Color Sudoku: Logic Blocks

A fresh Sudoku-style logic game: fill each color region with 1–N and no adjacent repeats (even diagonally). Clean design, smart notes, hints, and difficulty from Easy to Expert.

Highlights: Color regions: each region uses numbers 1–N once. No repeats: adjacent cells (incl. diagonals) can’t match. Play your way: Notes, Undo/Redo, and Hints when stuck. Progression: Easy → Expert with daily challenges. Custom themes: pick palettes that match your mood.

How to play: Tap a cell and place a number. Use notes to track candidates. Complete every region with 1–N, with no matching neighbors.
