Common code errors in City Arena

City Arena codes can stop working at any time. Here are the most common reasons a code might fail and how to fix each one:

• The code has expired. Codes are often time-limited. Some expire within 24 hours of release. If a code isn’t working, it may have already expired. We mark codes as expired as soon as we confirm them.
• Codes are case-sensitive. This game enforces exact capitalization, so "NSGUP" won’t work if typed as "nsgup". Copy the code directly from our list to avoid mistakes.
• Already redeemed. For City Arena, each code can only be used once per account. If you’ve already claimed it, it won’t work again, even after reinstalling or updating.
• Complete the tutorial first. The code redemption feature is locked until you finish the tutorial. Play through the introductory stages, then revisit the code entry screen.
• Platform or region mismatch. This game is available on iOS, Android. Some codes only work on a specific platform or region, so make sure the code is intended for yours.
• Check your in-game mail. Rewards from codes like "NSGUP" don’t always appear on screen right away. Check your in-game mailbox, gift center, or inbox after redeeming, since items are often delivered there instead.
• Restart the game. Idle and incremental games sometimes need a full restart for code rewards to show up. Close the app completely, reopen it, and check your balance.
