Word Game is a simply named simple vocabulary and trivia game that you can play in your web browser. To play the game simply go to wordgame.betafactory.tech and you're into the game. The game consists of single questions that test your vocabulary and trivia knowledge. Only one question appears on the screen at a time. You do have to create an account if you want to save your scores and track your progress. Otherwise, it's completely free to play.
Word Game also offers a Chrome Extension that will display a new word and its definition whenever you open a new tab.
In the following video I provide a demonstration of Word Game and its corresponding Chrome extension.
