You may come across a puzzle that for some reason you decide not to play. Sometimes you might not like the theme (e.g. spiders!), or maybe you started it and it just wasn't fun. Fortunately there's a way to hide the puzzle so you don't see it anymore.
You can hide a puzzle by tapping the Edit button at the top of the home screen, tap on the Hide text for the puzzle(s) you wish to hide, then tap Done.
To unhide a puzzle(s), Tap the More button at the bottom of the home screen. Next, tap the Edit button at the top of the page. Tap on the Unhide text for the puzzle(s) you wish to unhide, then tap Done. They’ll be waiting for you on the main page, ready to play. Just tap the Puzzles button at the bottom to return to the Puzzle Gallery.
