As my previous post noted I was helping to organize a big competition for this weekend. That’s now happened. Major relief there. I still intend to get two Wednesday puzzles and a pack out this coming week.
Since this is a puzzle blog and not a math contest one, most of the rounds and problems are probably not of that much interest to you all (if I’m wrong about this, check here in a couple days). The exception is that one of the rounds which was unofficial and did not count for score was written to be sort of a hybrid between a math contest round and a mystery hunt style puzzle (although there’s no final answer word or anything). It ended up being way too hard and few teams picked up on any of the gimmicks, but that happens sometimes. Presuming you haven’t completely forgotten how to do math problems, you puzzle enthusiasts might fare better on it.
(The name mixer round has to do with how we shuffled teams before giving it out and has nothing to do with solving the round itself.)
As noted above, there’s no final answer; once you’ve answered all 12 problems you’re done. Feel free to email me for answer checking or hints or whatever. Or just wait until I get back to posting my usual content.
(Edit on March 14th: We’ve now posted solutions to all the rounds of the competition, including this one.)
