Another word game, in Russian this time:

.... or in English, if you choose, I think it has six different languages. Basically, it's a kind of crossword puzzle, except that the letters are mixed up, and you're supposed to put them in the right order to form an existing word.
I made it till about level 9-10 before I had to retort to pure guesswork...
Good fun though.
I wish there were a game like that, but for language learners, i.e. with a vocab list of the words used, and each level using a set of, say, 100 words, going from easy, everyday language, up to the more serious stuff (level 732 :P ). Playing the game over and over would be a good vocab drill......
