Lord of the Ocean by Greentube is a 5-reel, 3-row video slot set in an underwater Greco-Roman scene. The game uses 10 fixed paylines, with royal-themed high-value symbols, classic card icons, and a central wheel scatter displayed on a gold-framed grid.
Landing 3 or more scatter symbols awards 10 free games. During the free games round, one special symbol is chosen at random as an expanding symbol, able to cover three positions on a reel and pay across active lines, including non-adjacent wins. Free spins can be retriggered by additional scatters, and the rules note that the demo version can be used to practice before playing for real money.
After a winning spin, the gamble feature offers a red-or-black choice to try to double the payout. The slot review format near the demo launcher makes it possible to play for free and study the bonus game mechanics, paylines, and symbol behaviour before placing real stakes.
