Every match tells a true story

Mahjongg solitaire with something to read. Clear the board two tiles at a time, and every pair you match opens a short story about your subject, checked against its sources before it ever reached a tile.

Twenty-four tiles from Baseball, on the Pyramid stack.

Pick a subject

3 subjects are ready to play, each one four suits of nine stories. Another 149 are being researched.

How a game works

  1. Choose a subject and a stack

    Pick what you want to read about, how the tiles are stacked and how many of them there are, from a 24-tile quick game to a 216-tile marathon.

  2. Match two free tiles

    A tile is free when nothing sits on top of it and its left or right side is open. Two free tiles showing the same picture come off the board together.

  3. Read what the pair opens

    Each match tells you the story behind that tile. Stories you have not seen before are saved to your collection, so the next game deals you new ones first.

Where the stories come from

Every story starts as research with sources attached. It then goes to separate checkers whose instruction is to refute it: each one keeps, corrects or cuts it, a correction has to be confirmed by a different checker, and anything that cannot be confirmed is dropped. Research and checking are done by AI agents working to a written standard, and a program applies their verdicts, so nothing reaches a tile because someone liked the sound of it.

Each subject page shows how many stories were considered and how many were cut. Read the whole process.
