Begin by examining the knitting pattern at the top of the screen to identify the sequence of colors required. On the puzzle board at the bottom, find and match three or more discs of the same color to create a corresponding spool of yarn. Once a spool is created, tap and drag the thread from the spool to the correct color section on the knitting pattern above to fill it in. To clear discs that are locked with chains or hidden by question marks, you must make a match with adjacent discs. Continue this process of matching discs to create the necessary colored spools and applying them to the pattern until the entire design is complete.
The number displayed on a spool indicates how many sections of the pattern it can knit. Pay close attention to the order of the colors in the pattern, as you must fill them in correctly. You have a limited number of lives, indicated by the heart icon in the top right corner, so plan your moves carefully.
Prioritize making matches that will unlock chained or hidden discs to open up more of the puzzle board. Focus on creating the specific colors that are immediately required for the next section of the knitting pattern to progress efficiently.
