Fruit Ninja is extremely easy. There's only a few achievements that are bothersome but can easily be obtained if you put enough time into it.
The Oregon Trail is simple too. It only takes a few playthroughs if you're prepared and know what the achievements are. Each playthrough takes around an hour or so.
