Mega Fishing is not your average fishing game. It's a full-on underwater arcade experience where you aim, fire, and collect — targeting everything from common reef fish to colossal sea monsters that carry multipliers up to 800×. On 678bet, it's one of the most-played titles on the platform, and once you understand how the cannon system and special creatures work, it's easy to see why.
Most online casino games are passive — you spin, you wait, you collect. Mega Fishing flips that entirely. You're actively aiming a cannon at moving targets, choosing which creatures to prioritise, managing your ammo cost per shot, and deciding when to switch to special weapons. It's the kind of game that keeps your hands busy and your brain engaged, which is a big part of why it's so popular among 678bet players who want something more interactive than a standard slot.
The game runs on a shared multiplayer table where up to four players fire simultaneously at the same underwater scene. Each player controls their own cannon independently, so there's no interference between players — you're competing for the same fish but your shots and winnings are entirely separate. The visual design is vivid and detailed, with dozens of different sea creatures moving across the screen at varying speeds and carrying different prize values.
What separates Mega Fishing from older fishing arcade games is the depth of its special mechanics. Beyond the standard cannon, there are torpedo weapons, drill shots, and a Mega Octopus bonus event that can award prizes to every player at the table simultaneously. These features turn individual sessions into genuinely varied experiences rather than repetitive shooting.
Six systems that define how you play and win on 678bet.
You control a cannon mounted at the bottom of the screen. Tap or click to aim and fire at any creature on screen. Each shot costs a set amount based on your current cannon power level — higher power means more damage per shot and larger prizes when a creature is caught, but also higher cost per bullet. Finding the right power level for the creatures currently on screen is a key part of playing efficiently on 678bet.
The torpedo is a special weapon that travels in a straight line and deals heavy damage to the first creature it hits. It's most effective against large, slow-moving targets like the Giant Crocodile or Mega Octopus. Torpedoes cost more per use than standard shots but have a significantly higher damage-to-cost ratio against high-value targets, making them worth saving for the right moment.
The drill shot spins through the water and can hit multiple creatures in its path before stopping. It's the best weapon for clearing groups of smaller fish that are clustered together, since a single drill shot can catch two or three creatures simultaneously. On 678bet, experienced players often switch to drill shots when a school of medium-value fish appears, then return to standard cannon fire for individual high-value targets.
The Mega Octopus is a special event creature that appears periodically and triggers a table-wide bonus when defeated. All four players at the table contribute shots to bring it down, and when it's caught, every player receives a prize based on their individual contribution. The Mega Octopus carries one of the highest multipliers in the game and is the moment most 678bet players are waiting for during a session.
Certain boss-tier creatures in Mega Fishing are designated as immortal — they cannot be permanently killed but award prizes each time they take enough damage. These creatures cycle through the screen repeatedly, giving every player at the 678bet table multiple opportunities to score from the same target. The prize per hit scales with the damage dealt, so higher cannon power pays off significantly against immortal bosses.
Mega Fishing is fully optimised for the 678bet mobile app on Android and iOS. The aiming and firing controls are designed for touchscreen use — tap to aim, hold to lock, release to fire. The game loads quickly on mobile data connections common across Bangladesh, and the multiplayer table syncs in real time with minimal lag. You can play comfortably on a mid-range Android phone without any performance issues.

Table-wide event creature. All players contribute — all players share the reward.
Rare surface appearance. High health pool — save your torpedo for this one.

Mega Fishing rewards players who think about their shots rather than just firing continuously at whatever moves. The core decision you're making on every shot is whether the expected prize from a creature justifies the ammo cost at your current cannon power level. A small reef fish caught with a ৳50 cannon shot is a terrible trade — the prize won't cover the cost. The same shot aimed at a Giant Crocodile or Sea Dragon is a completely different calculation.
The most efficient approach for new 678bet players is to start at a low cannon power — ৳5 to ৳10 per shot — and focus on medium-value creatures like the Giant Crab and Hammerhead Shark. These targets have enough health to require several shots but carry prizes that comfortably exceed the ammo cost when caught. As you get comfortable with the aiming mechanics and creature movement patterns, you can gradually increase cannon power and start targeting higher-value creatures.
Special weapons are where Mega Fishing gets genuinely strategic. The torpedo is best saved for slow, high-health targets — the Giant Crocodile and Mega Octopus are the prime candidates. Firing a torpedo at a small fish is wasteful; firing it at a 300× crocodile that's moving slowly across the screen is exactly the right call. The drill shot, on the other hand, is most valuable when a school of medium-value fish clusters together. A single drill shot through a tight group can catch two or three creatures simultaneously, effectively multiplying your return on that single weapon use.
The Mega Octopus bonus event is the highlight of any Mega Fishing session on 678bet. When it appears, every player at the table should redirect their fire immediately. The octopus has a large health pool and requires coordinated shooting from all four players to defeat before it leaves the screen. The prize is distributed to all players based on their contribution, so even if you join the fight late, getting shots in before it disappears is worth doing. The 100× to 200× multiplier on the Mega Octopus means a ৳50 cannon shot contributing to its defeat can return ৳5,000 to ৳10,000 from a single event.
Immortal boss creatures are a consistent source of income during a session. Because they cycle through the screen repeatedly and award prizes each time they take enough damage, they're reliable targets that don't require the luck of a rare creature appearing. The Immortal Whale, for example, awards 50× per damage threshold hit. At ৳10 per shot, that's ৳500 per threshold — and a patient player who focuses on the whale across multiple passes can accumulate significant returns without ever needing a rare boss to appear.
One practical advantage of playing Mega Fishing on 678bet specifically is the withdrawal speed. When you've had a strong session — particularly after a Mega Octopus event or a Sea Dragon catch — bKash and Nagad withdrawals typically process within ten minutes. That immediacy is important for players who want to cash out after a big win rather than leaving funds sitting in their account. 678bet has built a strong reputation among Bangladeshi players for fast, reliable payouts, and Mega Fishing players benefit from that directly.
Overall, Mega Fishing is one of the most engaging games available on 678bet because it combines genuine skill — in aiming, weapon selection, and target prioritisation — with the excitement of high-multiplier prizes. It's not a game where you sit back and watch reels spin. You're actively involved in every outcome, which makes wins feel earned and sessions feel genuinely entertaining from start to finish.
