Head to pub 504 Login and sign in. If you're new, registration takes less than two minutes. Remember — you must be 21 years or older to play.
Deposit via GCash, PayMaya, or bank transfer (BPI, BDO, Metrobank). Minimum deposit starts at ₱100 — enough to get a solid session going.
Choose how much each bullet costs — from ₱1 for casual play up to higher stakes for experienced hunters. Your payout multiplies based on the bullet value when you catch a creature.
Tap or click to fire at sea creatures swimming across the screen. When you land the killing shot, the prize is instantly credited to your pub 504 balance.
Catching the Giant Octopus activates a bonus round where all creatures on screen multiply in value. These moments can turn a modest session into a massive payday.

Cash out anytime via GCash or PayMaya. Most withdrawals at pub 504 process within minutes — your winnings go straight to your e-wallet, no hassle.
Set a session budget before you start. pub 504 offers self-limit tools in your account settings. Gambling is addictive — always know when to stop.
Experienced pub 504 players from Manila to Cebu share these strategies to help you get more out of every session.
Small fish give low returns; boss creatures take too many bullets. Golden Crabs and Octopuses offer the best balance of hit rate and payout — focus your firepower there for consistent returns.
Mermaid Fishing is multiplayer — up to 4 players share the same screen. When a boss like the Shark or Sea Dragon appears, coordinating fire with other players increases the chance of landing the final shot.
Don't blow your entire balance chasing the Mermaid Queen in the first five minutes. Start with lower bullet values, build your balance, then increase stakes when a boss event triggers.
More players online means more bullets hitting boss creatures — which means boss events resolve faster and the next one spawns sooner. Peak hours in the Philippines are typically 8 PM to midnight.
