The screen is blue. Brilliant!
30 levels · each one is different
Blue is a color puzzle where every one of the 30 levels uses a different trick to turn the entire screen blue. There is no single rule — some levels ask you to tap a hidden button, others to drag a slider, spell a word, count shapes, hold and release at the right moment, solve a mini lights-out grid, navigate a maze, or catch a moving target. Read the hint (💡 button) if you're stuck; it tells you the level's mechanic. When you solve a level, the screen fills with blue and you advance to the next. Progress is saved automatically.
Think laterally — the obvious interaction is rarely the whole answer. Look for subtle visual cues: a slightly different shade, a hidden element at a corner, text that doubles as an instruction. Many levels reward experimentation: try tapping, dragging, holding, and swiping in different areas. If a level has a timing element (a moving bar, a shrinking circle), wait for the right moment rather than rushing. Use the hint button liberally — it's free and gives just enough direction without spoiling the solution.
