MLK Day Hidoku Logic Puzzles

For years, I have used hidoku puzzles in my classroom, and they have always been a HUGE hit with students. I recently learned how to generate shaped hidoku puzzles.

Have a different shape of puzzle your students might be interested? Send me an email, and I might be able to make it happen!

This puzzle is just one of many printable hidoku logic puzzles that I have created for my own classroom and am sharing with you!

I also created a MLK Day Maze that you might be interested in.

What are Hidoku Puzzles?

Hidoku Puzzles (or Hidoku Puzzles) are the creation of Dr. Gyora M. Benedek, an Israeli mathematician. The Hebrew word “hida” means riddle. In a hidoku puzzle, you are given a grid with a selection of the numbers already filled in.

Your task is to fill in the missing numbers so that each number connects to the next number either horizontally, vertically, or diagonally. 1 must connect to 2, 2 must connect to 3, and so on.

When I use Hidoku Puzzles with students, I often have them draw in the lines between the numbers in order to help them check their solutions.

Fill in the missing numbers in the letter-shaped grids so that each number connects to the next number either horizontally, vertically, or diagonally.

This Martin Luther King Jr Day puzzle is actually six hidoku puzzles in one!

You could definitely think of this puzzle as making a “chain of numbers.”

Four Levels of Puzzles and Printing Options

These MLK Day logic puzzles are available to download in four different levels: Easy, Medium, Hard, and Challenging.

As the levels progress, you are given fewer and fewer numbers on the grid to begin with. This means that much more logic is required to solve the puzzle.

For most students, I would recommend starting with an easy level puzzle unless your students have solved numerous hidoku puzzles in the past.
