A quiet collision of match-three logic and number doubling. Slide, merge, and chain through one thoughtful puzzle a day—offline and tracking-free. Chainfold is a finite-move puzzle where match-three logic meets number doubling. Nothing drops in, nothing refills, and nothing is randomized while you play—every move can be reasoned through. Slide numbers into adjacent empty spaces to shape the board. Swapping two numbers must immediately make a match of three. Matches fold into double, and a new number can trigger another chain. Reach the target before you run out of moves. Unfold one new puzzle every day: • The same day always means the same puzzle, even offline • Revisit the last seven days and finish a fold you missed • Build a streak and improve your personal best • Sync progress across your devices through iCloud • Share a spoiler-free starting board so friends can think first • Daily puzzles draw from 200 solver-verified boards with a gentle difficulty curve Every slide, merge, and chain is paired with restrained sound, haptics, and a tactile folding animation. Chainfold supports VoiceOver, Dynamic Type, increased contrast, Differentiate Without Color, and Reduce Motion. No Chainfold account. No ads. No tracking. Progress is stored locally first and syncs across your devices through iCloud. Every move counts.
