+Summary:      Minehunter, easy to play, easy to enjoy
+Description:  |
+  Simple Minehunter Game:
+
+  This simple and classic MineHunter game is aimed for kids (but not only).
+
+  If you can read digits, you can play!
+
+  With a deliberately limited number of game options, everyone can understand how to play and how to adapt this game to his needs.
+
+  You can choose:
+  #   difficulty (number of mines): beginner, easy, medium, hard
+  #   size: 10x10 (very easy, for kids), 15x15 (easy), 20x20 (standard)
+
+  Mines as set after the first guess, you can't walk on a mine on your first move.
