About the library

Browse the full Neon puzzle library: 300 free, numbered connect-the-pairs puzzles. Unlike the daily board, every one here is available on demand — pick a number and start drawing. The library climbs the same ladder as the daily week in four bands of 75: puzzles 1–75 are 5×5 boards with four pairs, 76–150 are 6×6, 151–225 are 7×7, and 226–300 are the 8×8 boards with seven pairs.

Each puzzle is fixed: puzzle #12 is always the same board, so you can share a link, come back later, or race a friend and know you are lighting the exact same grid. Every board is generated by our own engine and solver-checked to have exactly one solution.
