Divide the class at least into 3 groups. Students in the groups try to ask Wh- questions and answer their questions. If their sentences are right they click on the square corresponding their answers. Under the squares if a heart appears their group gets a life, if it is a skull they lose a life and if it is a gun they shoot one life from any group they want. Students love this game and they try to produce correct sentences.
You can use any tense to ask questions.
