Players have to travel across the globe, uncovering clues to work out where crooks are hiding. In each location, the player hunts for clues using their naked eye, an x-ray, and ultraviolet light, similar to a hidden object game. Players undertake a street racing minigame when chasing down the crook. Each case has a time limit, with hours being used whenever the player goes to a new country. They can use coins to speed up this travel time. The game comes with an encyclopedia to help players who cannot decrypt a clue. Intel RealSense Technology allows players to use gesture control to do things like pick up clues and fly a plane. The use of puns, which is a staple of the series, is continued here, with names of crooks including "Hal Apenyo" and "Bea Carefull". The free version of the game contains Pack 1: Museum Heist! (5 missions), while Pack 1: Museum Heist! (5 missions) and Pack 2: Monumental Emergencies! (10 missions) can be purchased together. In the iOS version, each level sees the player start a case, travel the world, collect clues, fill out a warrant, and finally chase the crook. Players can track their progress on the leaderboard via the Apple Game Centre. In this version, players have two travel options: normal, and express, the latter of which takes up in-game currency. In each location players search for clues via their fingers' manipulation of the touch pad, and as witnesses offer them information, they can start to build up their warrant.

The first hint of the new game was made in January 2015 via a teaser trailer released on Houghton Mifflin Harcourt's YouTube channel entitled ACME Alert: Carmen Sandiego™ is back with a new game!. It said the game would be "available soon for free download on Amazon.com". A few months later in March, Edutainment Weekly quoted Houghton Mifflin Harcourt communications director Jennifer Berlin as saying that there would be future developments regarding an iOS app. Further details were peppered throughout press releases leading up to the game's official launch date: Carmen Sandiego Returns was advertised as being a bilingual game in English/French, and was noteworthy for offering the company "an opportunity to leverage legacy assets with a strong brand and fan base". On May 14, the game became available on Amazon, while in November, the app version was released to commemorate the 30th anniversary of the original Carmen Sandiego game. EdSurge noted that "her re-emergence coincides with a resurgence in the popularity of educational games", which had been in decline since the turn of the millennium.
