In the Nintendo DS (DS) version, the gameplay is almost identical, although displays are split between the dual screen set up and touch screen controls are incorporated: puzzles make use of the touch screen and DS' stylus, while elements such as the map of Lospass are displayed on the bottom screen during navigation. A new feature dubbed the "Lost and Found Report" is added, giving players new puzzles to solve at the beginning of each day. Players also have access to a notepad within the Catherine computer, on which players can draw and write notes related to a particular puzzle. The amount of exploration done across Lospass by Mondo is documented using a Step Counter, and bonuses can be awarded based on the distance covered by Mondo. As the game progresses, additional costumes for Mondo are unlocked.
