Merge colors. Clear the board. Relax your mind.

Hue turns color theory into a puzzle. Every arrow slides in one fixed direction until it hits an obstacle, the edge of the board, or another arrow — and when two arrows collide, they don't cancel out, they blend, following the same rules as mixing paint: red and yellow make orange, blue and yellow make green, red and blue make purple. A faint ghost arrow previews the result before you commit, so every tap is a small piece of alchemy rather than a guess.

It's built to be the opposite of stressful. There's no timer, no lives, and no energy system to wait out — just a generous move limit and an instant, free restart if you run out. Under the hood it's a deterministic puzzle engine: all 500+ levels are procedurally generated and solver-verified, so every board is guaranteed to be solvable, and new mechanics — obstacle tiles, sequential gates, locked arrows, double-color gates — unlock gradually as you progress toward the toughest 7×7 "Nightmare" boards.

Hue also plays fair with your eyes: an optional colorblind mode adds a distinct symbol to every color, and you can switch between a soft light theme and a true dark theme at any time. The whole game runs offline, with your progress backed up automatically, so it's just as happy on a plane as it is on your commute.
