Hueline: Daily Color Sudoku

Hueline is a daily color sudoku: the logic of sudoku, played with color instead of numbers. Every row, column, and box holds one of each color, exactly once. Three short rounds each day, about a minute or three of quiet deduction. No timers shouting at you, no streak-anxiety, no noise. Just a calm logic puzzle and a moment to think. If you love sudoku, you already know how to play. Hueline keeps the deduction you love and swaps numbers for color, so the same logic feels brand new. It is a puzzle you can solve before your coffee cools. A DAILY PUZZLE FOR EVERYONE Everyone, everywhere, solves the same daily color sudoku. A shared puzzle, a quiet thing you have in common. Come back tomorrow for a fresh logic puzzle. BUILT TO BE SEEN BY EVERYONE Hueline is a fully colorblind-accessible sudoku. Every color also carries its own texture and pattern, so you solve by logic and shape, never by hue alone. Patterns are on by default, with Standard, Deuteranopia, and Monochrome modes. A color sudoku that anyone can play, colorblind or not. A DAILY RITUAL Three rounds a day: one gentle 4x4 to warm up, then two 6x6 puzzles for deeper deduction. Tap to place a color, hold to leave a pencil note, and watch a soft sage glow whenever two colors conflict. Calm, tactile, unhurried sudoku. THE MOSAIC Every day you solve becomes a small woven tile. Over weeks your Mosaic grows into a quiet record of your puzzle practice, proof of all that deduction, with nothing shouting for your attention. STATS THAT STAY KIND Gentle stats only: streaks, perfect days, and how your solve time drifts over time. Encouragement, never pressure. HUELINE PLUS An optional Hueline+ membership opens up practice sudoku at any size and difficulty, hints without ads, an expert bonus round for harder deduction, extra pattern packs, Mosaic poster export, and an ad-free board. A daily color sudoku: logic, calm, and color, made to be seen by everyone. From J&B Creations.
