Ciphers involve finding patterns in a problem and arriving at the answer; in this context, more complex rules are used.

You’ll combine various rules within a single puzzle—such as rearranging tables, paraphrasing words, and even considering the typeface in which the problem text is written—to unravel it.

The most important skill is the ability to notice what feels off in a problem, and from that intuition, search for the hidden rules.

To solve within the time limit, it may be crucial to rapidly test and apply different rules in your head—the speed of your ideas matters.

With the lighthearted tone of the story as well, let’s casually dive into the puzzle and give it a try.

First, solve the equations and draw lines connecting each equation to its correct answer.

Then, use that to figure out the letters that go in the blanks.

The key feature of this puzzle is that solving the equations alone won’t reveal the final answer.

The hint lies in the shapes formed by the lines that connect the equations to the answers.

Look closely—you’ll see a certain letter emerge.
