Yarn Jam - Unravel Wool Sort

This is a relaxing, solo puzzle game played in portrait mode that can be enjoyed in short, interruptible sessions. While the core gameplay is free and playable offline, players will likely need to watch ads or spend money to progress past certain levels, as it can become pay-to-win. It's a good fit for players looking for a casual time-killer that doesn't require intense focus or a powerful device.
