I don't often associate mazes with being in a state of zen (the film Labyrinth comes to mind). However, Maze Zen is the exception.
Rolling through mazes has never been so therapeutic! You can even unlock extra-sensory skills in 'Master Zen' mode where you navigate with your eyes closed. Trust me, If you ever need to wind down, this app is the key. See if you can keep your cool by downloading this beautifully designed app that was originally $3.99 but is now FREE!
