## What is Midnight Signal?

Midnight Signal is a calm circuit-rotation puzzle for iPhone and iPad. Turn the wires until every receiver has power and every open end is closed.

24 puzzles grow from small connections to a complete 7-by-7 network. Restore four districts, track your progress, and aim for three stars by completing channels without hints and within the rotation target.

• All 24 puzzles included in one purchase
• Fully offline, with no ads or subscriptions
• No account or login
• Undo, reset and one-tile hints
• Chinese and English, selected automatically with a manual switch
• Native haptic feedback with an off switch

Progress stays on this device. Deleting the app removes local saves; cloud synchronization is not included. Code and bilingual writing were made with AI assistance. Gameplay does not call an online AI service.
