Coding Simulator 2 is a Roblox business simulator where you build a tech empire from the ground up. Free codes from developer RoDark Studios hand you Diamonds, Potions, and currency boosts that speed up everything from hiring developers to unlocking new companies. However, codes disappear without warning, so redeeming them the moment you find them is always the smarter move. Here are all the confirmed working Coding Simulator 2 codes for May 2026.
All Active Coding Simulator 2 Codes (May 2026)
| Code | Reward |
| 1000diamonds (NEW) | 1,000 Diamonds |
| 500kvisits (NEW) | Cash Potion 3, Diamonds Potion 3, NFT Luck Potion 3 & Mining Luck Potion 3 |
Important: Codes in Coding Simulator 2 are case-sensitive. Type them exactly as shown above or copy-paste them directly. Also, you must be a member of the RoDark Studios Roblox Group before any code will work.
What Do the Rewards Actually Do?
Each reward type in Coding Simulator 2 serves a specific purpose in growing your tech business. Here is what you get from the current codes:
- Diamonds – The premium in-game currency used to unlock upgrades, purchases, and progression boosts that are harder to earn through regular gameplay. The 1000diamonds code gives you 1,000 instantly.
- Cash Potion 3 – Temporarily boosts your cash earnings by 30% for 30 minutes, letting you stack money faster during active sessions.
- Diamonds Potion 3 – Increases your Diamond gain rate by 30% for 30 minutes, helping you earn the premium currency faster without spending real Robux.
- NFT Luck Potion 3 – Boosts your NFT Luck by 30% for 30 minutes, improving your chances of landing high-value NFT multipliers that accelerate your cash flow.
- Mining Luck Potion 3 – Increases Mining Luck by 30% for 30 minutes, giving you a better shot at collecting the meteors needed to craft Quantum Artifacts.
If you redeem both active codes together, you walk away with a solid Diamond reserve and a full set of 30-minute boosts covering every major resource in the game.
Are There Any Expired Codes?
As of May 1, 2026, there are no expired codes in Coding Simulator 2. Everything on the active list above is still redeemable. However, codes can stop working at any point without advance notice from the developer, so act quickly.
How to Redeem Coding Simulator 2 Codes
Redeeming codes in Coding Simulator 2 is slightly different from most Roblox games since it requires a group membership and finding a specific NPC in-game. Follow these steps carefully:
- Join the RoDark Studios Roblox Group before doing anything else. Codes will not work without group membership, so this step is mandatory.
- Launch Coding Simulator 2 on the Roblox platform.
- Hit the green Buy button to get teleported to the shop area.
- Find the Verify NPC located to the left of the entrance to the Hardware shop.
- Speak to the Verify NPC and scroll to the bottom of the Verify window.
- Enter your code into the Enter Codes text box exactly as shown in the table above.
- Click the green Submit button to claim your rewards instantly.
If a brand-new code does not work on your first attempt, exit the game completely and rejoin. Relaunching places you on a fresh server that may have the latest game build where the code activates correctly.
Why Are My Codes Not Working?
If a code throws an error, one of these reasons is almost always responsible:
- You have not joined the RoDark Studios Roblox Group. This is the most common reason codes fail. Group membership is a hard requirement before any code will work.
- The code has expired. RoDark Studios does not always announce expiry dates in advance, so codes can stop working without warning.
- There is a capitalisation error. Codes are case-sensitive. One wrong letter breaks the redemption entirely. Copy-paste from the table above to eliminate this risk.
- You are on an outdated server. Exit the game and rejoin to land on a server running the latest game version.
The best places to catch new codes early are the official RoDark Studios Roblox Group and the RoDark Studios Discord server, where announcements and community updates surface before anywhere else. Bookmarking this page also ensures you can check back for the latest additions without needing to monitor every source yourself.
Is There a Coding Simulator 2 Discord Server?
Yes. Coding Simulator 2 has an official Discord server run by RoDark Studios. You can join it to stay up to date on game announcements, chat with other players, participate in the community, trade, share content, and report bugs directly to the development team. New codes occasionally surface there first before being posted anywhere else.
