Every switch follows a rule hidden somewhere in the real world. Find them.
Each day you set 24 toggles. Each night at 23:00 UTC the lamps tell you which were right. The answers come from public data anyone can look up. Try three now: the practice week below runs in about thirty seconds.
Season 1, The Harbor, opens Monday 4 January.

How a season works
Set your board
A season is 84 days. You start with 8 of the 24 toggles live, and more open as you get them right. Your board saves as you go, so there's nothing to submit.
Read the lamps
At 23:00 UTC every board locks and the lamps light: right or wrong for switches, hot, warm or cold for dials, how many lights you got for a light bank.
Follow the clues
Each toggle gets three clues, by days 7, 21 and 42: the general area, the kind of source, then the exact source. Crack a toggle before a clue lands for a bigger bonus. From day 1, the season's riddles in the Charter point at the kinds of data behind the board.
Win the season
Thirty perfect days inside any 35-day stretch wins. Several people can win, and everyone gets a final ranking by points.
New kinds of toggles arrive with later seasons. Read the full rules
The Charter, in short
- Each toggle follows one free, public source that anyone can read on a web page, except two that follow your own history.
- Every value is published before the 10:00 UTC snapshot, so every answer is knowable before the lock.
- A source is changed only by a short list of named steps, such as a last digit or a threshold.
- Nothing changes mid-season, except a broken source swapped for a reserve, with practice days before it counts.
