Build a Base and Steal Codes

The code system and its history

Build a Base and Steal launched without any code system. Redemption arrived with the mid-July 2026 [UPD] patch - the fan wiki's dated history is explicit that pre-mid-July strings return an invalid-code message because nothing existed to redeem them.

Every documented reward since has kept the same shape: a temporary Luck boost. Codes improve pet-roll odds for a short window, which makes them session openers rather than permanent upgrades.

Strings retire at the biweekly Saturday event rhythm, so the working list on this page is a dated snapshot, not a standing truth. The check dates below say exactly how old each claim is.

Redemption, both ways it has been described

The two main trackers describe the entry point differently, and both descriptions are preserved here. GameRant (updated August 16, 2026): launch the game, tap the Shop icon on the left side of the screen, scroll to the Redeem section, paste the code into the 'Enter Code...' box, and hit Redeem.

build-a-base-and-steals.wiki (verified July 31, 2026): after your base loads, go to the right-side Shop menu behind the NPC counter, find the Codes textbox on the right edge of the Shop panel, paste the code exactly, and confirm the reward before closing the dialog.

The layouts may have moved between the two checks, so the practical instruction is: open the Shop panel - from either side - and look for the Codes textbox in or beside it. Codes are case-sensitive, so paste rather than retype.

If a code fails, the fan wiki's troubleshooting applies: you may be on a pre-[UPD] server (server-hop and retry), or the Shop panel cached after a hop (log out, restart the client, re-enter).

Where new codes appear

The July-August 2026 record shows codes following two triggers: milestones (WeHit30K and Happy30K landed within days of the 30K marker and the July 21 35M-visits signal) and updates (UPDATE followed the mid-August patch window; VOLCANOO matched the Volcano event theme and verified July 28).

GameRant directs players to the game's official Discord server for fresh strings, and MrGuider lists the invite as discord.com/invite/TBaqmFBFmr. Creator posts after events and milestones are the reliable first alert.

Watch for copy-strings: Happy30KCopy and WeHit30KCopy are documented broken variants that reject with an invalid-code message - always use the exact strings above.

How this list is maintained

A code joins the working list only with a dated public source: a tracker's verification, a fan wiki's in-game redemption log, or a creator post. Conflicting details are shown both ways (WeHit30K's window is 10 minutes per GameRant, 5-10 per the fan wiki's log).

When you redeem a code listed here and it fails after the troubleshooting steps, treat that as a personal freshness check - the biweekly event cadence means the list can age by one event weekend. The official Discord and the official Roblox page remain the authoritative sources.
