Reversible Stitch

Pull a stitch to flip BOTH that button and its immediate right neighbor (if still present). Every button shows front ↔ back color. A line of three or more equal fronts disappears immediately; careless triples can strand the fourth button. Clear the entire textile within eight pulls. The right edge has no partner, so it can be adjusted alone. Plan linked flips before triggering a match.

Tap controls, or Tab then Enter/Space. R restarts. Numbered coordinates identify board cells. Every action is turn-based; take time to plan.

Two-sided tile manipulation is essential, not ordinary swapping.
