About Sumbo
Sumbo is a free real-time multiplayer trivia game you play in a browser with friends. Create a room, share the code, race to tap the right answer before the timer runs out. No accounts, no downloads, nothing to install.
Start a game →What Sumbo is
A multiple-choice trivia game built for groups. Up to six players join a single room from their own phones, tablets or computers. Each round shows a question and four answers; the faster you lock in the correct one, the more points you score, up to 20 a question. A match runs to ten questions, the final question is worth double, and the highest total wins.
The whole thing runs in the browser. There are no accounts, no sign-ups, no downloads, and nothing personal collected — just a name you pick for the game, which lives only for the length of that match.
How it works
One player opens Sumbo and creates a room. They get a short code to share — drop it in a group chat, message it, or read it out. Everyone else opens Sumbo, taps Join, and enters the code. Once the host hits Play, the same questions appear on every player's screen at the same time, and the race is on.
A typical match takes three to five minutes. Every question is timed, so the pace stays brisk, and a tap is final — there is no typing, no spelling, and no way to change your answer once it is locked in.
Where the questions come from
Sumbo's question bank is a mix of original questions written for the game and selected questions from the Open Trivia Database (opentdb.com) and OpenTriviaQA, both of which are licensed under Creative Commons Attribution-ShareAlike 4.0. Every imported question goes through a strict editorial pass before reaching the live bank — checks for ambiguous answers, weak distractors, factual doubt, dated answers, and party-game tone.
Questions span Movies & TV, Music, Geography, History, General Knowledge and Literature, with more packs surfacing as the content bank grows.
Where the images come from
The hero photos on each news-quiz question come from a mix of free and openly-licensed sources, selected per question by an entity-routed resolver that picks the right provider for the kind of thing being shown (a person, a film, a place, a company logo, an astronomical object).
Wikipedia and Wikimedia Commons for people, places, events, music albums, sports clubs and creative works (films, plays, books). Most are Creative Commons; sports-team crests and book/film covers fall under fair-use for editorial reference.
TMDB (themoviedb.org) for actor portraits and film and TV imagery. This product uses the TMDB API but is not endorsed or certified by TMDB.
Pexels for atmospheric stock photos, used as a fallback when no specific subject image is available. Photographers are credited at source on pexels.com.
RAWG for video-game cover art and screenshots, NASA Image Library for spacecraft and astronomical imagery (public domain), and Brandfetch for company logos.
Pre-answer, most images are deliberately blurred and tinted so the photo itself does not give the answer away. Once you answer the question, the photo sharpens to its full-colour reveal — part of the "guess, then know" loop the quiz is built around.
