Shuffling · no sign-up needed

A reading in three cards

  1. I

    The Question

    Write it down

    A question on the front, the answer on the back.

  2. II

    The Turn

    Turn it over

    Say it out loud, then tap the card to check.

  3. III

    The Verdict

    Grade yourself

    Moon, Star or Sun decides when it comes back.

The schedule

Every card keeps its own orbit.

Miss one and it swings straight back. Know it and its orbit widens, until a card from spring returns in autumn, still bright.
