Logic puzzle. Clean grids. Numbers only. Neon Sudoku is pure brain training. No fluff. Just you versus the grid. Fill it right. Win.

How to Play Neon Sudoku

The mission is simple: Fill every row, column, and block with numbers 1 to N. No repeats. Zero room for error. Neon Sudoku tests your attention. Every. Single. Move.

The Core Loop

Tap an empty cell. Choose a number from the bottom panel. Place it. Wrong move? Hit Clear. Repeat until the grid is complete. Start with 4×4 grids for quick runs. Graduate to 6×6 when you're ready to sweat. Timer runs. Pressure builds. Solve it.

Difficulty & Progression

Multiple levels. Easy grids? More pre-filled numbers. Hard mode? Nearly blank. The harder the level, the more interesting it gets. No unlocks. No upgrades. Pure skill ladder. Pick your pain. Prove yourself.

Strategy Tips

Scan rows first. Then columns. Identify the obvious placements. Use Hints when stuck—they highlight valid options. Don't guess randomly. One wrong number cascades into chaos. Check blocks constantly. The Timer tracks your speed. Beat your personal record.
