Speed Math

Inspiration

Quick, short-form interactions are now a natural part of online communities. People enjoy fast feedback, lightweight engagement, and moments of excitement. We saw an opportunity to use that same rhythm to create something that actively engages the mind.

Instead of changing how users interact, Speed Math builds on what already works — brief, high-energy moments — and turns them into one minute of focus, speed, and problem-solving. By combining the appeal of short formats with competitive math, we aim to make mental engagement feel just as intuitive and enjoyable as participating in any subreddit.

What it does

Speed Math challenges users to solve as many math problems as possible in one minute. Players start a 60-second round. Questions appear one at a time. Each correct answer increases the score. Speed and accuracy determine performance. Users compare results with others in the subreddit.

How we built it

Speed Math was built using Reddit’s Devvit framework.

Challenges we ran into

How to build the game was a core thought. Earlier we thought about random questions but we miss the aspect of competing with others. So we decided to generate fixed set of questions for each instance. Those would be applicable for all users bringing everybody on the same platform.

Accomplishments that we're proud of

Built a playable game experience entirely inside a subreddit using Devvit. Created a true micro-challenge loop: play → score → compare. Turned short interactions into moments of focus and competition. Designed a system that’s simple, fast, and engaging. Delivered a concept where math feels like a sport, not a task.
