One on one · Arena of 6 · Free

Show them who the real Sherlock is.

The same puzzle, at the same second: first to solve it takes the round — and answering fast but wrong hands the point to the other player. Against your friends, or against the whole world.

kestrel challenges you.

Three real puzzles from the game, the same for both of you. First to solve it takes the point — and a wrong answer hands it to the other one.

Right here, no account, nothing to install.

Challenge a friend on three other puzzles

Three real puzzles from the game, word for word. There are four hundred and fifty-five written ones, plus twenty-seven families generated endlessly: you will never see the same one twice.

In the game

From the face-off to the leaderboard.

Your avatar against theirs, the same puzzle, the point to whoever solves it first. Then the arena of six, the challenge left for a friend who is asleep, and your rank going up.

With friends

Together, or whenever you like.

  • Pre-match screen: two players face to face.
    Live Face to face

    You invite them, they accept, off you go: three or five rounds, the same puzzle at the same second. The round closes the moment one of you finds it — so get some paper out: you have ten minutes, and so do they.

  • Turn by turn Even while they sleep

    You challenge a friend, play your three puzzles, and go to bed. They play the same ones whenever suits them — tonight, or in three days. Whoever finds the most wins; the clock only breaks a tie.

  • A private arena with six players.
    Private arena Up to six players

    One code to share, and the whole group hunts the same puzzle. First to two points wins — a mistake costs nothing, it just locks your keypad for the round.

Challenge a friend here, no app needed

A challenge between friends does not count towards the ranking: that one you play for the face he will pull.

Against the world

Show the world who the puzzle king is.

Win one and you climb. Lose one and you drop — but for the puzzle king, losing is not up for discussion. A worldwide board, a friends board, and your head-to-head with every one of them, duel after duel.

  • An opponent at your level, found in seconds
  • Every Monday, the week’s podium wins coins

Difficulty

Choose what you want to prove.

Easy, Normal, Expert. You never face anyone who chose something other than you.

Easy +20 “I want to prove I am the fastest.”
Normal +40 “Standard difficulty, for anyone who likes puzzles.”
Expert +80 “For people who really like to think.”

The coins shown are what a ranked win pays. Even a loss pays something: a duel lost is still a duel played.
