Who Am I? is a free daily football career path puzzle in which you identify a mystery player from the clubs they turned out for, revealed one rung at a time and ordered so the first clue gives least away. Guess whenever you like. Solving on the first club scores 100, and every further club you need costs 20. Guesses are unlimited, and a wrong one comes back with the reason it was wrong, so a bad answer still buys information. Trails are set at seventeen clubs across the top five European leagues over the ten seasons from 2016-17, though a trail names every club a player passed through, smaller ones included. A new trail is dealt at midnight UTC and everybody gets the same one.
You start at 100 and each clue you take off the trail costs 20. Solve on the first club and you keep the lot; solve on the fifth and you are down to 20. Guessing does not cost anything on its own, only the clues you reveal, so there is no reason to sit on a name you already suspect.
The board tells you why the name was wrong rather than just marking it. Guesses are unlimited, so a wrong answer that rules out a club or an era is worth making. It is only when you reveal the next club that the score moves — a run of wrong guesses on the same clue is free.
Puzzles are set at seventeen clubs across the top five European leagues, covered over ten seasons from 2016-17. That depth is what makes a trail readable; a club with three seasons of data produces clues nobody can solve. The trail itself is the player’s whole recorded career, so spells at smaller sides appear even though no puzzle is set there.
One completed round per game per day. There are three difficulty levels and playing any one of them marks Who Am I done until midnight UTC, when a fresh trail arrives. Difficulty is set by how well known the answer is, not by how many clubs are on the board. Older days are all in the archive.
The opening club is picked to give least away, so a loan or a youth side early in the trail is worth sitting on rather than spending twenty points on.
Transfer Trail asks the same question through moves and fees rather than clubs, and Team-mates does it through the people a player lined up beside.
