How to Redeem Puzzles and Survival Codes
Redeeming these codes isn’t exactly the same for everyone. Depending on whether you are playing on an Android or an Apple device, the steps shift slightly. Here is exactly how to get those rewards into your bag.
Android Code Entry
If you are on Android, you have the easy route. You can claim everything directly inside the app without messing with external websites.
- Open the Menu: Tap the More (+) icon at the bottom right of the main screen.
- Go to Settings: Hit the gear icon.
- Find the Box: Tap on Box—many players overlook this, but it is your designated gift code box location.
- Claim: Type in the code and hit Claim.
Pro Tip: Be careful with Android code entry if you are copy-pasting. The game is notoriously picky about “trailing spaces” (an empty space after the last letter). If a valid code fails, backspace once to make sure no invisible characters are blocking your loot.
Puzzles and Survival iOS Redemption (iPhone/iPad)
For the Apple users out there, you might be frustrated looking for that “Box” button. Due to Apple’s policies, it doesn’t exist in the app. You are probably asking, is there a redemption link for iPhone users?
Yes, there is. Since you can’t claim rewards inside the game, you have to use the official 37Games redemption center:
- Visit the Site: Go to the Puzzles & Survival Redemption Page.
- Enter Details: Select your Server, enter your Character Name exactly as it appears in-game, and paste the code.
- Redeem: Click Redeem, and the items will be sent to your in-game mailbox instantly.
Troubleshooting Tip for iOS: If the site says “Character Not Found,” double-check your Server ID. You can find it on your loading screen (top left) or by tapping your avatar in-game > Settings > Character Management. This step is crucial for smooth Puzzles and Survival iOS redemption.
Where to Find More Free Diamonds & Codes
I try to update this page the second a new code drops, but sometimes the devs release limited-quantity rewards that vanish in minutes. If you want to stay ahead of the curve, you need to know where to look.
1. Join the Discord This is non-negotiable. The community is faster than any website. There is a dedicated channel for Official Discord codes where players ping everyone the moment a new reward goes live. It’s also the best place to find an active alliance if yours is dead.
2. Follow the Facebook Page The devs love engagement. They frequently post “Spot the Difference” games or trivia on their Facebook fan page. If you participate, they often DM you unique keys or release global Survivor event codes once the post hits a certain number of shares. It’s an easy way to grab extra diamonds while you’re doom-scrolling anyway.
Why Is My Puzzles and Survival Code Not Working?
Nothing kills the mood faster than typing in a long string of letters just to see an error message. If you are scratching your head asking why is my Puzzles and Survival code not working, it is usually one of these three reasons:
- It’s Ancient History: Most codes have a short shelf life. If you grabbed a code from a forum post six months ago, it’s likely on the expired codes list by now.
- The “Fat Finger” Syndrome: The game is incredibly picky. Capitalization matters. If the code is
PNS777, typingpns777might not work. Also, watch out for “trailing spaces”—if you copy-paste, you might accidentally grab a blank space at the end. - Region Locking: Some codes are specific to certain versions (like the Japanese version) or platforms. A code meant for a specific Android promotion might throw an error if you try to redeem it elsewhere.
If you keep getting errors, stop forcing it. It’s better to hunt for PNS latest codes that are actually verified than to waste time on dead ones.
Conclusion
The apocalypse doesn’t wait for anyone, and neither do these expiration dates. I’m constantly scouring the official channels to keep this guide fresh, because running out of speedups in the middle of a war is a nightmare we all want to avoid.
