The current standard edition is Catan (5th Edition), released in 2015. It was rebranded from "The Settlers of Catan" to simply "Catan" to reflect its global brand identity.
Since 2015, numerous standalone scenarios (e.g., Seafarers, Cities & Knights, Explorers & Pirates) and themed editions (e.g., Game of Thrones Catan, Star Trek Catan, Catan: Junior) have released. However, the core base game remains the 5th Edition. As of 2024, no "6th Edition" base game exists—expansions and variants build upon the 5th Edition foundation.
