What is City Arena?
City Arena: Hero Legends (formerly known as Nonstop Game) is a vibrant 3D idle gacha RPG that transports players into a modern-day fairy-tale city on the brink of war. The core gameplay loop revolves around assembling a 5-member squad from over 200 uniquely designed heroes across five distinct factions: Mech, Bio, Gene, Mystic, and Alien. With its hassle-free, double-speed automated battles and generous offline resource gathering, players can easily progress through the campaign. The game also offers deep strategic depth through Hero Bonds and formation positioning, alongside engaging game modes like the Mysterious Maze, Trial Array, and the highly competitive Guild vs. Guild Ace Tournament.

Why Aren't My City Arena Codes Working?
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 — "FreEGeMs" won’t work if typed as "freegems". 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 — make sure the code is intended for yours.
- Check your in-game mail. Rewards don’t always appear on screen right away. Check your in-game mailbox, gift center, or inbox after redeeming — 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.
