"Deep Psyche" was released in Japan on December 24, 2008, North America on April 20, 2009 and in the PAL region on May 8, 2009. The titular illusion deals with a series of pointed questions revealing the startling truth. All questions have answers involving numbers which are added up and will magically result in a big number. It also includes *Today's Special* which deals with showing the date set on the DSi system clock, hence this DSiWare asks if the system clock is correct when you use it for the first time. For some reason, a few others ask if the clock is set correctly despite not using it.
