"Capture and Return" is a capture-the-flag game that you play against AI opponents in a randomly generated arena. There are 6 skill levels, however only the easiest skill level is available in the free trial version. There is also a paid version in Google Play ( https://play.google.com/store/apps/details?id=fi.hoopoa.captureandreturnfull ). Strategic thinking is required in how to block the enemy effectively without getting blocked yourself. Of course, luck and the random aspect of the levels play a role in how often you win, in addition to your skill and experience.
