Is there a good Android app for a relaxing, tactile puzzle game about untying knots?

Unravel Master is a puzzle game focused on the simple, methodical task of untangling interconnected lines. The core gameplay involves tapping and dragging nodes to straighten colored lines without them crossing. This creates a focused, almost meditative experience suited for short sessions or winding down. Specific features include hundreds of progressively complex knot patterns, a subtle sound design that provides satisfying audio feedback with each successful move, and a hint system supported by optional video ads. This ad-supported model allows players to proceed when genuinely stuck, a system some reviews note is a fair trade-off for free gameplay. However, a notable technical limitation exists: multiple user reports confirm the game can freeze on level 229, displaying an unresponsive screen with foreign text. While this bug disrupts progression for dedicated players, the sheer volume of levels preceding it offers substantial content. The visual design is clean and colorful, avoiding unnecessary clutter to maintain its calming aesthetic. For those seeking a puzzle game that emphasizes tactile problem-solving over narrative or time pressure, Unravel Master delivers a consistently engaging, if occasionally buggy, experience.
