The next time you sit down for a riveting game of Guess Who with one of your younger family members, you can win 96 per cent of the time with this mathematical approach.
In this video from Mark Rober's YouTube channel, Rober explains the absolute best strategy for playing the popular 80s board game. The whole video documents how Rober came up with the strategy, and even how he confirmed it by having a buddy run it through a computer simulation.
Here's the gist of the strategy, though: stick to very broad yes or no questions that can knock out around half of the people every turn. For example, you wouldn't want to ask if their character's name rhymes with "Bow" because that only applies to one character, Joe.
Instead, you want to take notice of the characters' specific physical attributes. Upon closer inspection, you'll see that every attribute has exactly five characters that have that attribute. There are five characters with black hair, five characters with glasses, five characters with big noses, etc. Then, you finagle your way around the rules of the game by turning three questions into the one question you get per turn: "Does your character have red hair, or glasses, or a big nose?"
It's a little sketchy, sure, but if you do "Championship Play", which is just the first player to win five rounds wins it all, you'll be the victor 96 per cent of the time you play... assuming they aren't using the same strategy.
