RSG Puzzle of the Day

Today’s example, known broadly as a distance puzzle, is a type that shows up often at competitions. It again showed up in one of today’s individual rounds.

The instructions: Fill in the circles with different integers, starting with 1, such that each pair of consecutive integers is farther apart than the previous pair. (Hint: You’ll have to do a little time-traveling back to high school geometry and dust off that Pythagorean Theorem!)

Here is an example of a solved puzzle:

In honor of today’s National Sudoku Championship, today’s puzzle will be a sudoku. There’s a twist, though. This one’s called an “Arrow Sudoku,” and in this variation, each circled number is the sum of the numbers along the corresponding arrow path. (Otherwise, use the standard rules of sudoku.)

As always, answer to appear tomorrow in the comments thread.

As a storyteller and teacher, I’m partial to the puzzle below. It seems like the type of problem you could give to students of almost any age, and for classes ranging from creative-writing to math.

RSG Puzzle of the Day

We’ll start out with a (relatively) easy one.

The first question on the national qualifying test is usually a 10-point “Battleships” puzzle. Below is an example from the 1999 exam. (Answers to appear in the comments thread tomorrow.)

Locate the position of the 10-ship fleet (one battleship, two cruisers, three destroyers, and four submarines, as shown in the legend) in the grid. Each segment of a ship occupies a single cell. Ships do not touch each other, even diagonally. The numbers on the bottom and right edges of the grid reveal the total number of ship segments that appear in each respective row or column. Cells with water (indicated by tildes) do not contain ships. (For solving, ignore the letters and numbers on the top and left edges.) Answer key: Enter the location of the four submarines (i.e., the single-segment ships). Use the coordinates on the top and left edges to specify their places. For example, the given water locations are A4, F1, and H4.

A B C D E F G H I 1 ~ 2 2 2 3 3 4 ~ ~ 2 5 2 6 1 7 5 8 1 9 2 4 0 3 2 2 2 1 4 2
