それっぽい箱に纏わる話 (Soreppoi Hako ni Matsuwaru Hanashi)

それっぽい箱に纏わる話 (Soreppoi Hako ni Matsuwaru Hanashi) is a trick-taking game that is based on Bottle Imp. It is a must-follow trick-taking game where the trumps keep changing. Each card at or below a threshold number is a trump, and whenever a such a card wins a trick, the threshold drops to this new value.

Whoever is left holding a threshold token at the end of the hand when the round ends scores nothing and but takes some undealt cards as a penalty.

Play continues until someone reaches a target score.

The game adds event cards that are triggered when the threshold changes, that do things like make certain colors also trump, or odd/even, etc.
