A complete guide to Ocean King, the multiplayer fish-shooter that defines arcade gaming on the Mega888 platform. How the skill-influenced RTP works, weapon strategy, fish values, and honest tips for new shooters.
Ocean King is the most-played arcade game on the Mega888 platform and the title that introduced a whole generation of Malaysian players to the fish-shooter format. Unlike a slot — where outcomes are pure RNG — Ocean King is a skill-influenced game. Where you aim, when you fire, and which cannon level you use all affect your real-world return. The published 95% target RTP is what skilled players approach over time; less experienced players will see lower returns until they learn the patterns of fish movement and weapon efficiency.
This review covers how Ocean King actually works on the Mega888 app, what each fish is worth, how to choose cannon levels intelligently, and where this title sits in the broader library.

A multiplayer arcade fish-shooter where you fire bullets at fish swimming across the screen. Each fish caught pays out a multiple of your cannon’s bullet cost. Boss fish offer big payouts for skilled or lucky players willing to commit firepower.

Ocean King’s published target RTP is approximately 95%. But unlike a slot, where every spin is purely random, your actual return is influenced by skill — meaning the gap between target and personal RTP can be wide.
Each fish on screen has a hidden HP value and a fixed payout multiplier if you kill it. A small fish might take 1–2 bullets and pay 2× your bullet cost. A boss fish might take 100+ bullets and pay 50–500× when you land the killing shot. The maths inside the game is set so that across millions of bullets fired by all players combined, the total payout averages around 95% of total bullet cost. That’s the published target RTP.
What this means for you personally: if you spam bullets randomly without aiming, you’ll waste shots on fish you don’t kill (the killing shot collects the payout, not the wounding shots) and your personal return will be well below 95%. If you aim carefully, target wounded fish, and avoid wasting bullets on tough fish you can’t finish off, you’ll track much closer to the target RTP. Genuinely skilled players can occasionally do better than 95% over a session, though variance is high and luck matters too.
Ocean King is fast-paced and chaotic at first, but the core flow is simple. Here’s the start-to-finish for new players.
Find Ocean King under Arcade Games in the app. You’ll be placed into a multiplayer lobby with other live players. Get the app first from the official download hub if you haven’t installed it.
Cannon levels run from 1 to 7. Each level costs more per bullet but deals more damage per shot. Lower levels are better for small fish; higher levels are needed for bosses and big game.
Tap on a fish to aim at it; bullets fire automatically while you hold. Whoever lands the killing shot collects the payout — wounding fish that another player kills earns you nothing. Aim selection matters as much as fire rate.
The game offers special weapons like nets (catches everything in an area for one large bullet cost), lightning (chains between fish), and missiles (high damage on a single target). These cost more but can be efficient against the right targets.
Bosses appear periodically with very high HP and payouts. Only commit to a boss if you have enough credit to finish the kill — otherwise you waste bullets on damage that doesn’t pay. Watch other players’ fire patterns; piling on a boss with the room can be efficient.
Choosing the right cannon level for the right fish is the single biggest skill factor in your return. Here’s the basic logic.
Low bullet cost, low damage. Use for the smallest fish that die in 1–2 hits. Wasting high-level bullets on a fish that pays 2× is bad maths. Most casual play happens here.
Balanced damage-to-cost ratio. Good for mid-tier fish that pay 5×–15× and for catching schools where multiple fish line up in your bullet path. The workhorse range for experienced shooters.
High bullet cost, high damage. Only justified when targeting bosses or very high-HP fish where lower levels would waste too many bullets to finish the kill. Don’t sit at level 7 for casual play.
Different fish have very different payout-to-HP ratios. Knowing which fish are efficient targets matters as much as aiming well.
Small fish (clownfish, butterfly fish, small tropical fish) have low HP and low payouts — typically 2×–5× your bullet cost. They’re the bread-and-butter targets when using low cannon levels. Medium fish (lobsters, turtles, larger tropical fish) take more shots but pay 8×–20×, making them efficient mid-cannon targets. Special fish like the lantern fish or “lucky” variants carry small bonus features — bombs that damage nearby fish, or screen-clear effects.
Boss fish (sharks, mermaids, dragons depending on the build) have very high HP — often 100+ bullets at mid-cannon levels — and pay 50×–500× when killed. The maths only works in your favour if you’re confident you can finish the kill before running out of credit, or if other players in the lobby are committing fire to the same boss. A boss you wound and abandon pays nothing.
Ocean King is multiplayer — you share the lobby with 3–5 other live players, all firing at the same fish. This affects strategy in important ways.
Only the player who lands the killing shot collects the payout. Wounding a fish another player kills earns you nothing. This means timing and target selection matter — sometimes it’s smarter to chase the fish others are wounding than to start fresh on a new one.
Bosses are usually too tanky to kill solo at reasonable cannon levels. Watching other players’ fire and joining in on a boss they’ve damaged can be efficient — you contribute to the kill cost share, but increase the chance someone in the lobby finishes it within your credit reach.
