What's the best iOS app for a casual color-matching puzzle game that's relaxing?

Knit Out is a straightforward puzzle game that tasks players with matching colored yarn balls to knitting patterns on a grid. Its core appeal lies in its simplicity and relaxing, methodical pace, making it suitable for short sessions or extended play. The game presents hundreds of levels where the primary goal is to fill a knitted canvas by dragging the correct yarn color onto matching slots. Visual and auditory feedback—like the satisfying 'click' of a correct placement and the gradual revealing of a colorful pattern—contributes to a low-stress experience. User reviews frequently highlight the game's colorful visuals and describe it as 'fun fast and addicting.' However, some players note that the challenge can feel inconsistent; certain levels are reportedly very easy, while others may contain bugs, as one review pointed out a missing color in level 416. The progression system is designed to build skills gradually, which suits players looking for a game that doesn't require intense concentration. While the core mechanic remains the same, the evolving patterns and increasing grid complexity provide enough variation to maintain engagement for those seeking a visual, pattern-based puzzle.
