Overview
- The latest guides published July 23, 2026 list two working codes: FREESTARS, which grants two Stars, and MERGE, which gives 1,000 Cash.
- To redeem codes players open Merge a Black Hole on Roblox, finish the brief tutorial if needed, tap the Codes icon or open the shop, enter the code, and press Redeem.
- Cash is used to unlock and upgrade black holes while Stars buy spins and abilities such as Hole Surge or multipliers, so codes accelerate early progression and raid readiness.
- Reporting across the guides says developers tied to XAF Games typically post codes in the game's official Discord and its Roblox group, and one source notes a reported Sunday update cadence that has limited independent corroboration.
- Because codes are short lived, players are advised to join the Merge a Black Hole Discord or XAF Games Roblox group and bookmark code pages to claim drops quickly when they appear.
