Almost Always Win The Game Guess Who With This Maths-Based Strategy

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. You can learn more from the video above, and find more explanation at the YouTube link below. Now go win some silly games!

    So, cheat by asking three questions as one? Have I missed something?

      That's sounds about it. Pretty bad way of playing.

      The rules state the following;

      Each question must have either a “yes” or “no” answer.

      So technically the proposed question is valid.

      Yes - you have missed something.
      You have a fundamental misunderstanding of what this is about.

    Does he look like a bitch? Cos if you try to pull that sh*t at my house, you'll be slapped like a bitch

    By that f*$ up logic, why doesn't one just ask questionable questions like
    "is the person on the left side of the board"
    "is the person on the left side of the remaining characters"
    "is the person on the left side of the remaining characters"

    unless im mistaken (which i could be cause i only spend 30 seconds thinking of the dodgiest/boringist way) then in 3 questions you've narrowed it down to 3 people, possibly 2 people if your character is in the remaining 3

    If you want to inscrease the risk for possible better return, you could ask

    "is the person in the bottom row"
    yes - "is the person on the left side"
    - "is the person on the left side of remaining"

    if they are in row 1 then you end up with 2 people in 3 questions and if one of those is yours, you know who they are. if they are not

    Either way the game sucks even more when you play that way.

      I'm not 100% sure if it's the correct way, but all the games of Guess Who I've played have the characters laid out differently on the red and blue boards. This stops you being able to ask questions based on location, and you can also put your own character down at the start of the game without the other player knowing who you are.

        Hmm i guess thats probably true, i haven;t played guess who in 20+ years because its such a boring game.

    This game always sucked because you were always screwed if you picked a woman.
