Contagion

How to Play

• Everyone gets the same 25×25 grid every day. It resets at 00:00 UTC, for everyone, at once.
• There's no fog and no camera panning — the whole grid is visible the moment it loads. Move the cyan marker (you) to the gold marker (exit).
• Three separate corrupted zones start on the outer edge — the maze itself is identical for everyone that day, but exactly where the corruption begins is unique to your own session. Every 1.5-2.5 seconds, each zone independently branches — 2 to 5 new cells at random, picked from wherever it currently borders open corridor. None of it ever stops or reverses.
• The corruption never blocks your path on its own. But if it ever touches you, that's it — you lose control completely. Every half-second from that point on, you're teleported to a random cell on the grid, for the rest of this run. Your own input stops doing anything.
• This is permanent, not a scare — once infected, finishing is down to a random jump landing you on the exit, not skill. There's no way to shake it off. Play accordingly.
• Getting close to the exit speeds up the spread 4×. Getting infected is far worse: the spread jumps to 20× the base rate — five times steeper than just being near the exit.
• If the corruption ever consumes the entire grid, every wall on the board disappears and it becomes unreadable — so the attempt wipes clean and starts over completely: moves, time, and infection status all reset to zero, exactly as if you'd just loaded the level. A fresh maze, exit, and set of corrupted zones generate, and nothing starts spreading again until your next move.
• The grid gets bigger through the week — Monday's the easiest, Sunday's the hardest. Difficulty otherwise comes from the maze itself: the base branch timing and 2-5 cells per tick stay the same at every level.
• Use arrow keys or swipe to move. Come back daily to build your streak.
