Weft: Thread Logic

A hand loom in the golden light of late afternoon, and two threads to lay: gold runs across, indigo runs down. Fill every cell the right way, and the cloth weaves itself before your eyes.

Weft is a calm, clever two-thread logic puzzle in the Binairo / Takuzu family. There is no luck and no guessing: every loom has exactly one solution, and you can reach it by reasoning alone.

HOW YOU PLAY
• Never three alike side by side, across a row or down a column.
• Every row and every column holds as many gold threads as indigo ones.
• On Hard and Expert, no two rows are alike and no two columns are alike.
• Tap a cell for gold, again for indigo. Drag from a thread to lay the same thread in a line.
• Thread counts beside every line show what it still needs.
• Gold and indigo differ in direction as well as colour, so the loom reads without telling colours apart.
• Undo and redo any move.

HINTS THAT TEACH
Stuck? The hint first outlines where to look, then explains the reasoning – and only makes the move if you ask. The first time a new idea comes up, it is explained in general, so you learn the trick instead of just getting the answer.
