In Cage Fishing on Roblox, the lucky box is usually opened by getting close to it and interacting with it when the prompt appears. If it is the same “lucky chest/box” shown in recent guides, you may need to reach the correct area first, then press the interaction key or tap the on-screen button to open it.

How to try it

  1. Go to the lucky box location in the game.
  2. Stand right next to the box.
  3. Look for an Open or Interact prompt.
  4. Press the shown key on PC, or tap the prompt on mobile.

If it will not open

  • Make sure the box is not part of a different feature, like an enchant chest or treasure chest area.
  • Try rejoining the server, because some Roblox game objects only work after they load properly.
  • Check whether the box needs a certain progress level, item, or currency before it becomes usable.

What recent posts suggest

Recent public posts around Cage Fishing mention a “lucky chest” and “lucky box” tied to enchant or random reward systems, which suggests the box may be opened through a normal in-game interact action rather than a special menu. A separate post about treasure chests in a Roblox fishing game also shows that positioning and interaction can matter if the chest is awkward to reach.

TL;DR: walk up to the lucky box, look for the interact prompt, and open it with the displayed key or tap action.
