How to play Quadlink

Quadlink is a daily logic puzzle where you link four related items into four groups. Each day brings a new challenge!

Here’s how it works:

You’ll see a grid of 16 words or clues.
Select four you think may be linked and press submit.
Each correct group is removed from the grid.
Continue until all four sets are found — or you run out of guesses.
In Hard Mode, after three correct sets are found, you must type in what links the remaining four. It doesnt have to be exact, just in the ballpark.
You can have up to six wrong guesses. Good luck!
