Misadventure #4 doesn't have an in-game title, but Misadventure #5 (Naked Nightmare) begins with a brief promotion for the rest of the series, identifying Misadventure #4 as "Casino of Pleasure"; which is mirrored in all the Softcore/Gamester advertising.
Originally for TRS-80 Model I and II; it was also listed for Colour Computer in the January 1983 Gamester advertising.
