Hi Username,
Lovatts make a whole range of crossword and puzzle books that are sold in the United Kingdom, New Zealand and Australia. They have regular competitions and the puzzles vary in the degree of difficulty.
You can visit their website for more information.
Just go to
www.lovatts.com.au
You can also access their daily online puzzles - just click on "The Puzzle Player" and it will take you there. The online puzzles don't have any competitions at this stage.
I have only ever done the Lovatts cryptics, so I am unable to give you a comparison on the styles, but someone else may be able to answer that part of the query for you.
Hope this was of some help.
Regards, Butterfly
