What Is Mermaid Fishing?
Most online casino games ask you to sit back and watch the reels spin. Mermaid Fishing on rk777 is different. It's an active, skill-influenced fish shooting game where you control a cannon, choose your targets, manage your ammunition cost, and decide when to go after the big bosses. The result is something that feels genuinely engaging rather than passive — and that's a big part of why it's become one of the most popular games on rk777 among Bangladeshi players.
The setting is a vivid underwater world filled with dozens of different sea creatures, each carrying a different prize value. Small fish are easy to hit and pay modest amounts. Larger creatures take more shots but reward you proportionally more when they go down. And then there are the special targets — the Mermaid Boss, the Giant Crab, the Electric Eel — that can produce the kind of payout that makes a session genuinely memorable.
rk777 hosts Mermaid Fishing as part of its core arcade game lineup, which means it's always available, always fast-loading, and always connected to the same wallet you use for every other game on the platform. One account, one balance, one withdrawal — straight to bKash or Nagad.

RandomOcean Depth Zones
Mermaid Fishing on rk777 is divided into three depth zones. Each zone has its own set of creatures, its own visual atmosphere, and its own prize ceiling. You move between zones by increasing your bet level — higher bets unlock deeper water and more valuable targets.
Arsenal
Choosing the right cannon for the right target is the core skill in Mermaid Fishing on rk777. Each weapon has a different cost per shot, fire rate, and area of effect.
The entry-level weapon. Low cost per shot, single-target fire. Ideal for clearing shallow-water fish quickly and building up your balance before moving to deeper zones on rk777.
Fires three shots in quick succession at a slightly higher cost per burst. Excellent for hitting fast-moving targets like the Electric Eel before it changes direction.
Fires a wide arc of five projectiles simultaneously. Lower damage per shot but covers a large area — perfect for clearing schools of tropical fish in a single burst on rk777.
A slow-firing, high-damage weapon that deals massive single-target damage. The go-to choice for taking down the Giant Crab and other heavily armoured mid-tier targets efficiently.
Creates a spinning vortex that pulls nearby fish toward the impact point and deals area damage over two seconds. High cost, but exceptional value when multiple high-tier targets are grouped together.
The most powerful weapon in Mermaid Fishing on rk777. Unlocked in Zone 3, it fires a three-pronged trident that pierces through multiple targets in a line. The only weapon capable of one-shotting the Mermaid Boss at maximum charge.
Special Features
Beyond the standard shooting gameplay, Mermaid Fishing on rk777 includes several special events that trigger during a session and can dramatically increase your winnings in a short window of time.
Mermaid Boss Raid
A timed event where the Mermaid Boss appears on screen for thirty seconds. All players in the room can fire at her simultaneously. The player who lands the killing shot claims the full 500x prize — making it a genuinely competitive moment on rk777.
Treasure Chest Frenzy
Multiple treasure chests spawn across the screen at once. Each chest contains a random multiplier between 5x and 200x your shot cost. You have fifteen seconds to open as many as possible before they sink back into the deep.
Electric Storm
Triggered randomly in Zone 2 and Zone 3. Lightning strikes the water, stunning all fish on screen for five seconds and doubling the prize value of every target defeated during the stun window. Timing your shots during an Electric Storm on rk777 is one of the most effective ways to maximise a session.
Free Shot Bonus
Awarded randomly after defeating a Giant Crab or Electric Eel. Gives you ten free shots at your current weapon's power level with no ammunition cost deducted from your balance. Any prizes won during free shots are credited in full.
Prize Reference

Player Tips
Even experienced players benefit from a few minutes in shallow water. It lets you calibrate your aim, get a feel for the current fish movement patterns, and build a small buffer in your balance before moving to the more expensive deeper zones on rk777.
The Mermaid Boss has enormous health. Firing at her solo with a Standard Cannon will drain your balance before she goes down. Wait for the Mermaid Boss Raid event, upgrade to the Mermaid Trident, or coordinate with other players in the room to bring her down efficiently.
When an Electric Eel is near a group of other fish, defeating it triggers a chain shock that damages everything nearby. One well-timed shot can effectively clear a cluster of targets for the cost of a single kill — one of the best value plays in Mermaid Fishing on rk777.
The Vortex Cannon is expensive per shot. Using it on a single fish is wasteful. Hold it until you see three or more mid-tier targets in close proximity, then fire into the centre of the group. The area damage and pull effect will handle the rest.
When the Electric Storm event triggers, every target on screen is worth double. Switch to your highest fire-rate weapon and clear as many fish as possible in the five-second stun window. This is the single best moment to maximise your return per shot on rk777.
Because Mermaid Fishing charges per shot rather than per spin, it's easy to lose track of how much you've spent. Decide on a maximum number of shots — or a total spend — before you open the game. rk777 lets you set deposit limits in your account settings to help with this.
If a Treasure Chest Frenzy produces a significant win, consider withdrawing a portion before continuing. Locking in profit means the session stays positive regardless of what happens next. rk777 withdrawals to bKash and Nagad arrive in minutes.
