Just to leave some suggestions of puzzle games that are little hidden gems and that provide great logic thinking training. IMO they should be played in the order below:

1) Blockly Maze game (free) (https://blockly-games.appspot.com/maze?lang=en)

2) Jelly no Puzzle (free) (http://qrostar.skr.jp/index.cgi?page=jelly&lang=en)

3) Human Resource Machine (paid) (http://tomorrowcorporation.com/humanresourcemachine)
