My teachers didnt want a bomb game so I first reviewed all the key expressions and then gave them the cards. 
I cut the cards before hand.  Teams of 4.  1st had them find all matches.  Then they picked 10 pairs for their team and played memory with it.  I played where all the pictures/words are down and if you flip  2 cards over and they match then they are your point.  If they dont match then you put them back and its not a point.  You could also play go fish or old maid.  The winner I gave a stamp. 

After the cards I played hot seat or speed quiz --
1st round hobbies- making sure they got ~ing endings because this was the hardest for my kids to get. 
2nd round  people and what they are like.
3rd round can you-  same words as the first but with out ~ing endings

*I think everyone plays this different this is how I like to do it :)  I like to do 1 min rounds.  make teams there  is one person in the front with their back to the screen, they shouldnt see the screen.  Their team can use english hints or body language to help the person guess the word.  I dont allow Korean.  If they get the word then they sit back down and a new person from their team comes up and i change the word.  Every right word is a point for the team.
