Neon Sudoku

Neon Sudoku is a free puzzle game made with AI by @xen, and you can play it right here in your browser.

Neon Sudoku is classic number-puzzle bliss reimagined in electric neon. Tap into a glowing 9x9 grid and fill every row, column, and box with the digits 1-9.

Race the clock on 100 hand-paced levels that get tougher every 10 stages — from breezy starts to brain-bending master grids. Finish fast to earn up to three stars on every level, then chase a perfect run.

Beat each difficulty tier to unlock a brand-new neon board skin — Cyan Pulse, Magenta Surge, Acid Green, and more — and equip your favorite look. Pencil in candidates, watch for live conflict highlights, and build the perfect solve.

Relaxing yet competitive, with a sleek glowing style and just-one-more-level pull.
