Steps that match the board
Open the official Clover Time experience. Look for Settings and the Codes input shown in its official screenshot. Copy a current string from the Codes card, preserving capitals and punctuation, and follow the input’s on-screen submission control. The full navigation path and current prerequisites are not documented in the card text.
- If an error gives a prerequisite, follow that in-game message. Group membership is not stated as a requirement in the current Codes card.
- Whether the box is case-sensitive is not written on the card. Copy the printed capitals.
- Use strings published for Clover Time; other games have separate code lists.
- A code that only appears on a news site, and not on the Trello card, was never confirmed by the developer.
What a successful code does not do
The published SHADOW and NATCH rewards do not include a grimoire. SHADOW pays 30 Crystal Mana Spins, 2 Stat Resets and a +50% XP boost for 30 minutes. Rewards for the other eight listed strings are not published in the checked sources.
There is no official expiry clock or expired-code archive on the current card. A missing string is not proof of a particular expiry date. The in-game response determines whether a listed code works for your account.
