What Is Mermaid Fishing at 99x04?
A full-featured underwater arcade fishing game where skill, timing, and a bit of fortune combine to deliver big multiplier wins — straight from your phone or desktop browser.
Mermaid Fishing is one of the most played arcade-style games at 99x04, combining vivid underwater graphics with real-money wagering mechanics that reward both casual players and focused, experienced shooters. Unlike traditional slot games where you spin and wait, Mermaid Fishing puts you in direct control — you aim a cannon at fish swimming across a richly animated ocean scene and fire bullets to catch them, with each caught creature paying out according to its designated multiplier.
The game draws heavy influence from the classic fish table arcade machines found in gaming halls, but brings everything online in a browser-native format optimised for the Bangladeshi market. There is no app to download — you open the 99x04 website on your Android or iOS device, log in, navigate to the Mermaid Fishing section, and you are playing within seconds on Grameenphone, Robi, Banglalink, or any Wi-Fi connection across Dhaka, Mymensingh, Khulna, and beyond.
The "mermaid" theme gives the game its signature visual identity: a luminous deep-ocean backdrop populated not just with fish, but with mythical sea creatures, treasure chests, glowing jellyfish, armoured crabs, giant squids, and — the centrepiece — the legendary Mermaid boss herself, who commands the highest multiplier on the board and requires concentrated firepower to defeat.
At 99x04, Mermaid Fishing tables seat up to four players simultaneously, each controlling their own cannon independently. This social element sets the game apart from solitary slot play — you can see other players' cannons firing in real time, and coordinating fire on a high-value boss creature creates a genuinely shared experience that resonates with the communal spirit Bangladeshi players bring to every gaming session.
Why Mermaid Fishing Stands Out at 99x04
- Skill-based shooting mechanics — aim matters, not just luck
- Multipliers from 2× for common fish up to 999× for legendary bosses
- Multiple cannon levels and special weapons to choose from
- Live multiplayer — up to 4 real players per table
- Deposits and withdrawals in BDT via bKash, Nagad, Rocket
- Fully mobile-optimised — no download, no app store required
How to Play Mermaid Fishing at 99x04
New to fishing arcade games? This step-by-step walkthrough covers everything from registering your account to landing your first big catch.
Register and Verify Your 99x04 Account
Sign up on 99x04 with your mobile number, name, and date of birth. Complete the one-time KYC verification by submitting your National Identity Card (NID). Verification typically clears in two to six hours. You must be 18 years or older to play Mermaid Fishing or any other game on 99x04.
Deposit BDT via bKash, Nagad, or Rocket
Fund your account using Bangladesh's most popular mobile financial services. The minimum deposit is ৳500 and funds are credited instantly — send from the bKash or Nagad app to the 99x04 merchant number and your balance updates within 60 seconds. No currency conversion needed; everything runs in BDT.
Navigate to Mermaid Fishing
From the 99x04 homepage, click the Mermaid Fishing menu item. The game lobby loads directly in your browser — you will see available tables, the current number of players seated at each, and the table betting range. Choose a table that matches your preferred stake level.
Select Your Cannon and Bet Per Bullet
Before you start shooting, configure your cannon. Choose a cannon tier (standard, powered, or special) and set the BDT amount you want to spend per bullet fired. A higher bet per bullet increases the BDT value of every fish you catch by the same multiple — so a 500× fish caught on a ৳20 bullet pays ৳10,000, whereas the same fish on a ৳50 bullet pays ৳25,000.
Aim and Fire at Fish
Tap or click anywhere on screen to aim your cannon in that direction and fire. Fish swim across the screen in groups and patterns — smaller common fish move quickly in schools while larger rare and legendary creatures move more slowly, giving you more time to land multiple shots. Each bullet fired deducts the set bet amount from your balance immediately.
Collect Winnings Instantly
When you successfully catch a fish, its multiplier value multiplied by your active bet per bullet is credited to your balance immediately — there is no round-end wait. You can withdraw winnings at any time via bKash or Nagad with payouts processed within 15 to 30 minutes for verified accounts.
First-Timer Tip: Start on the Lowest Bet Table
When you first open Mermaid Fishing, resist the temptation to jump straight to high-value cannons. Start with the minimum ৳10 bet per bullet and spend your first session learning which fish move in predictable paths, where the boss creature spawns, and how your chosen cannon's bullet spread pattern works. Mastering the mechanics on low stakes will pay dividends when you move up to higher bet levels.
Mobile Controls
On mobile, tap anywhere on the game screen to fire toward that point. Tap and hold to enable auto-fire mode — your cannon continuously fires at the locked target position while you hold. This is useful for sustained fire on a slow-moving legendary creature. On desktop, use mouse click to aim and fire, or right-click to lock auto-fire direction.
Fish Tiers and Multipliers in Mermaid Fishing
Every creature in the Mermaid Fishing ocean carries a fixed multiplier. Know your targets — the difference between a 2× clownfish and a 500× sea dragon is the difference between small wins and life-changing payouts.
The Mermaid Fishing game world at 99x04 is populated with creatures across four distinct rarity tiers. Common fish appear in high volume and are easy to catch but pay modest multipliers. Rare and epic creatures appear less frequently, require more bullets to defeat, but reward proportionally larger wins. Legendary bosses — the Mermaid Queen and the Ancient Sea Dragon — appear on timed spawn cycles and require concentrated, sustained fire to bring down, but their multipliers are the highest available on the entire board.
Clownfish
2×Fast-moving in large schools. High catch rate, good for building balance steadily.
Starfish
3×Slow and easy to hit. Usually appears in groups of four to six near the screen edges.
Shrimp Swarm
5×Appears as a cluster target. A single shot that hits the cluster centre catches all shrimp simultaneously.
Octopus
20×Moves unpredictably — changes direction every few seconds. Requires patience and anticipation to catch consistently.
Giant Squid
50×Large hitbox but fires ink clouds that briefly scatter bullets — requires a burst-fire approach to overcome its ink defence.
Armoured Crab
80×High health pool — the shell absorbs multiple hits before the crab is defeated. Use powered cannons for efficient catches.
Golden Dolphin
150×Rare spawn that dashes across the screen in a straight line. You have a narrow window to intercept it — aim ahead of its path, not at it.
Crystal Whale
300×Slow, enormous target — easy to hit but demands a huge bullet investment to defeat. Coordinate with other table players for best results.
Mermaid Queen
500×The signature boss of the game. Spawns every 8–12 minutes, activates a shield phase, and rewards the player who lands the killing shot.
Ancient Sea Dragon
999×The rarest and highest-value target on the board. Extremely high health, appears only once per game session. Max multiplier available.
Coral Guardian
200×Stationary target that appears near coral formations. High value for its relatively short defeat time — great risk-to-reward ratio.
Electric Jellyfish
40×Pulses with electric charges that can briefly stun your cannon between shots. Target it quickly or switch to another fish while your cannon recovers.
Cannons and Special Weapons in Mermaid Fishing
Choosing the right cannon for the right target is the single biggest strategic decision you make in every Mermaid Fishing session at 99x04.
The cannon system in Mermaid Fishing is what separates it from pure luck-based games. There are several cannon classes available, each with different bullet spread, fire rate, and damage characteristics. Upgrading to a higher-tier cannon costs more BDT per bullet but dramatically increases your damage output per shot — making it efficient against tanky targets like the Armoured Crab, Crystal Whale, and Ancient Sea Dragon. Sticking with a basic cannon on common fish, however, keeps your spend per kill low and your profit margin per session healthy.
| Cannon Type | Bullet Spread | Fire Rate | Best Target Tier | BDT Cost Multiplier |
|---|---|---|---|---|
| Standard Cannon | Single shot, narrow | Fast | Common & Rare | 1× base bet |
| Double Barrel | Two parallel shots | Medium-fast | Rare & early Epic | 2× base bet |
| Spread Cannon | 5-bullet fan spread | Medium | Schools & Rare clusters | 3× base bet |
| Laser Cannon | Piercing beam — hits all fish in a line | Slow (charge-up) | Epic bosses | 5× base bet |
| Torpedo Launcher | Explosive area-of-effect on impact | Slow | Legendary bosses | 8× base bet |
| Thunder Storm | Chain lightning — jumps between nearby fish | Very slow (cooldown) | Dense schools & Legendaries | 10× base bet |
Frenzy Mode
When you hit five consecutive catches within 30 seconds, Frenzy Mode activates for 15 seconds — your cannon fires at double speed and bullet cost stays the same, effectively halving your cost-per-damage during the burst window.
Golden Bullet
A randomly awarded special bullet that appears in your inventory once every few minutes. The Golden Bullet deals 10× normal damage on the single shot it is used — save it for the Mermaid Queen or Ancient Sea Dragon for maximum impact.
Electric Net
A special one-use weapon that temporarily stuns all fish on screen for 3 seconds — giving you and your tablemates a clear window to rapidly fire on any target without it moving. Extremely effective when the Crystal Whale or Mermaid Queen is on screen.
Depth Charge
Detonates a large explosion at a targeted point on the screen, dealing heavy area damage. Particularly effective against Shrimp Swarms and Starfish clusters — a single well-placed Depth Charge can clear an entire group in one shot.
Ricochet Shot
A bouncing bullet that deflects off the screen edges and continues travelling until it hits a fish or exhausts its bounce count. Useful in the mid-game when fish are near edges and standard shots are difficult to angle correctly.
Lock-On Missile
Automatically tracks and pursues the highest-value fish currently on screen after being fired. Higher cost per use but eliminates aim error entirely — ideal for mobile players who find precise targeting difficult on small screens.
Bonus Features and Special Events in Mermaid Fishing
Beyond the standard fishing gameplay, 99x04's Mermaid Fishing includes a rotating set of bonus events and special features that supercharge potential winnings during limited windows.
Treasure Chest Bonus
Sealed treasure chests drift across the screen periodically. Shoot one open to reveal a random prize — ranging from a small instant BDT credit to a full fish-value multiplier bonus applied to your next catch.
Ocean Storm Event
A timed 90-second event during which all fish multipliers are doubled site-wide. Storm events are announced with an in-game visual warning 30 seconds before activation — position yourself and select a high-tier cannon before it begins.
Boss Rush Challenge
A special 5-minute game mode where four Epic and Legendary creatures spawn in rapid succession with no common fish filler. Entry costs a fixed BDT amount and all players at the table compete for the highest catch value during the window.
Daily Fishing Bonus
Log in to 99x04 daily to claim a free Golden Bullet or small bonus bullet credit for Mermaid Fishing. The reward scales with your account activity level — more active players receive higher-tier daily rewards.
Tips and Strategy for Bangladeshi Players
Mermaid Fishing rewards players who approach it with a plan. These practical tips are tailored for players in Dhaka, Chittagong, Sylhet, and across Bangladesh playing on mobile data or home Wi-Fi.
Manage Your Bullet Budget per Session
Before you start, decide on a maximum BDT spend for the session and stick to it. A practical rule: never set your bet per bullet at more than 1% of your session budget. If you deposit ৳2,000 for a session, keep your bet per bullet at ৳20 or below. This gives you 100 shots of room to manoeuvre — enough to encounter multiple rare and epic spawns without exhausting your balance before a high-value target appears.
Don't Spray Bullets at Fast Common Fish
New players waste a large portion of their budget firing rapid volleys at the fastest, smallest fish in an attempt to rack up quick wins. The return rate on common fish barely covers bullet cost at mid-tier cannon settings. A disciplined player focuses fire on medium-value rare creatures (Octopus, Electric Jellyfish, Giant Squid) that offer solid multipliers without requiring the heavy cannon investment that legendary bosses demand.
Coordinate on Legendary Bosses
When the Mermaid Queen or Ancient Sea Dragon spawns, communicate with your table — even through the in-game emoji reactions — to concentrate all four cannons on the boss simultaneously. A coordinated four-player burst using Torpedo Launchers and Thunder Storm weapons can defeat the Ancient Sea Dragon in under 20 seconds, making the 999× multiplier genuinely achievable within a normal session without an excessive individual bullet spend.
Stable Connection Is Critical on Mobile
Mermaid Fishing is a real-time multiplayer game — lag spikes can cause your aimed shots to miss moving targets that have already shifted position by the time your bullet registers. If you are playing on mobile data in Dhaka or Chittagong during peak evening hours (8 PM to 11 PM BST), consider switching to a 5G connection or home Wi-Fi. A missed shot on a Legend-tier target during a narrow spawn window is a costly latency tax.
Learn the Boss Spawn Cycle
The Mermaid Queen spawns on a roughly 8-to-12-minute cycle from the last defeat. Track the time when she is defeated and start preparing your cannon loadout at the 7-minute mark — switch to your highest tier cannon and ensure you have a Golden Bullet ready. The first 10 seconds after the Queen spawns are her most vulnerable window before she activates her shield phase.
Use Auto-Fire Strategically, Not Constantly
The tap-and-hold auto-fire feature on mobile is tempting to leave running indefinitely, but it drains your balance rapidly if aimed at empty water or fast-moving common fish that dodge out of the firing line. Use auto-fire only when a large, slow target — the Crystal Whale, Coral Guardian, or a stationary Treasure Chest — is locked firmly in your cannon's path. For everything else, manual targeted shots preserve your bullet budget far better.
