Zombie Hero Showdown codes not working?

If you're having trouble claiming rewards, check these common issues related to Zombie Hero Showdown codes:

• The code has expired. Many codes have a short shelf life, sometimes lasting only a day or two. If you’re seeing an error, the code may have already been deactivated. Check the status tag next to each code on our list.
• Codes are case-sensitive. This game enforces exact capitalization — "VIP888" won’t work if typed as "vip888". Copy the code directly from our list to avoid mistakes.
• Already redeemed. Codes are single-use. If you’ve redeemed a code before — even months ago — it’s permanently claimed on your account and can’t be used a second time.
• Complete the tutorial first. For Zombie Hero Showdown, the code redemption feature is locked until you finish the tutorial. Play through the introductory stages, then revisit the code entry screen.
• Check your in-game mail. If nothing happened after entering "VIP888", don’t panic. Open your in-game mail or gift box — that’s where rewards are usually deposited.
• 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.
