Napoleon or Nap is a straightforward trick-taking game in which players receive five cards each and whoever bids the highest number of tricks chooses trumps and tries to win at least that number of tricks. It is often described as a simplified version of Euchre, although David Parlett believes it is more like "an elaboration of Rams". It has many variations throughout Northern Europe, such as Fipsen. The game has been popular in England for many years, and has given the language a slang expression, "to go nap", meaning to take five of anything. It may be less popular now than it was, but it is still played in some parts of southern England and in Strathclyde. Despite its title and allusions, it is not recorded before the last third of the nineteenth century, and may have been first named after Napoleon III.

Rams is a European trick-taking card game related to Nap and Loo, and may be played by any number of persons not exceeding nine, although five or seven make a good game. In Belgium and France, the game of Rams is also spelt Rammes or Rems, in Germany, Rams, Rammes, Ramsch, Ramschen, Ramscheln or Ramsen, in Austria, Ramsen and Ramschen, and, in America, Rounce. The basic idea is fairly constant, but scoring systems vary. It was a widespread European gambling and drinking game that is still popular today. During the 19th century, it was introduced as Rounce in America and played with a 52-card deck without any difference between simples and doubles and with no General Rounce announcement. In the modern German variety of the game, Ramscheln, the 7♦ is the second best trump ranking next below the ace.
