One of a small number of "family" games that Renwal published under the Gamescience name after purchasing the company from Phil Orbanes Sr. (previously Gamescience had published wargames).
Players each have 10 pieces (numbered 1-10), and are trying to capture 5 consecutively numbered pieces (from any number of players). A piece can move as many spaces as the number of other pieces adjacent to it. That's most of the rules right there - like Sid Sackson's other abstracts, it's fairly simple (to understand, not necessarily to play well).
This is similar to Fields of Action, the rules to which were published in R. Wayne Schmittberger's New Rules for Classic Games (although originally considered for inclusion in Sid Sackson's own A Gamut of Games). However, that game is only for 2 players and has a few other differences.
