Lettris is a curious tetris-clone game where all the bricks have the same square shape but different content. Each square carries a letter. To make squares disappear and save space for other squares you have to assemble English words (left, right, up, down) from the falling squares.
Boggle gives you 3 minutes to find as many words (3 letters or more) as you can in a grid of 16 letters. You can also try the grid of 16 letters. Letters must be adjacent and longer words score better. See if you can get into the grid Hall of Fame !

A Monolingual learner's dictionary (or MLD) is a type of dictionary designed to meet the reference needs of people learning a foreign language. MLDs are based on the premise that language-learners should progress from a bilingual dictionary to a monolingual one as they become more proficient in their target language, but that general-purpose dictionaries (aimed at native speakers) are inappropriate for their needs. Dictionaries for learners include a great deal of information on grammar, usage, common errors, collocation, and pragmatics, which is largely missing from standard dictionaries because native speakers tend to know these aspects of language intuitively. And while the definitions in standard dictionaries are often written in difficult language, those in a monolingual learner’s dictionary aim to be simple and accessible.
Monolingual learner's dictionaries have been produced for learners of several languages, including German, Spanish, Dutch, and Chinese. But most of the activity in this field is in the area of dictionaries for people learning English. The first English MLD, published in 1935, was the New Method English Dictionary by Michael West and James Endicott, a small dictionary using a restricted defining vocabulary of just 1490 words. Since the end of World War Two, the MLD has been a publishing phenomenon, with global sales running into tens of millions of copies, reflecting the boom in the English language teaching industry.
Probably the best-known English monolingual dictionary for advanced learners is the Oxford Advanced Learner's Dictionary. now in its eighth edition. It was originally published in Japan in 1942 as The Idiomatic and Syntactic Dictionary of English, written by A. S. Hornby and two collaborators. It was subsequently republished as A Learner's Dictionary of Current English in 1948, before acquiring its current name.
Other publishers gradually entered the market. The Longman Dictionary of Contemporary English was published in 1978, and its most striking feature was the use of a restricted defining vocabulary, which is now a standard feature of learners' dictionaries. There are currently six major MLDs for advanced learners. In addition to the Oxford and Longman dictionaries, these are:
All of these dictionaries are available in hard copy and online.
Since the 1980s, the English MLD has, arguably, been the most innovative area in the field of lexicography, in terms of both the way dictionaries are written and the aspects of language which dictionaries describe. Notable advances include:
Monolingual learner's dictionaries have also been the subject of a great deal of research into how people use dictionaries, and are probably the most intensively-studied type of dictionary.
