Here’s a simple way to make a video game case opening system in Roblox, with a style that can fit a Welcome to Bloxburg-inspired UI. One good reference point is a Roblox tutorial for a case opening system, and another shows how creators build Bloxburg-like UI elements in Studio.

Basic idea

A case opening system usually has:

  • A button to open a case.
  • A scrolling row of possible rewards.
  • A random selection that stops on one item.
  • A reward handler that gives the player the chosen item.

The case-opening pattern is commonly built with a weighted random list and a visible indicator line that picks the final result.

How to build it

  1. Create the UI.
    Make a main frame, an opening button, and a horizontal reward strip. The Bloxburg UI tutorial shows that creators often use clean rounded panels and polished menu styling for that look.
  1. Add your item pool.
    Put each possible reward into a table with a rarity or weight. A weight system is useful because it makes rare items less likely than common ones.
  1. Spin the row.
    When the player clicks open, animate the reward strip moving left while a fixed indicator stays in place. The closest item to that indicator becomes the final reward.
  1. Choose the winner on the server.
    Do the random selection on the server, not only on the client, so it is harder to exploit.
  1. Give the reward.
    After selection, award the item, currency, or cosmetic and update the player’s inventory.

Bloxburg-style design

If you want the case opener to feel like Welcome to Bloxburg, aim for:

  • Soft colors.
  • Rounded corners.
  • Simple icons.
  • Clean spacing.
  • Minimal, polished text.

That style is closer to a life-sim menu than a flashy loot box screen, which matches the aesthetic shown in Bloxburg UI tutorials and gameplay examples.

Example flow

A player clicks Open Case :

  • The UI slides into view.
  • A strip of rewards begins scrolling.
  • The motion slows.
  • The indicator lands on one reward.
  • The game shows the item name and gives it to the player.

That same basic structure is the standard approach in Roblox case-opening systems.

Important note

If by “Roblox Welcome to Bloxburg” you meant making a Bloxburg-style game case or menu, the safest interpretation is to copy the style and not the exact game assets or branding. The public references show Bloxburg as a life- simulation experience, so a similar UI should stay original in assets and naming.

TL;DR

Build a clean UI, use a weighted reward table, animate a scrolling strip, pick the final reward on the server, and keep the design soft and minimal for a Bloxburg feel.
