Questions, answered
Is BRINXO free?
Yes. BRINXO is free to play. The Android app may show an occasional ad between rounds — never during a question. The only thing for sale is an optional one-time Remove Ads purchase in the Android app; there are no subscriptions.
Do I need an account?
On this website and in the Android app, yes: BRINXO asks you to sign in once (with Google or a one-time e-mail link, no password) so your level, streaks and battle record are kept in your free profile on every device. After that, the solo modes also work offline on that device. On game portals such as CrazyGames, no BRINXO account is used. You can delete your account at any time — here’s how.
Can I play offline?
Yes, once the game has loaded. Open it in your browser while you are online; after that it starts and plays without a connection, and your progress stays on your device.
Is BRINXO available on Android?
What game modes are available?
Five. Blitz: 60 seconds, as many as you can. Daily Challenge: twenty questions, new every day. Endless: timed questions that keep getting harder, three lives. Memory Grid: remember the lit tiles and tap them back. Target 24 — Number Forge: combine four numbers with + − × ÷ to make 24.
How does scoring work?
Each correct answer is worth 50 points, plus up to 50 for speed and 10 for each difficulty level above the first. That total is multiplied by your streak multiplier. A wrong answer scores nothing.
How do streaks work?
Correct answers in a row build a streak. Three in a row gives ×2, six gives ×3, nine gives ×4 and twelve gives ×5, the maximum. One wrong answer resets it. The Daily Challenge also counts a day streak for playing on consecutive days.
Does BRINXO have online multiplayer?
Yes. With a free profile you can add friends and play one-on-one battles.
Does BRINXO have global leaderboards?
Yes. With a free profile, your scores count on the daily and all-time boards.
Does it work on phones and school computers?
Yes. BRINXO is lightweight and works in modern browsers on phones, tablets, laptops and Chromebooks, with touch, mouse or keyboard.
