Developer Lustrous Ocean by SimplePlay is a fishing-themed slot with five reels and a staged progression system. The game places players in an underwater setting where gem-covered fish and Fish Kings act as the main targets. A demo version is available to play for free, giving users a way to learn the mechanics and practice before playing for real money.
The game includes a Free Bullet Wheel that can trigger free bullets and payout multipliers of up to 5x. At Stage III, Fish Kings appear as Stage Bosses, and defeating them leads to a Bonus Stage with variable payouts reaching up to 1000x. Progress between stages depends on reaching set fish or winnings targets, with branching paths that can change the next scenario.
Additional features include three Gem Powers: Freeze, Summon and Machine Gun. Each power must be charged through the gauge before use. The slot also supports switching between portrait and landscape mode during play.
