Two of his more popular creations include the chess variant Baroque chess (also known as Ultima) and Crossings, which later became Epaminondas. Eleusis was also successful, appearing in several card game collections, such as "Hoyle's Rules of Games" and "New Rules for Classic Games", among others. In 1963, Abbott himself released a publication, "Abbott's New Card Games", which included instructions for all of his card games, in addition to Baroque chess. Abbott also invented logic mazes, the first of which appeared in Martin Gardner's "Mathematical Games" column in the October 1962 issue of "Scientific American". One of the more prominent of these is "Theseus and the Minotaur", which was originally published in the book "Mad Mazes". His game "Confusion" was named "Best New Abstract Strategy Game" for 2012 by GAMES Magazine.
