To my mind,there are many games, but some games are for one level and other games for another one.Create them!

I use for warm up the next game. I give students cards with the words which we've already learnt. The cards are put on the desk face down. Student pulls card out and tries to explain this word using synonyms, making up sentences. The other student has to guess this word) And so on. )

Though I'm not a student, I can tell you about a game my students find helpful. It has different names, I call it "Memory Game". you need some pairs of cards (say 15) with the words you want your students to remember. they can be pairs of synonyms/antonyms, words in a foreign language and their translations, collocations and what not. so you put the cards onto a desk face down. a student picks up a card and has to translate the word/ give its synonym depending on what kind of cards you have. now his aim is to find a pair for his/her card. then he/she picks up another card. if the second card matches the first one, he/she goes on, if not he/she has to translate/give a synonym and so on and put the second card back and the turn goes to the next student. the winner is the person who has collected most pairs. During the game the students pick up the same cards so many times that they are sure to remember the words! I often use it - it really works! and students seem to enjoy it ))

I'm a visual learner, so I suppose anything that has some kind of graphic or illustration... diagrams maybe?

It depends on the lessons you teach.U can use a variety of games when teaching.U should find the best for special games.
