There are many Minesweeper clones for iOS devices, but Serenity Mobile’s Minesweeper – Widget Edition might be the most convenient version yet. As its name implies, it sits right on the Notification Center. That means it’s always just one swipe away, even from your device’s lock screen.
The game automatically saves and loads your progress and has customizable difficulty. Here’s a demo video courtesy of iPhoned:
Minesweeper – Widget Edition costs $1. Apple has a history of banning Notification Center widgets that do more than just notify, so if you’re interested in this game I suggest you grab it as soon as you can.
