Each code (including NSG666, NSG888, NSGHOT5, and the other listed codes) can be claimed once per account. Switching devices does not let the same account claim it again.
Code rejected?
Use the copy button for NSG666 or another listed code, then remove spaces before or after it. Capitalization matters: keep uppercase and lowercase letters exactly as listed. Check its status in the active list and code history. A rejection alone does not confirm that it has expired.

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.
Codes are sourced from the game's official Facebook page.
Questions & answers
What is the best way to get new heroes?
You will use Gold Keys for Advanced Summons and Bronze Keys for Normal Summons at the Hero Portal. Make sure to save your keys and only spend them during specific Summoning Events to maximize your chances of pulling elite 5-Star SSR characters!
Which hero factions should I focus on?
While the Mystic and Alien factions boast the most powerful (and rarest) heroes in the game, they are incredibly difficult to level up for F2P players. Early on, it is highly recommended to build a team utilizing the Mech and Gene factions, as their Hero Bonds synergize beautifully and their shards are much easier to obtain from the Hero Portal.
Do City Arena codes expire?
Some codes have a fixed expiry date; others are withdrawn without a published deadline. Check any expiry shown beside a code, and redeem it while it is still listed as active. The expired-code list keeps older codes for reference.
