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.
THREE TIERS FREE, EVERY DAY
Casual, Standard and Hard, each with a measured difficulty rating. Three fresh puzzles daily. Start where you are comfortable and climb. The daily Fiendish chart comes with the Guild.
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.
Play offline any time. Sign in with Apple to sync your history and play ranked.

You get a nautical hex map and a set of survey notes to find the one mistranscribed spot on the chart. Super smart spatial logic and zero fluff. Little bit of a learning curve but the tutorial helps a lot. Check it out if you love deduction games!
FIXES A CRASH ON LAUNCH
1.4.8 would not open on phones running iOS 27. This update fixes that. Everything below arrived in 1.4.8 and is unchanged.
YOUR FIRST CHART IS CASUAL
New players now start on the Casual chart and move up to Standard after their first solve. Solve a Casual chart and the next one up is a tap away.
REMINDERS AT YOUR HOUR
Choose when the daily nudge arrives: 7am, 9am, 12pm or 7pm. If a streak of two or more is about to break, you get one warning that evening. You can switch either off in Settings.
A SHORTER WAY THROUGH THE WALKTHROUGH
Skip is on every page. The last page is where you sign in with Apple or Google to keep your record, and it stays out of the way if you already have.
The Today tab also remembers which chart you were on.
