This light-hearted volume argues in a humorously dictatorial tone that "The jolliest indoor games for boys and girls demand a floor.

"[1] Illustrated with photographs and drawings, it briefly describes a number of games that can be played on "well lit and airy" floors with "four main groups" of toys: soldiers about two inches high (Wells regrets the "curse of militarism" that makes civilians hard to find), largish wooden bricks, boards and planks,[2] and electric railway rolling stock and rails.

Wells describes how the boards and planks can be used to set up various imaginative geographies to play the "game of wonderful islands" in which the floor is the sea,[6] create the setting for "twin cities" (to allow his two sons a measure of independence in their creations),[7] or undertake engineering projects (he describes the building of funiculars in some detail).

[8] Floor Games has been regarded as a precursor not only of learning through play but also of nonverbal child psychotherapy.

A recent edition of the book was published by Skirmisher Publishing LLC in 2006 and includes a foreword by game design giant James F. Dunnigan an introduction by game designer and author Michael J. Varhola.
