faq
Why does Check still say not solved?
Some links may be open, disconnected, or part of a closed loop. Keep rotating and run Check again.
Do all modes use the same logic?
Yes. Each mode keeps the same rules and changes board size and wrap behavior.
Can I play on mobile?
Yes. Tap to rotate, long-press to pin, and use toolbar actions for puzzle management.
