The Big One Dev Log: Why Sell All Shows Both Fish Count and Gold
When you return from fishing, if you have five fish in your keepnet, should the Sell All confirmation window also show five? If there are fish you locked to keep, it is more natural for the two numbers to differ. From our perspective developing The Big One, this post discusses the subtle information design right before you tap the sell button.
This article is a development log based on the development code and Korean text verified on September 21, 2026. It is not an announcement that a new feature has been released to every store version today. The screen layout or navigation flow may differ depending on the version actually installed.
Total Keepnet Fish and Sell Targets Are Distinct Lists
In the currently verified fish merchant screen, the system first reads the fish in your keepnet and counts only unlocked fish as sellable targets. The estimated gold also sums up the prices of those same targets. This structure ensures that quantity and currency are not calculated using different standards.
For example, if you have five fish in your keepnet and locked two of them, the sell target is three. These are hypothetical numbers used for illustration and do not represent the game's default keepnet capacity or actual play records. Even if the number in the confirmation window is smaller than your total keepnet count, there is no need to suspect something went missing.
The Confirmation Window Previews the Next State
When you tap Sell All, it displays both the number of sellable fish and the gold you will receive, asking for your confirmation. If there are no sellable fish, the batch sell flow will not execute. Reading these two pieces of information makes it easier to judge what will actually leave your keepnet, rather than relying solely on the button label.
The actual sell logic in the development code also re-checks lock status. In batch selling, it retains locked fish and adds only the price of the sell targets to your gold. In individual sales as well, it checks that locked fish cannot be sold. The key is that on-screen guidance and sale processing follow the exact same rules.
Distinguishing Fishpedia Records from Keepnet Fish
The collection data in your Fishpedia and the fish currently stored in your keepnet serve different purposes. What you decide on the merchant screen is which individual fish to keep and which to sell right now. Rather than tapping Sell All simply remembering fish names seen in the Fishpedia, it is better to double-check the lock markers in your keepnet.
Lock the fish you want to keep first, then check the sellable count and estimated amount on the merchant screen. If your goal for that fishing trip was checking records, take a look at the Fishpedia as well. Locking is a way to record your intent to keep something on screen, preserved even when you return later.
Developer Questions When Reviewing a Small Confirmation Window
When looking at this screen, I consider cases with no sell targets, partially locked fish, and completely locked fish as distinct scenarios. Even when pressing the same button, the fish that should remain are different. These are checklist scenarios to verify, and this post does not claim that device-specific testing has been completed.
Aligning the criteria between quantity and currency comes before stuffing the confirmation window with lengthy explanations. The takeaway from this post is simple: the next time you tap Sell All, check whether the total keepnet count and the sellable count match, and if they differ, see which fish you are keeping.
The Big One is a fishing RPG that connects casting, bites, hooking, reeling, and fish collecting. You can check the currently available version in the stores below. We will continue refining minor text and status indicators to ensure even sorting your catch after fishing feels seamless.
