Do you want to train your mind? Here’s a nice puzzle game where you need to complete a path : Arrow Path
The main screen let you choose to play the game, to enable audio and music (very nice background music) and to access to Google Play Services to check the leaderboards.
If you choose Play you can play several levels, but you need to choose difficulty first.
I suggest to try very easy to learn how to play it. There are over 800 levels available.
The target of the game is to complete the path by dragging the arrows at the bottom over the empty spaces on the board.
If you make a mistake you can move an arrow over another one to switch position.
I think this game is well done and challenging after you complete the first few levels.
