Hi there! I understand you're finding the puzzle pieces in Jigsaw Puzzles Epic to be too large on your Mac. Let's get this sorted out together.

To start, can you tell me if you're able to adjust the difficulty level or if you've noticed any zoom settings within the app? Sometimes, higher difficulty levels or zoom functions can affect piece size.

Meanwhile, here’s a straightforward way to try resizing the pieces:

1. When you start a new puzzle, tap on the image you'd like to do. A settings window should pop up.
2. Look for an option related to puzzle piece size or difficulty — adjusting this can shrink or enlarge the pieces.
3. Also, check if there is a zoom feature turned on; turning it off can make pieces appear smaller.

If these options aren’t visible or don’t work, you might want to try closing and reopening the app or restarting your Mac, as sometimes reloading the app can reset display settings.

If you’ve already tried these or if the app doesn’t offer size controls, please let me know. I’ll help you with some deeper troubleshooting steps next.

Are you currently working on a particular puzzle difficulty or any custom settings you’ve applied? That info will help me guide you best!
