Hueline: Daily Color Sudoku

About

Hueline is a daily color puzzle — classic sudoku, played in color. Every row, column, and box holds one of each color, never a repeat. No numbers, no math, no clock racing you. Just a quiet shape of logic to fill in, once a day. ACCESSIBLE BY DESIGN Every color also carries its own pattern, turned on by default — so Hueline is fully playable whether or not you see hue the same way. Here, color is information, never decoration. THREE ROUNDS, ONCE A DAY Each day brings the same three puzzles to everyone: a gentle 4×4 to warm up, a 6×6 to settle into, and a tougher 6×6 to finish. Most days take a minute or two. When you're done, you're done — come back tomorrow. THE MOSAIC Every day you solve adds a small tile to your Mosaic — a wall of color that grows, week after week, into something only your streak could make. Clean solves shine. The pattern is yours. CALM BY DESIGN No timers bearing down. No red, no buzzing, no flashing. A wrong move gets a soft sage glow, not a scolding. Warm paper, quiet type, and a single puzzle to think through. Hueline is the opposite of an arcade.
