Solo Decks
Decks owned by a Solo Learner for independent study.

Build Solo Decks, follow a Daily Mission, clear Maintenance, grow with new Cards, and turn independent study into Arcade progress.


Maintenance handles due Cards up to your Maintenance Maximum. Growth brings new Cards into the loop when you are ready.

Create independent Decks, study them quickly, and let Solo Progress track the schedule, goals, rewards, and SRS State.

Free Play lets you browse a Solo Deck without changing SRS State or Solo Progress. Boss Fight checks mastery when you want a stricter challenge.
