About unlimited Neon
Unlimited mode deals a fresh Neon board every time you load the page or press New puzzle — no calendar, no cap, just another grid of glowing pairs waiting to be connected. Pick the board size you want, from a quick 5×5 to a full 8×8, and every board is generated and solver-checked to have exactly one way to join all the pairs while lighting every cell.
Because unlimited boards are not dated, they are the pressure-free place to practice: rehearse the rules on the how to play page, then drill the strategy guide's habits — edges first, never strand a dark cell, treat every line as a wall — until they are reflexes. Every board's address bar carries a seed link you can share, so a friend can race the exact same grid. When you are ready for the one that counts toward your streak, head back to today's daily puzzle.
