Cartographer's Lie

Four fresh puzzles daily, Casual to Fiendish. Every one proved solvable by pure elimination before it is published. The setter can deceive. The setter cannot cheat.

One island. Forty-eight hexes. A handful of clues, and exactly one of them is lying.

Every day brings a new map and a new deduction. Read the clues, rule out what cannot be true, and find the single hex that fits. No guessing, no luck, no coin flips.

THE SETTER CAN DECEIVE. THE SETTER CANNOT CHEAT. Puzzles are built to mislead you, and a red herring is a legitimate weapon. But before a single one reaches you, a fairness gate proves that exactly one hex satisfies every clue and that you can reach it by elimination alone. Misdirection is fair. Ambiguity is not. A clue that eliminates nothing is banned outright.

FOUR TIERS, EVERY DAY Casual, Standard, Hard and Fiendish. Four fresh puzzles daily, each with a measured difficulty rating. Start where you are comfortable and climb.

TAKE NOTES YOUR WAY Tap to mark hexes, long-press for colour tags, highlight the map by individual clue. Or switch to Pure mode and hold the whole thing in your head.

THREE GUESSES Each one costs you more than the last. Solve it clean, or do not solve it at all.

SET YOUR OWN PUZZLES Build them in the composer with live candidate counts, a difficulty projection and Preview-as-Solver. You have to prove you can solve it before anyone else sees it.

STREAKS AND STATS Daily streaks with freezes for the days life gets in the way, a spoiler-free grid for sharing your solve, and a skill rating that tracks how you are actually doing rather than how you feel you are doing.
