A daily logic puzzle: every clue is true, one hex is a lie
2 followers
Somewhere on today's map, one hex is drawn as something it is not. You get four survey notes, and every one of them is true. Only one hex can satisfy all four at once; that hex is the liar. "The lie touches exactly 0 reefs." "The lie is drawn on reef or heath." Put those together and every reef is dead. You are not guessing, you are proving. One map a day, the same one for everyone, about three minutes. Free in the browser, no account.
Every note the cartographer gives you is true. The only thing that lies is the map itself.
One hex is drawn as something it is not. You get four honest notes, and exactly one hex on the island can satisfy all of them at once.
A recent chart told me the lie touched no reefs, and that it was drawn on reef or heath. Every reef on that island sat beside another reef. Heath, then, and I had not marked a thing yet.
That is the whole game: the moment you stop guessing and start knowing.
