Split your class into two teams. The first screen is the question link slide. Students choose a number (this is a template file with spaces for whatever grammar that you wish to add). Have the students raise hands to answer the question.
Within each slide, click the A circle to reveal the answer. Once a question has been correctly answered, click the G circle to go to the Tetris screen. Clicking the relevant coloured circle will trigger a block to drop. Clicking the "Q" icon will then take you back to the question selection slide.
This is a big template best suited for reviews. It takes a lot of work to unput the 36 question slides. I ended up just choosing a time limit or whenever interest started to wane, and the team with most Tetris lines at the end was the winner. This is an older game and doesn't look that polished, but my students were pleased with it.
I love tetris! This looks fun! Thanks for making it.
