As with many other trick-taking card games, the idea is to acquire the most points. The Bottle Imp works by ensuring that the highest card does not always take the trick.
The player with the highest valued card that still fits under the price of the Bottle Imp receives the trick and also the Bottle Imp. The value of the Bottle Imp falls to the value of the winning card.
The owner of the Bottle Imp changes until its value can no longer be undercut. Whoever owns the Bottle Imp at the end of the game receives minus points instead of positive points.
Based on a short story by Robert Louis Stevenson.
In the 2003 edition the complete story by R.L. Stevenson is included (in both English & German) and the bottle is a nice wooden piece. Earlier versions had a stand-up cardboard piece that you cut out.
