The objective is to complete the colored knitted pattern shown at the top of the screen. To do this, you must first create full spools of the required yarn colors by solving a puzzle at the bottom. Drag and drop smaller spools of the same color and number onto each other to merge them into a larger spool. Once a full spool is created in the top row, drag the thread from that spool to the matching color block in the pattern above to begin knitting. Repeat this process of merging spools and applying the yarn until the entire pattern is filled and the level is complete.
You can only merge spools that are the same color and have the same number on them. The puzzle board has limited space, so you must merge spools to make room for new ones to appear. Some spools are marked with a question mark; you must merge them to reveal their color. Each full spool contains a specific amount of yarn, indicated by a percentage, which depletes as you knit.
Prioritize merging the colors that are needed for the main pattern to progress efficiently. Try to clear the lower sections of the puzzle board first to create space for new spools to drop down. Plan your merges in advance to avoid getting stuck with no possible moves. You can continue merging spools on the puzzle board while the yarn is automatically knitting the pattern at the top.
