89db Mermaid Fishing — Hunt for the Jackpot in the Deep Sea with Your Cannon
Mermaid Fishing is a game where sharp eyes, smart thinking, and the right cannon level all come together. Shoot at mermaids, sharks, jellyfish, and giant boss fish in a colourful underwater world, build your points, and win big rewards.
Core Rules of Fishing Games — From Cannon to Target
The basic structure of Mermaid Fishing is the same as other arcade shooting games — you fire bullets from a cannon to catch various creatures moving underwater. Each bullet has a fixed cost that depends on the cannon level. The higher the level, the more each shot costs — and the bigger the reward when you make a kill.
Small, medium, and large creatures move across the screen at the same time. Small fish give fewer points but are easy to hit, so they use fewer bullets. Large creatures, especially golden sharks or giant mermaid characters, can absorb many shots but give big rewards when caught.
Special boss targets appear on screen from time to time — they are far stronger than regular creatures and will escape if you do not focus on them consistently. Killing a boss can activate a multiplier reward or a special bonus round.
Regular Fish
Plentiful and easy to catch — useful for building up points steadily.
Mid-Tier Targets
Sharks, rays — take multiple shots but give higher rewards.
Boss Characters
Mermaid Queen or giant octopus — defeat them for a jackpot reward.
Special Weapons
Laser or explosive bullets — once activated, they can take out many creatures at once.
Unique Features of Mermaid Fishing
The most distinctive aspect of Mermaid Fishing is its underwater theme — coral reefs, flowing water, and mermaid characters of various colours drift across the screen. Each mermaid character has its own point value; the golden mermaid is the most valuable and appears on screen for only a short time.
The game has a special "whirlpool" feature — when a specific trigger is activated, a water vortex fills the entire screen and at that moment the point value of all creatures increases several times over. Using a high-level cannon at the right time during this feature can yield large rewards.
There is also a "Mermaid Treasure" bonus chest in the game — shooting the floating boxes that appear in certain corners of the screen reveals random rewards, which can include cash, free shots, and multiplier boosts.
Choose Your Cannon Level to Match Your Budget
Choosing the cannon level is the most important decision in Mermaid Fishing. Each level has a different cost per shot — costs generally increase from level 1 up to the maximum level. A higher-level cannon deals more damage, which improves your chances of killing boss creatures, but each miss costs more money.
A simple rule: divide your total session budget into at least 50–60 shots and set your cannon level accordingly. If your session budget is ৳500, it is sensible to start at a level where each shot costs around ৳8–10. This lets you keep your balance ticking over by catching smaller fish while still having firepower ready when a boss arrives.
Jumping straight to a high level drains your balance quickly. Many players start at a low level to build up their balance and then move to a higher level — this is an effective approach. At 89db, 89db VIP members receive weekly cashback, which makes it easier to start fresh in the next session.
Solo Play vs Shared Room — Which is Right for You?
Solo Room
In a solo room, you play alone. There is no risk of another player shooting your target and taking the reward. You can wait patiently for a boss to appear and focus fully on it. Solo rooms are good for new players — you can learn at your own pace.
Shared Room
In a shared room, multiple players fire at the same screen at the same time. Boss creatures move around and whoever lands the final shot takes the reward. The competitive element is stronger here — experienced players tend to understand boss-hunting strategy better in shared rooms.
One thing to keep in mind in a shared room: if you deal heavy damage to a large boss fish but someone else fires the last shot, the reward goes to them. So when a boss appears in a shared room, you need to shoot quickly and consistently. Understanding the feel of each room and adjusting your strategy accordingly is important.
Strategy for Target Selection and Timing
Use the Screen Corners
Creatures slow down as they move into or out of the corners of the screen. Shooting at that moment gives you a better chance of landing a hit.
Prepare Before a Boss Arrives
Before a boss creature enters the screen, there is usually a distinct sound or flash of light. Use that moment to adjust your cannon level.
Focus on One Target
Splitting shots between two targets at once leaves both half-dead. It is more effective to finish one creature completely before moving on to the next.
Watch Your Balance
Stop if you lose more than 20% of your total balance in one stretch. If you are on a winning run, raise your cannon level gradually.
Save Special Weapons for Boss Targets
Do not use laser or explosive bullets casually — save them for boss targets to give yourself the best chance of a big reward.
Take Breaks During Your Session
Playing for a long stretch without a break reduces focus and leads to wasted shots on the wrong targets. Take a short break every 30–40 minutes.
Common Mistakes to Avoid
The most frequent mistake new players make in Mermaid Fishing is selecting the maximum cannon level right from the start. At a high level, the cost per shot is so high that recouping it by catching small fish is nearly impossible. The entire session budget can run out within a few minutes.
Another familiar mistake is raising the cannon level to "chase losses". This approach makes losses mount even faster. Instead, set a fixed session budget and stop for the day once it is gone.
Many players dump all their bullets into a boss target the moment one appears, but if the boss escapes they have almost nothing left for the rest of the session. Spending no more than 30–40% of your total budget on a single boss target is the wiser approach.

Avoid
- Using the maximum cannon level in your very first session
- Raising the level after a loss to "win it back"
- Spending all your bullets on a single boss
- Splitting your focus across multiple targets at once
- Continuing to play after your session budget is gone
Mermaid Fishing vs Slot Games — Key Differences
The biggest difference between Mermaid Fishing and slot games is the degree of control the player has. In slot games, pressing the spin button produces a result that is entirely random — the player makes no decisions. In a fishing game, which target you shoot, when you shoot, and which cannon level you use are all decisions that remain in your hands.
Slots have a fixed RTP percentage that is already programmed in. In a fishing game, the reward structure depends on the type of creature and the timing of the kill — strategy and observation play at least some role in the outcome.
Like slots, fishing games use a random number generator (RNG), but your active involvement is greater. Many players who want a more hands-on experience than slots offer find Mermaid Fishing more enjoyable.
