Fold Merge is an offline number puzzle made for the folding display of iPhone Duo. Swipe either half to line up numbers, then bend the phone inward to merge them.

How to play

• Swipe one half at a time. Equal tiles in that half merge as they slide.
• Bend the phone inward a little to fold. The pair meeting at the fold merges first, then equal neighbours within each half.
• Open the phone flat again before the next fold. Every move that changes the board adds a tile; the run ends when no move is left.
• Replay the lesson any time from Pause → How to play.

Accessibility

With VoiceOver or Switch Control, each lane offers swipe actions and "Fold both halves". Fold Merge follows Reduce Motion and your text size.
