This unusual four-player partnership game was invented by R W Willis of Trinidad and published in 1954. Although it has never become widely popular there are a number of devoted players, especially in New England (especially Western Massachussets). It is a trick-taking game in four deals using four 52-card packs mixed together, one quarter of the casrd being dealt out each time. Each player has a personal trump suit, and the main objective is to use cards won in tricks to collect complete 13-card sequences in one's own and one's partner's suit.
