Microsoft Teams is a business communication platform built around a video-calling app similar to Skype and Zoom. Despite the fact that it's designed for enterprise customers, Games for Work is not the first gamey feature that was added to the service.
Games for Work is described as a "pilot app" whose future roadmap is about as far from set in stone as possible. Instead, its developers are hoping to use early user feedback to decide what kind of games, features, and changes to introduce moving forward. Besides Minesweeper and the iconic time-waster that is Microsoft Solitaire, the vanilla version of Games for Work also offers access to IceBreakers, a game designed to help players get to know one another through a series of this-or-that questions, followed by a quiz. There's also Wordament, a puzzler that rewards quick thinking and eloquence.
