QWIK-SANE is a topological puzzle that will challenge and delight people devoted to solitaire games calling for careful reasoning. It is simple in both design and theme, yet calls for concentrated effort to achieve the precise objective. Almost anyone willing to apply careful attention and patience will be able to “work” this puzzle, but solving the problem in the specified manner required is a genuine challenge. QUIK-SANE was developed by James R. O’Neil, a retiree from the U.S. Treasury Department, after 39 years of government service. Throughout his working years, Mr. O’Neil pursued an avocation of inventing toys and games for which he holds several patents.
