CaiCai - The Guessing Game

One question, everyone guesses: closest one wins. Over 1,000 sourced questions, plus a new one every day for the whole world.

How many nails hold a Euro pallet together? How long did the deep-sea octopus guard her eggs? Nobody knows exactly – and that's the game.

Guess. Gasp. Debate. CaiCai is the guessing game for the dinner table: one question, everyone estimates a number, closest guess wins the round. Then Mo cracks the fortune cookie and the real answer fuels the debate until dessert.

PLAY WITH YOUR FRIENDS' PHONES – Create a round, put the QR code on the table, everyone joins in their browser. No download, no sign-up. CaiCai scores automatically.

QUESTIONS FROM YOUR INTERESTS – Everyone secretly picks topics; the mix is built from all of them.

1000+ VERIFIED QUESTIONS – Twelve topic worlds, every answer an exact, sourced value with a story worth reading out loud.

ONE QUESTION A DAY, FOR THE WHOLE WORLD – The daily question is the same everywhere. Guess, marvel, and see how close you came compared to the rest of the world – with streaks and an archive.

SOLO TOO – You against the questions, with points, streaks and a personal best.
