A game that was fun and successful is a variation on Go Fish, where students try to match cards with identical words written on them. That is, instead of asking if someone has any "Queens", the student asks a partner if (s)he has the word "PUB." If the student asked has the card with "PUB" written on it, (s)he gives the card to the student asking questions. If the student being asked does not have the word, "PUB", the other student must draw a card from stack of cards that were not passed out. Below is a photo of some of the cards I made up. I printed the words on an Avery label sheets. I stuck the words on old playing cards. You can often get these as give-aways from local casinos. Students liked playing with cards that looked like actual playing cards.
It is also possible to use these same cards to do vowel contrasts (e.g., "cap" and "cup"). When students had played a few round of Go Fish, they also could play a game of Concentration or Memory using the same cards or a subset of the cards. I also showed my students a link to an audio version of Concentration for practicing pronunciation.
