24 Hours Overnight is a Roblox survival game where you and your friends barricade a store or warehouse against employees and monsters for a full in-game day. Codes hand out free gems, the currency used to unlock survival classes and playstyles.

Working 24 Hours Overnight codes

Two codes are redeemable right now for free gems.

  • NIGHT — 10 gems
  • PRISON — 20 gems

Spend the gems on classes that fit how you want to play, whether that means slipping past guards unnoticed or gearing up to fight off whatever breaks into your base at night.


How to redeem codes in 24 Hours Overnight

Codes are entered from inside the game rather than through a separate website, so you need to load into a server first.

Launch 24 Hours Overnight on Roblox and let the server finish loading into the main game screen.
Click the Shop button on the side of the screen.
Select the Codes button inside the Shop menu.
Type or paste a code into the text box exactly as it appears, since codes are case-sensitive.
Press Redeem to claim the gems.

A successful redemption adds the listed gems to your total immediately, visible in the Shop menu. If the code box rejects an entry, double-check for extra spaces or mismatched capitalization before trying again.


Expired 24 Hours Overnight codes

The following code no longer works and will return an error if entered.

  • REWORK — previously 20 gems

Where new codes get announced

New codes tend to appear around game updates and special events rather than on a fixed schedule. The developer, A-1 Productions, posts announcements through the game’s official channels, including the 24 Hours Overnight Discord server and the A-1 Productions Roblox group.

Bookmark this list of codes and check back periodically, since gems are otherwise slow to accumulate through normal scavenging and unlocking a new class early can make the difference between surviving the night and getting caught out in the open.
