YC S25 · Real-Time Quiz Arena
BrainBolt
BrainBolt turns any room — office, classroom or conference hall — into a live game show where everyone plays from the device already in their hand.
// The Problem Quiz Nights Keep Dying Before They Start
Picture the last trivia session you joined: half the room stuck downloading an app, others giving up the moment a sign-up form asked for their email. By the time everyone finally gets in, the energy is gone. Most quiz tools were built for classrooms — designed around a single session, played once, then forgotten.
And when the game ends, everything ends with it. Scores vanish, teams scatter, and next week the organizer starts from zero. There's no simple way to keep a rivalry alive across weeks, or to reward the team that actually showed up every single time.
Worst of all, when scoring lags behind the shouting, the magic dies. A live quiz should feel like a game show — the answer lands, the score flips, the room erupts. If the leaderboard catches up ten seconds later, nobody cares anymore.
// The Payoff Everything a Great Quiz Night Needs
In the Game in 10 Seconds
No downloads, no accounts. Players just open a browser, tap in a 6-character code — or scan a QR code — from any phone, laptop or tablet and start answering.
Scores That Keep Up
Answers are scored in milliseconds and the leaderboard moves the instant a response arrives. Across the arena, answers come in after 0.84 seconds on average — and 92% of them are right.
Six Ways to Ask Anything
True/False, Multiple Choice, Image MCQ, Type Answer, Map Pin and a Closest Number slider — pictures for visual rounds, typing for recall, map pins for geography. Every round feels different.
You Run the Show
Advance questions manually or automatically, hide the leaderboard for suspense, control question reveals, mute the audience — and bring your questions in straight from a spreadsheet.
Rivalries That Actually Last
Team rosters and standings carry over between sessions. Run quick Solo Sprints, head-to-head Team Clashes, or multi-week League seasons with automated standings and prizes.
Start Free, Stay Flexible
The Spark plan costs UGX 0 and needs no credit card. Upgrade only when you need more players, more questions or full league structures — or simply pay per session. No annual subscription.
