"Basic Rules

Hierarchical Structure: Boards are stacked in layers. Only by removing the upper boards can you access and remove the lower ones.

Removal Condition: Each board is secured by several yarn coils. You must collect all the yarn coils fixing a board to remove it.

Collection System: There are multiple yarn racks at the bottom of the screen. Each rack can only collect yarn coils of one specific color and has a maximum capacity of 3.

Rack Refresh: When a yarn rack is filled with 3 yarn coils of the same color, it disappears and a new rack (with a random color) appears.

Controls

Click to Select: Click on a yarn coil on a board. If there is a yarn rack of the matching color, the coil will automatically move to that rack.

Automatic Removal: Once all the yarn coils securing a particular board have been collected, that board is automatically removed.

Strategy Points

Removal Order Strategy

Top-Down: Prioritize removing the accessible boards on the uppermost layers first.

Dependency Analysis: Identify which lower boards are blocked by upper ones.

Chain Reaction Utilization: Look for key removal points that can unlock multiple boards at once."
