Relax Fishing puts you in control of an underwater shooting gallery where every catch pays out real BDT. Aim for the big sea creatures, trigger special weapons, and land jackpot fish for the highest multipliers — all playable in seconds via bKash or Nagad at tk688.
Relax Fishing is one of the most engaging titles in the tk688 game library — a real-money fishing arcade game that blends fast-twitch shooting mechanics with the strategic depth of choosing the right weapon for each target. Unlike traditional slot games where you spin and wait, Relax Fishing puts you in active control: you aim your cannon, select your firepower, and shoot at fish swimming across a richly animated underwater scene. Every fish you catch pays out an instant BDT multiplier based on that fish's value — and the bigger and rarer the creature, the larger the reward.
The game supports one to six players in a shared room simultaneously, creating a social dimension that is unusual in online casino gaming. Bangladeshi players from Dhaka, Chittagong, and Sylhet can find themselves in the same room, each controlling their own cannon and chasing the same rare boss fish. There is a friendly competitive element — if another player catches a high-value fish just before your shot lands, you miss out — but the game moves quickly enough that opportunities for big catches come around regularly.
The core loop of Relax Fishing is straightforward. Each bullet you fire costs a set amount of BDT — your "bet per bullet". You select your cannon's firepower from a range of available tiers, which determines both the cost per shot and the multiplied payout when you catch a fish. A small fish caught with a ৳5 bullet pays out a small BDT amount; the same small fish caught with a ৳50 bullet pays proportionally more. The exchange rate between bullet cost and payout multiplier is fixed per fish type, so scaling your firepower up or down does not change your expected return — it changes your risk and reward profile per individual shot.
What keeps Relax Fishing interesting over extended sessions is the variety of fish types, the rotating roster of special weapons, and the periodic appearance of boss creatures. Standard fish swim in steady patterns and are relatively easy to catch. Mid-tier fish — sharks, manta rays, electric eels — move faster and require more bullets, but their payout multipliers justify the ammo cost. Boss fish appear infrequently but carry multipliers that can reach 800× your bullet value, creating moments of high excitement that break up the steadier rhythm of regular catches.
Relax Fishing at tk688 features several special weapon types that activate periodically and can dramatically change the pace of a round. The Railgun fires a piercing beam that passes through multiple fish in a straight line, catching several creatures in a single shot. The Torpedo targets a specific fish automatically and tracks it until impact — useful for faster-moving mid-tier targets that are difficult to lead manually. The Drill Cannon creates a spinning drill that sweeps through a cluster of fish, ideal for dense schools of standard fish where per-fish value is low but volume of catches is high. Each special weapon costs more BDT per activation than a standard bullet but offers a significantly better expected catch rate against the right target types.
The Freezing Shell is arguably the most strategically useful weapon in the game. When activated, it freezes all fish currently on screen for approximately three seconds — creating a brief window where you can aim carefully at high-value targets without them swimming out of frame. Experienced tk688 players learn to save Freezing Shells for moments when a mid-tier or boss fish is on screen, maximising the value of the freeze window rather than using it on schools of common small fish.
Fishing is deeply embedded in Bangladeshi culture — Bangladesh is one of the world's largest fish-producing nations, and the imagery of rivers, haor wetlands, the Bay of Bengal, and abundant sea life resonates culturally in a way that is immediate and familiar. Relax Fishing taps into this naturally, presenting an underwater world full of creatures that feel vibrant and engaging rather than generic. For players in Khulna, Barisal, and Cox's Bazar — coastal and riverine communities with deep fishing traditions — there is an additional layer of familiarity to the game's visual language.
Beyond the cultural resonance, the game's mechanics suit the Bangladeshi playing style. Sessions can be as short as five minutes or as long as an hour depending on how you pace your bullet usage. The minimum bullet cost at tk688 is ৳1, meaning a player with a modest ৳300 deposit can explore the game for a meaningful amount of time before needing to reload. Instant deposits via bKash and Nagad mean that topping up your balance mid-session takes under thirty seconds — there is no friction between wanting to continue and actually continuing.
Relax Fishing carries a certified RTP of 97.0%, one of the highest in the tk688 fishing game category. This figure represents the theoretical long-run return across all players and all fish types — individual session outcomes vary considerably depending on which fish you target, which weapons you use, and how often boss creatures appear during your session. tk688 publishes RTP data for all game titles, and Relax Fishing's 97.0% figure is verified by an independent testing laboratory. The game uses a certified Random Number Generator to determine fish movement patterns, spawn rates, and the catch outcomes of borderline shots where a fish is partially in the hit zone.
Every fish in Relax Fishing carries a fixed multiplier applied to your bullet cost when caught. Here is the full target roster available at tk688.
| Fish / Target | Payout Multiplier | Difficulty | Notes |
|---|---|---|---|
| Small Tropical Fish | 2× – 5× | Easy | Slow-moving, common spawn. Good for warming up and testing bullet cost. |
| Clownfish School | 3× – 8× | Easy | Appears in groups. Drill Cannon is effective for multi-catch efficiency. |
| Sea Turtle | 10× – 20× | Medium | Moves steadily but requires sustained fire. Good value for mid-range bullets. |
| Electric Eel | 15× – 30× | Medium | Erratic movement. Railgun or Torpedo recommended for reliable catches. |
| Hammerhead Shark | 30× – 60× | Medium | Fast horizontal swimmer. High bullet cost justified by strong multiplier. |
| Giant Manta Ray | 50× – 100× | Hard | Large hitbox but fast. Freezing Shell is highly effective here. |
| Swordfish | 80× – 150× | Hard | Linear fast movement. Lead the target — Torpedo auto-tracks reliably. |
| Golden Crab | 100× – 200× | Hard | Rare spawn. Appears briefly — prioritise immediately when it enters frame. |
| Colossal Octopus (Boss) | 200× – 500× | Boss | Absorbs many bullets. Coordinate with room players for fastest kill. |
| Dragon King (Mega Boss) | 500× – 800× | Boss | Rarest spawn in Relax Fishing. Maximum payout potential at tk688. |
Choose the right tool for each target — special weapons can dramatically improve your catch rate and BDT payout per session.
Fires a high-energy beam that pierces through multiple fish in a straight line. Best used when a row of mid-tier fish align horizontally — one shot can catch three or four creatures simultaneously, multiplying your BDT return per bullet spend.
Auto-tracks a chosen fish until impact. Ideal for fast-moving targets like the Electric Eel or Swordfish that are difficult to lead manually. The tracking cost is slightly higher than a standard bullet but the hit guarantee makes it cost-effective on high-value fish.
Releases a spinning drill that sweeps through a zone of fish, catching multiple targets in a wide arc. Highly effective against dense schools of small tropical fish and clownfish groups. Lower per-fish value but outstanding catch volume during school spawns.
Freezes all fish on screen for approximately three seconds. Creates a targeting window for high-value fish that would otherwise escape frame. Save this for moments when the Golden Crab, Manta Ray, or a Boss creature is visible — the time window is precious.
Deploys an electrified net that stuns all fish within a circular radius. Stunned fish have increased catch probability for the next five shots. Effective when a medium-density mixed group is on screen — combines well with a follow-up Drill Cannon sweep.
A single high-cost explosive that deals massive damage to a targeted area. The most effective weapon against Boss-tier creatures like the Colossal Octopus and Dragon King. In a multiplayer room, coordinating Mega Bombs with other players dramatically shortens Boss kill time.
Performance in Relax Fishing is influenced by a mix of skill, timing, and resource management. Here is how the key player attributes contribute to session outcomes.
These ratings reflect the relative contribution of each skill to positive long-run outcomes in Relax Fishing sessions at tk688. Target prioritisation is rated highest because directing your fire at mid-tier and high-tier fish rather than chasing small common fish is the single biggest driver of session efficiency.
Practical guidance to help you fish smarter and manage your BDT balance more effectively during Relax Fishing sessions.
The most common mistake new Relax Fishing players make at tk688 is firing continuously at small tropical fish out of habit. Small fish provide very low BDT returns relative to bullet cost. Whenever a Sea Turtle, Electric Eel, or Shark appears, shift your focus immediately. The opportunity cost of burning bullets on small fish while a mid-tier target swims past is the primary driver of negative session outcomes for beginners.
Decide in advance how many BDT worth of bullets you are willing to spend in one session and stick to it. For example, if you deposit ৳1,000 via Nagad, allocate ৳700 as your shooting budget and keep ৳300 as a floor you will not cross. When your bullet spend reaches ৳700, stop — regardless of how the session is going. This prevents the common pattern of chasing losses by escalating bullet cost in the final minutes of a session.
The Freezing Shell has a cooldown after each use, so you cannot deploy it continuously. Many players waste their Freeze on crowded screens full of small fish when the optimal play is to wait. If you have a Freezing Shell available and the Golden Crab, Giant Manta Ray, or a Boss creature enters the screen, that is your trigger. Three seconds of frozen high-value targets can generate more BDT than twenty standard shots at small fish.
When the Colossal Octopus or Dragon King appears in a multiplayer room at tk688, the Boss has a health pool that requires sustained damage to deplete before it exits the frame. A single player firing alone may not kill it in time. If you can see other players in the room focusing the same Boss, concentrate your fire on it too — the shared effort benefits everyone equally, and the player who lands the killing shot earns the full 500×–800× multiplier. Coordination is key.
After a big Boss catch paying out several thousand BDT, the temptation is to immediately upgrade your bullet cost to maximum and "press your advantage." Resist this. Your expected return per bullet in Relax Fishing is determined by RTP and fish value, not by recent history. Keep your bullet cost at a level where you can sustain at least 200 shots from your current balance — this ensures you have enough runway for Boss creatures to appear and be caught.
tk688 periodically runs promotions specifically for fishing game categories — these may include rebate on losses, double multiplier events on Boss catches, or free bullet credits for qualifying deposits. Promotions are often timed around peak Bangladesh entertainment periods like BPL cricket season, Eid al-Fitr, Eid al-Adha, and Pohela Boishakh.

Relax Fishing is a blend of both. Fish movement patterns and spawn rates are determined by a certified RNG, so you cannot predict exactly when high-value fish or Boss creatures will appear. However, your choices — which fish to target, which weapon to use, how to allocate your bullet budget — have a meaningful impact on your expected session return. Players who consistently prioritise mid-tier and high-tier targets outperform players who fire indiscriminately, even over a large number of sessions.
The minimum deposit at tk688 is ৳200, which can be made instantly via bKash, Nagad, Rocket, or Upay. With a ৳200 deposit and a ৳1 bullet cost, you have 200 shots to start with — more than enough to experience several fish types and potentially trigger a special weapon event. As you build familiarity with the game, you can scale your bullet cost to match your balance and risk preference.
Yes. Relax Fishing is fully optimised for mobile play on Android and iOS devices. The game runs in any modern mobile browser without requiring an app download. Touch controls are native and responsive — tapping to aim and fire feels natural on a smartphone screen. Players in Dhaka, Chittagong, Sylhet, and across Bangladesh report smooth, lag-free gameplay on standard 4G mobile connections.
When you launch Relax Fishing at tk688, you can choose between a solo room and a shared room that accommodates up to six players. In a shared room, each player controls their own cannon independently — your bullet cost and payout are separate from other players. The main shared element is the Boss fish health pool: all players' shots contribute to depleting it, and whichever player fires the killing shot earns the full Boss multiplier payout. This creates a cooperative-competitive dynamic that makes Boss spawns particularly exciting in full rooms.
The Dragon King is the rarest spawn in Relax Fishing, appearing approximately once every 15–30 minutes of active play based on average session data. Its appearance is determined by the game's RNG and cannot be predicted or influenced by player behaviour. When it does appear, it moves slowly but absorbs a large number of bullets before being caught — coordinating with other room players significantly improves your chances of landing the killing shot before it exits the screen.
