Today's Free App of the Day is Mind Games Pro
This brain "training" game was the FAOTD back in January 2014.
It seems like concerns about adware have been addressed--current reviewers found no issues. It's a good game, though I think the instructions for the games could be a bit more clear and include an example--a couple of games it took me a couple rounds to figure out exactly what I was supposed to be doing. Or perhaps that's part of the test. :D

You can schedule a reminder to play a game.
The game quits cleaning using Quit on the main menu. It plays in airplane mode and can be played in any orientation.
