2008 Novomatic game, uses the same idea: one symbol that is both wild and scatter, 10 free games and a randomly chosen expanding symbol. The two differ mainly in theme and in their published volatility.

Dolphin’s Pearl Deluxe takes a different route, with a multiplier rather than an expanding symbol. Read our Dolphin’s Pearl Deluxe review or the Lucky Lady’s Charm Deluxe review for that style.

Lord of the Ocean RTP: the cost of 250 spins

At 95.1% RTP the house edge is 4.9%, so the game is designed to keep about £4.90 of every £100 staked over a very long run. That is more than many of the newer slots we review, a lot of which publish 96% or above.

High volatility means real sessions rarely match those figures: much of the return arrives in occasional free-game rounds where the special symbol fills several reels. Between those, long quiet runs are normal. Our RTP glossary entry explains why the percentage only settles over a very large number of spins.

Lord of the Ocean on iPhone and Android

The online version runs in HTML5, so it works in iOS and Android casino apps and in phone browsers. A 5×3 grid with 10 lines is straightforward on a small screen, and full-reel expansions are easy to spot.

1. Finish your age and identity checks; UK apps need them before any play, demo included.
2. Search the app lobby for “Lord of the Ocean”. Novomatic games aren’t in every UK lobby.
3. Open the paytable to check the RTP, line wins and the free-game rules.
4. Choose a stake that lets your budget last; UK limits are £5 a spin at 25+, £2 at 18–24.
5. Spin one game at a time and glance at the net spend display as you go.

Is Lord of the Ocean fair to play online?

On a UK-licensed app, the game’s random number generator and maths must be tested before release. The Gambling Commission’s testing strategy (opens in a new tab) requires independent test houses to check games and RNGs.

Operators must also show you the rules and the likelihood of winning, under the game description standard (opens in a new tab). Fair here means random and as described; the 4.9% edge still applies. See do casino apps rig games? for more.

Lord of the Ocean slot verdict

Lord of the Ocean is a classic expanding-symbol slot with a clear, single bonus. It suits players who like the Book of Ra style of play and accept high volatility on a below-average RTP.
