I have added two new games about idioms and adages to the growing supply of word games on alphaDictionary. The first consists in matching idioms and adages with an prose description comprising arcane vocabulary, e.g. neophyte serendipity = beginner’s luck: http://www.alphadictionary.com/fun/idiom_match.html
The other new game–my favorite–is matching idioms and adages with a picture of their literal meaning. For example, a picture of people climbing walls = climbing the walls. It may be found at http://www.alphadictionary.com/fun/idioms_adages.html.
