About the Game

A logic puzzle where you guess a number based on the sum and difference of numbers. The goal is for players to correctly guess 4 out of 10 numbers. Players cannot ask questions as they please; their questions are controlled by the use of question cards. Ask the right questions to narrow down the numbers.
