Unfortunately I found a bug in the Cookie system for storing puzzles. In any case it wasn't very useful
as you couldn't share puzzles.
In the new version, the box below contains your puzzles. When you save a puzzle, it will be added to the list.
Type a puzzle 'Word' into the box before the Load button, then click Load.
In order to save the puzzles, select the games below, copy them, ane paste them into a file.
To reload them, do the reverse and paste them back into the box.
