Stella: Dixit Universe

You must mark at least one card and may mark up to 10 cards on your Personal Slate (you cannot mark zero). (p.3)

Your Personal Slate must remain hidden from other players at all times; after selecting you pass the felt-tip to the left to signal completion and keep the slate hidden. If you fall during Reveal you must keep the slate in your hand because your crosses may still matter for others. (p.3, p.5)

That is a Fall: the Scout fills no stars for that card, can no longer fill stars or be a Scout for the rest of the round, and must keep their Personal Slate in hand. (p.5)

After announcing how many boxes you checked, the player who alone has checked more boxes than anyone else flips their Lantern Token to Dark; being "in the Dark" means if you fell at least once you must remove one star from each Spark/Super‑Spark before tallying points (if you never fell you score normally). The bonus star from a Super‑Spark still counts. (p.4, p.6)

Players who have fallen can still be part of Sparks or Super‑Sparks (their crosses may cause others to get Sparks), but fallen players do not fill any stars for those results. (p.5)

After resolving a reveal, the player to the left of the current Scout becomes the new Scout unless they have fallen or have no crosses left, in which case the turn passes clockwise to the next eligible player; the Reveal step ends when all players have fallen or when remaining players who didn't fall have no crosses left to show.
