Letter Shift is a game (not only) for children. The aim of the game is
to put unarranged letters in alphabetical order.
It seems simple, but it can be very difficult. This depends on how often
the letters are shuffled. The most difficult game results from an input
between 30 to 50.
How to move the letters:
~~~~~~~~~~~~~~~~~~~~~~~~
One field on the board is emtpy. A neighbouring letter (vertical
or horizontal) can be set on the empty field by typing it in.
The computer doesn't allow non-existing or non-neighbouring letters
to be moved.
Example:
~~~~~~~~
Board: (3 times shuffled)
+---+---+---+---+
║ A ║ B ║ C ║ D ║
+---+---+---+---+
║ E ║ F ║ G ║ H ║
+---+---+---+---+
║ I ║ J ║ L ║ ║
+---+---+---+---+
║ M ║ N ║ K ║ O ║
+---+---+---+---+
Input: L
Board:
+---+---+---+---+
║ A ║ B ║ C ║ D ║
+---+---+---+---+
║ E ║ F ║ G ║ H ║
+---+---+---+---+
║ I ║ J ║ ║ L ║
+---+---+---+---+
║ M ║ N ║ K ║ O ║
+---+---+---+---+
Input: K
Board:
+---+---+---+---+
║ A ║ B ║ C ║ D ║
+---+---+---+---+
║ E ║ F ║ G ║ H ║
+---+---+---+---+
║ I ║ J ║ K ║ L ║
+---+---+---+---+
║ M ║ N ║ ║ O ║
+---+---+---+---+
Input: O
Board:
+---+---+---+---+
║ A ║ B ║ C ║ D ║
+---+---+---+---+
║ E ║ F ║ G ║ H ║
+---+---+---+---+
║ I ║ J ║ K ║ L ║
+---+---+---+---+
║ M ║ N ║ O ║ ║ <- this field must be empty !
+---+---+---+---+
Now the riddle is solved !
Enjoy
Letter Shift !
