All puzzles completed. A clever and enjoyable logic puzzle game, RYB's puzzles present players with a pattern of interlocking shapes and the challenge to assign appropriate colours based on clues from adjacent shapes (e.g., one blue and two yellow circles indicating three neighbours with those colours). These start off very simple but eventually become quite challenging at times, with puzzles grouped into sets that generally each introduce a specific new mechanic, neatly introduced, wordlessly, through some initial examples. RYB gets a recommendation from me as a slow-paced, relaxing and satisfying experience.
