"Of glass it is, but the glass of it was tempered in the flames of hell. An Imp lives in it, and that is the shadow we behold there moving: or so I suppose. If any man buy this Bottle, the Imp is at his command; all that he desires - love, fame, money - all are his atthe word uttered... and unless a man remain content with what he has, ill will befall him."
The Bottle Imp is a trick-taking card game that is quite unique in this genre. In The Bottle Imp, the lowest cards are trump cards. The "price" of The Bottle Imp falls to that of the winning trump card. In this way the owner of The Bottle Imp changes until its value can no longer be undercut. Whoever has The Bottle Imp at the end of the hand earns negative points instead of positive ones. Careful play of your trump cards is required to avoid taking The Bottle Imp and getting negative points!
The Bottle Imp is based on the short story by Robert Louis Stevenson.
