Outlier is a browser based trivia game built around finding uncommon but valid answers. Each prompt asks players to name something that fits a category or clue, such as a river, a dog breed, or a country containing a particular letter. Answers are graded according to their rarity in a ranked list: common answers earn less distance, while rarer answers earn more. Each prompt also has a selected “gem” answer that receives the highest grade. The game is independent and uses its own prompts and answer lists. In unlimited mode, prompts continue until the player ends the run. Grades of A or S in consecutive answers build a hot streak that adds bonus distance, and the player’s UFO completes a lap every 700 kilometers. At the end of a run, the game displays total distance and average distance per prompt, with an option to share results as an emoji grid. Players can choose from seven themed packs, including geography, sports, movies and television, animals, food, science, and things and words. Outlier also offers a daily puzzle with the same seven prompts for all players. A typical session involves reading a prompt, submitting one answer, reviewing its grade, and choosing whether to continue or end the run. The game accepts some alternate names and spelling variations, skips recently seen prompts where possible, and can be played without an account or paywall. It runs in a web browser and requires JavaScript for gameplay; game statistics are saved in the player’s browser.
