CaiCai - The Guessing Game

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.

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