You have 12 balls, and a weighing machine with no standard weighs. One of those 12 balls is either lighter or heavier than the others. Spot the ball in 3 chances with the weighing machine.

Thank you. I actually have spittle on my screen.Poop-Loops said:I've had that dream before. Kind of a nightmare, actually. It was impossible to walk or sit down.

Now if 4 against 4 doesn't cancel out, substitute one side with the remainder. Depending on what the scale reads, determine whether the foreign ball is lighter or heavier. In any case, you'll end with a 2 against 2 weighing, which will easily give away the foreign ball by swapping two balls from each side, and substituting for 1 ball from the remainder on one side.

The purpose of this challenge is to test your problem-solving skills and ability to think critically. It involves using a weighing scale to identify the odd ball among a set of identical-looking balls in only 3 chances.
The challenge starts with a set of identical-looking balls, with one being slightly lighter or heavier than the rest. Using a weighing scale, you must determine which ball is the odd one out in only 3 chances. Each time you weigh a set of balls, the scale will either tip to the left, right, or remain balanced, giving you a clue to the location of the odd ball.
The key to solving this challenge is to divide the balls into smaller groups and weigh them against each other. This will help narrow down the possible locations of the odd ball. Additionally, keeping track of the previous weighings can also aid in finding the odd ball in the remaining chances.
No, there is no specific number of balls required for this challenge. However, the more balls there are, the more challenging it will be to find the odd one out in only 3 chances.
No, the challenge specifically states that it must be solved in only 3 chances. This adds to the difficulty and requires critical thinking and problem-solving skills to successfully identify the odd ball.
