Unforseen Flaws

Posted by JG on May 25, 2011 – 6:41 am
A teacher was having trouble getting her students to learn their facts, but she noticed that her students often played the game “Rock, Paper, Scissors”. She made a game with similar rules in order to encourage the students to learn their facts.

The class would be divided into three teams: Rock, Paper and Scissors. The teacher would ask the students a question and the class would raise their hands if they knew the answer. If the first person to answer the question correctly is in the Rock team, he or she would choose one player from the Scissors team to be eliminated. Similarly, if a player from the Scissors team was first to answer the question, then he or she would eliminate a member from the Paper team. Lastly, if a player from the Paper team was first to answer correctly, he or she would eliminate a member from the Rock team.

The teacher would then continue asking questions until only one team still has members. That team would be declared the winner and all its members would win a small chocolate.

However, as soon as she explained the rules to the class, one particularly smart student immediately found a large flaw that made the game unplayable. Can you do the same?

If one team is completely eliminated than another team can’t choose who to eliminate next.

Example:
Scissors team is completely eliminated.
They can’t choose one member from Paper team to go out because Rock doesn’t beat Paper.

Let say the smartest team is the Rock team and each team has 5 players. They are so smart that they answer the first 5 questions correctly and therefore knock out all of the Scissors team. How do the players on the Paper team get eliminated then since all the Scissors are gone?

Similarly this would be true for any team which knocks out another team. There is no way for them to win.

I agree with John. As soon as you knock out the other team, you will basically be eliminated by default. If I were on one of these teams, I would try and answer incorrectly.

Good job. You got that quicker than I expected.

The best team would always lose and the second best would always win. If S was knocked out by R first, R would be the best team as they have got the most questions right. P (the second best team) can never be knocked out, but will eventually knock R out.

6. 6. Chris Said：

I goofed that last post. S or P could be the worst team.

If scissors eliminated paper, there would be no one to win over rock.

If rock eliminated scissors, there would be no one to win over paper.

If paper eliminated rock, there would be no one to win over scissors.
