Pachinko Paradise DX is the final PS1 release in Irem's long-running pachinko simulation series. It features reproductions of three pachinko machines made by Sanyo Bussan, all of which are returning from previous releases: CR Umi Monogatari 3R and CR Umi Monogatari 6 from Pachinko Paradise 2, and CR Wan Wan Paradise SK from Pachinko Paradise 3. Each machine features new background graphics not found in the original versions. 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. There is no story mode.
