Frequently Asked Questions
Rules, save behavior, added constraints, and mobile controls.
What is an echo clue?
An echo clue only reveals field strength, not polarity. You need to combine it with exact clues and flux rings.
How do quantum links work?
Linked cells always stay in inverse sync. Setting one end to +1 immediately forces the far end to -1, and clearing one clears both.
How should I read polarized flow?
Judge it from each clue tile. If the neighbor one step along the arrow is red, it counts as +2. If the neighbor one step opposite the arrow is blue, it counts as -2. The other four adjacent cells keep their normal values.
Why do I see overload warnings?
A clue or flux ring is marked overload when your current algebraic sum already crossed its target direction.
What is a threshold clue?
A threshold clue only says the final sum must stay below or above a boundary such as <2 or >0, so it becomes decisive when combined with the rest of the board.
Is progress auto-saved?
Yes. Every move persists to local storage so you can resume after refresh.
Does hint reveal the full solution?
No. A hint only fixes one incorrect interactive tile each time.
