On This Day

The history quiz that drops you inside the moment

2 followers

History games usually feel like exams. On This Day feels like being there. Each day you get 10 scenes richly written, present-tense. You're placed inside a moment 10 seconds before a pivotal event in history. Then you're asked: what happens next? Four choices. One correct answer. What makes it different: - The writing is cinematic, not dry. Each scene is crafted to make you feel the tension. - It's daily and free. 10 new moments every day. Built solo, vibe-coded on Replit.
