Your time is valuable. If you have something more profitable to do with your time than to play a game, thats great. But if you have some downtime and you want to do something better than destroy zombies, then consider challenging yourself with Rotopath.
I am committed to providing worthwhile options for you. Rotopath is one option that provides plenty of mental stimulation. It has 6 levels of difficulty to accommodate all levels of strategic thinkers. I keep leaderboards on Game Center, so that you can track your improvement and see how you compare to other Rotopathians worldwide. Millions of puzzle combinations (Can you calculate how many?) means youll have unique challenges as long as you want to play.
