DS Games That Only Use Touch Screen & Buttons: Very Few — System Designed for Dual-Screen

Very few DS games use only touch + buttons—the system was designed for dual-screen interplay. However, these heavily favor touch:

• Brain Age / Brain Training: Touch-driven puzzles; buttons only for menus
• Elite Beat Agents / Ouendan: Rhythm gameplay entirely touch-based (tap/swipe/flick)
• Cooking Mama series: Minigames use touch for chopping, stirring, plating
• Professor Layton series: Puzzles solved via touch; top screen shows map/story (still used)

Even these use buttons for menus, pausing, or confirmation. For purely touch-only games, look at mobile (iOS/Android) or Switch titles designed for handheld touch play.
