What are Reactions and how do they work?

This is a feature in the Monopoly Go's emoji system. With reactions you can pre-set emojis to respond to other players' actions in the game.

To set up your Reactions, simply go to the settings section from your home screen (top right) and tap on My Showroom. From here, tap on the Emoji icon at the bottom and here you will be able to set your Reactions from any emojis you've earned.
