Cyanotype

How to Play

• Everyone gets the same print every day. It resets at 00:00 UTC, for everyone, at once.
• You can always see the full 3×3 square around you, diagonals included — everything past that starts as blank, unexposed paper.
• A band of sunlight develops the paper left to right, purely on a clock that starts the moment you first move. Whatever it's crossed turns Prussian blue and stays lit forever, whether you're standing there or not.
• Nothing about the exposure depends on how you're playing — push ahead into the blank paper and feel your way by touch, or hang back and let the light do the work before you commit to a route.
• Tap 📸 Flash (or hit spacebar) for a brief, wide look around you — it fades again after a couple seconds. You only get a handful of charges per attempt, so use them wisely.
• Scattered along the route are test strips. Walk onto one and it permanently lights a patch of ground around itself, on top of whatever the sweep has already exposed.
• Find the gold exit. It only shows up once you're close enough, or once the light happens to reach it.
• The print gets bigger through the week and the light crosses slower — Monday's the easiest, Sunday's the hardest. Pick a level, Beginner through Extreme — it controls how fast the exposure develops, how many flash charges you get, and how far apart the test strips are.
• Use arrow keys or swipe to move. Come back daily to build your streak.
