Why Is My Slayer Training Code Not Working?

Sometimes codes don’t work, and it can be frustrating. Here are the main reasons why a code might fail:

• The code has expired and is no longer active.
• You typed the code incorrectly, including wrong letters or numbers.
• The code is case-sensitive, so capitalization matters.
• You might be trying to redeem a code meant for a different game or version.

If you get an "Invalid Code" message, it usually means the code is expired or entered incorrectly. Always copy and paste codes when possible to avoid typos.
