The Deutschen Schachjugend (a German organization for young chessplayers) has produced a booklet with several chess
variants, written in German.
You can find several of the variants from this booklet also on the Chess Variant pages. The webpage on the booklet tells a
price of 5 DM, which means it has not been updated since January 2002. 5 DM is approximately 2.50 euro's. The booklet is nicely
written and contains some nice illustrations.
