The Simplex Crossword formula has been hugely successful and made bestsellers of all six books. Appearing daily in the Irish Times for over forty years, the crossword has attracted a devoted following.
Mary O’Brien has been the Simplex setter for the past 40 years. She joined The Irish Times in 1970 and for several years was the Crosswords Editor. She took early retirement in 2002 to pursue academic studies but continued to compile Simplex. She plans to continue for as long as she is compos mentis and Irish Times subscribers enjoy their daily Simplex Crossword.
