PachPara 13 is one of the many titles in Irem's long-running pachinko simulation series. It features faithful 3D recreations of two pachinko machines made by Sanyo Bussan: CR Super Umi Monogatari M55W and CR Super Umi Monogatari M55X. There are two modes available: Tsūjō (Normal) mode allows the player to modify a wide range of settings for each machine, while Jissen (Battle) mode challenges the player to win as many balls as possible on the default settings with a limited starting pool and time limit. There is also a View mode where the various animations that play on the in-game display can be freely viewed.

The story mode this time is Pachi-Pro Fūunroku 5: Seishun-hen, set many years after the previous title at the end of the Showa era. Choosing either a male or female character, the player takes control of a recent high school graduate who has just discovered a knack for pachinko. The game focuses on the day-to-day life of a pachinko player, including practice and pachinko battles, maintaining good health, and of course, dating.
