Puzzle & Action: Treasure Hunt, known in Japan as 2do Aru Koto wa Sando R, is a puzzle video game released for the Sega Titan Video in 1995, and ported to the Japanese Sega Saturn by CSK Research Institute Corp. in 1996. Puzzle & Action: Treasure Hunt is the third and final instalment in the Puzzle & Action series, after Puzzle & Action: Tant-R and Puzzle & Action: Ichidant-R. Like the previous games, players play a series of timed mini games to overcome enemies. Two players are supported.

Gameplay is similar to the previous games, although the games are in 3D. There are four rounds of a number of timed mini games, and two players are supported. Twenty-two categorised mini games are featured, and like the previous instalments, there is a 'Free Play' mode where they can be practised. The Saturn version features a RPG-style 'Original mode', which features a shop where items such as torches and brooms can be purchased.
