What is Squaqq and Who is Felix?
Allie, Blake, Cliff, Derek, Ethan and Felix were the participants in the first (and last) annual Squaqq tournament held in the Mathematics Common Room. The idea was that whenever two of the participants were in the Common Room at the same time, they played a (single) game of Squaqq. And on the first day, that is exactly what happened. Each of the participants entered the room exactly once, stayed for a while, played every participant they encountered there and left. All times of entry and exit from the Common Room were different. The participants all turned in score sheets, but only recorded their wins (there are no draws in Squaqq). Here were the results claimed on those score sheets.
Allie beat Blake and Ethan. Blake beat Felix. Cliff beat Derek and Felix. Derek beat Allie and Felix. Ethan beat Cliff and Blake. Felix beat Ethan.
- a) Gary agreed to keep track of the results. When he considered the score sheets from the first day along with the other information given above, he discovered that the scores sheets could not all be correct. How did he determine this?
- b) There was only one score sheet error. One participant had mistakenly included the results of a game that had happened the day before the tournament began. Which game was it?
