## What is Nodelock?

One solution. Always. Never a guess.

Nodelock is a daily tile-rotation puzzle. Tap a tile to turn it 90°, mate every wire stub with its neighbour, and light the whole grid from a single amber source. That is the entire control surface: one verb, no menus, no failure state, no timer.

WHAT MAKES IT DIFFERENT
Every board is solvable by pure local deduction and has exactly one solution — not as a claim in a description, but as an acceptance gate. A board only ships if a search-free solver settles every tile with zero guesswork AND an independent search confirms no second solution exists. Boards that would make you guess are thrown away before you ever see them.

WHY YOU'LL STAY
• A free daily board, identical for every player worldwide
• Two streaks: one for showing up, one for solving without a hint
• Endless mode with an explicit difficulty picker, not an invisible ramp
• A free archive — replay any past date, reconstructed from its seed
• Hints reveal the next real deduction, never the answer

MADE TO BE COMFORTABLE
• A VoiceOver-solvable board and a colorblind-safe palette
• Never colour as the only signal
• Play in English, German, Arabic, Persian or Kurdish (Sorani)
• Proper right-to-left layout and localized numerals
• Fully offline. No account, no sign-up, nothing to wait for

FREE, HONESTLY
The daily, the archive, streaks and stats are free, with light optional ads. Rewarded video is opt-in and only ever buys a hint. There are no banner ads on the board. One small purchase removes ads for good — no subscription, no energy, no timers.
