Sixteen terms. Four groups of four. Find the connection.

How to play

Sort the sixteen terms into four groups of four. Select four tiles, then check the group.

Each group sits at a tier from 1 to 4. Tier 1 is the gentlest, Tier 4 the meanest. You find out which tier you hit only once the group is right.

Get three of the four and you'll be told you're one off. You won't be told which one.

Four wrong guesses ends the grid and reveals the answers.

Several terms are placed to look like they belong somewhere else. That's the puzzle, not a bug.

The name stays after the thing goes

Plenty of the trade's working vocabulary describes objects that no longer exist. People still talk about a desk that has not existed since the agency merged, a tag retired two migrations ago, a report format nobody has opened since the platform rebuilt it. The old name survives because it is shorter than explaining what replaced it, and because the people who knew the original have mostly moved on. Newer colleagues learn the label without the history and use it perfectly well, right up to the moment the history matters. Then somebody has to dig out what the term once pointed at. Sorting these is a reminder that every tile on the board came from somewhere.
