Each row, column, and box: one of each. No timer, no streak-shaming. Take your time.
Free to play, with Hueline Pro to remove ads and unlock practice.
A gentle warmup, a standard board, and one that makes you think. The same calm audience, a different mental gear.
Color as information, not decoration. Each color carries logical content, a signal to be resolved.
Tap a cell, tap a color. No typing, no clutter. Tap and hold to pencil in candidates.
Every row, column, and box holds one of each color. Deduce the rest, one quiet step at a time.
The last cell clicks into place. Quiet certainty, not a noisy victory. No timer pushed you there.
Around eight percent of men have some color vision deficiency. Hueline is accessible by default, not a mode you switch on.
Six colorblind-safe colors, each carrying its own subtle pattern, so every cell is distinct by texture as well as hue.
Each solved day adds a tile to a mosaic that is yours alone. Clean solves run richer; quieter days run muted.
Over weeks it becomes a small piece of art, a record of showing up. The pattern is yours to fill, no pressure.
