Today's Free App of the Day is Pathogen
Originally $2.99

Apparently this game is a variation of Othello/Reversi. It's a beautiful game. The game is played in "campaigns." Think levels.

You start with the tutorial campaign. You have various kinds of pieces that you can play next to or on top of other pieces of your own. Different pieces result in transforming your own pieces or transforming enemy pieces, creating the strategy. I'm stuck on level four right now.

You can turn music, sound and animations off using the settings gear menu. You can create your own starting maps using the editor. You can choose the campaign difficulty if you go into single player mode. You can undo your last move anytime while the game is still active. You can earn achievements.

There are concerns by some reviewers about spyware; one top reviewer recommends playing in airplane mode or behind a firewall. Doing so will result in not being able to play against online opponents.

It does take a little while to install and load, if space is a concern for your device.

Plays in landscape mode, will rotate 180 degrees in case your cover or need to charge makes that important. As I typically do not play against online opponents, I am fine playing this in Airplane mode. I would give it four stars; five if they get rid of the reported spyware.

8 of 12 reviews are four stars and above.
