You can combine cards of the same rank, prepare powerful Ultimate Moves, and build a team with familiar heroes.

Why Redeem Codes Might Not Work in The Seven Deadly Sins

A code can fail even when it appears correctly written. Here are the most common reasons:

  • The code has expired: Event and anniversary codes are usually available for a limited period.
  • The code was entered incorrectly: Check every letter and remove spaces before or after the code.
  • It was already claimed: Each coupon can normally be redeemed once per account.
  • The wrong server was selected: Your Netmarble ID and server must match your game account.

Also, avoid using codes made for The Seven Deadly Sins: Origin. It is a separate game with its own coupon system.

These rewards can give you extra materials for upgrading heroes, improving equipment, and preparing for tougher battles. Claim them early so you do not miss any limited bonuses.

You can also play The Seven Deadly Sins on PC or Mac with BlueStacks. A bigger screen makes the cinematic battles easier to follow, while keyboard and mouse controls provide a comfortable way to manage your cards and team.
