The European CW group, EuCW have launched a new on-air Snakes and Ladders, due to start on 1 April 2014.
For CW operators the game runs through from this April until the 31st of March 2015 on all HF bands. It is designed to promote activity on all bands and to encourage friendly contacts. It's not a contest; it's a game.
The Snakes and Ladders board is made up from a Maidenhead locator map of Europe and the position of each station after QSOs can go up thanks to a ladder or down when a snake bites.
Full rules are available in English and many European languages from the Snakes and Ladders web page - http://www.eucw.org/sl.html
