About the game

Daily Five

Five questions from different topics await you every day. Play solo, at your own pace, without creating a room. After each answer, you immediately see whether you were right and can read the explanation. At the end, you get five coloured squares and a view of your week. A new five unlocks every day at 3:00 a.m., Prague time.

Everyone gets the same questions that day, available in seven languages. Once you finish, you can send a short link to friends. When they accept, you connect and can see each other’s results after completing the five — on future days too. The connection is remembered in this browser and, once you log in, in your account on every device. If you spot an error in a question or answer, you can report it straight away.

Play with friends

CrazyBrain is a party quiz from Czechia for 2–8 players. The TV shows the game and phones are the controllers, or you play on phones only. Thousands of questions from dozens of categories and a quizmaster whose voice never runs out of one-liners.

• Speed: you score points for every right answer, and the faster, the more. The first to answer correctly gets an extra +300, second +200 and third +100. The final counts double.
• Themes: besides the mix of everything, 26 themed quizzes (Web design, European Union, Halloween, Czech Radio, Computing history, Fall of the Eastern Bloc, Friends, The Simpsons, US history, World War II, History of the Czech lands, Famous people worldwide, Czechia then and now, Film quiz, Famous Czech people, Sex and kinks, Fashion and beauty, The Lord of the Rings, Harry Potter, Food and drink, Music, Christmas and New Year, Czechoslovakia 1918–1992, Conspiracies, hoaxes and myths, Artificial intelligence, Dogs and pets). In the lobby you can also pick just your favourite categories — kids might want fairy tales only.
• Sabotage: bury your rivals in mud, ice or rats so they have to clean up before they can answer.
• For grown-ups: a cheeky quizmaster and, for the brave, Savage 18+ mode.
• For kids: kids' questions, kind one-liners and the Magic Brain, a joker that helps out once per game when things go wrong.
• Computer: one player short? Add a computer opponent.

How it works

• The game runs on our server, and the TV and phones keep a live connection to it. All you need is a browser and a stable internet connection, nothing to install.
• The easiest way to get it on a TV is an HDMI cable. No cable? In Chrome, menu ⋮ → Cast… → your TV with Chromecast or Google TV (source: tab, sound works too). On a Mac, via Control Centre → Screen Mirroring to Apple TV (AirPlay).
• The quizmaster's voice isn't made by us. Your browser speaks it using a voice that's already on your computer or phone. That's why voices differ from device to device and nothing gets downloaded.
