The goal is to find matching pairs for all of the tiles.
Click one of the buttons at the top of the screen to select the size of the tiles.
You can also use the Zoom function, if your browser supports it.
Note that the puzzle works in both portrait and landscape modes,
and on PC, tablet, and mobile devices.
On smaller screens, landscape mode is recommended.
To start, turn over any two tiles.
If they match, they'll stay visible. If not, they'll flip back over.
Remember what was on each tile and continue matching tiles.
The game is over when you've matched all the tiles.
To shuffle the tiles and start a new puzzle, click Shuffle/Start a New Puzzle.
Note that each time you play, the tiles are shuffled, so the puzzle is different.
