React event roulette is a simple yet effective way to test the reaction times of your app. You can use it to simulate the effect of a pizza delivery or a restaurant closing down. The idea behind the game is that members of a team share a photo of something they would rather not do. It could be a funny, cool, or even extreme picture. After the photo has been shared, everyone in the room must describe what the image depicts. This type of event is most suitable for teams with more experience.
