What is your goal?
Are you asking a question verbally, having students buzz-in, and the first buzzer locks out the others?
How many devices are available? With one device, up to four players you could try "Game Buzzer" With a master device and individual devices you could try I Buzzed First *Costs $0.99 per device
I do not have Android-based devices, so I have not tried either of these apps, and cannot vouch for them. They were what I found in the Google Play Store.
If you are looking to have everyone in the room answer each question, there are a few different options. The following are all browser based, so they work on any platform:
Triventy Ask multiple choice questions, students respond on their device, Triventy awards points with the quickest correct response receiving the most. This system does not collect data at the end for the teacher to download and review student responses.
[Kahoot!](www.getkahoot.com) is the same as above, used by many teachers (and loved by teachers and students), but allows the teacher to download results as .xls or save to Google Drive.
[Socrative](www.socrative.com) lets the teacher make quizzes, do quick polls, or have a "Space Race" game.
Review Games was one of the things I really enjoyed doing in my classroom, I have a category of "Review Games and Tools" on my website, Teacher's Tech Toolbox
Hope that helps!
