# What are Numbrix or Numbricks Puzzles

Numbrix is a great logic puzzle originally developed by a certain Marilyn Vos Savant o publishes these mind benders at Parade Magazine. Because Numbrix is a trademarked name, we developed printable Numbricks puzzles with the same rules and addictive character as the original Numbrix puzzles.

**The objective**of our Numbricks puzzles is to form a continuous path of numbers from 1 to the end numberof the puzzle. This end number depends on the grid size. A 5 by 5 puzzles, for example, has 25 cells, so the objective is to connect the numbers 1 to 25. The grids are already filled with some numbers and it's up to you to

**fill in the missing numbers**in such that they connect horizontally or vertically (see the rules).

Our printable Numbricks puzzles come in 4 difficulty level.

## The 4 Basic Rules of Numbricks

**1. Fill in the missing numbers in the grids**

The grids are divided into cells that are either contain a clue number or are empty. Sometimes you see circled number, this could be the 1 (the start number) or the end number. This end nuber can be 25, 36, 49, 64, 81, 100, 144 or 225, depending on the grid size (a grid of 10 by 10 contains 100 cells). You need to fill in the missing numbers in the empty cells.

**2. Connect numbers in a continuous loop or path**

The trick of this logic puzzle is to fill in all the missing numbers in such a way that all numbers in the grid are connected in a continuous loop. The numbers must form a chain, a path or a loop, whatever description you feel comfortable with. In our example on the left you can see that number 1 is connected to 2, 2 to 3, 3 to 4, etc....

**3. Numbers must connect horizontally or vertically**

The numbers in the grid must connect either horizontally or vertically. Diagonal connections are not allowed. The example on the left is wrong, the 3 and the 4 are

**diagonally connected**. This is not allowed in Numbrix or Numbricks. Are you stubborn enough to connect them anyway, we would like to advice you to print our Hidato-like puzzles, where this diagonal connection is possible.

**4. Each puzzle has only 1 solution**

Each puzzle is supposed to have 1 unique solution. Do you find any more possible number chains, please contact us. We will make our puzzle designer do 200 push-ups!

Numbricks is also known as Numbrix, which is a trademarked name. The logic puzzle looks a lot like the famous

**Hidato puzzle**, with the difference that in Hidato your are allowed to connect numbers vertically.

Our puzzles come in 4 difficulty levels (easy, medium, hard and stupendously hard) and in several grid formats/sizes: 5 by 5, 6 by 6, 7 by 7, 8 by 8, 9 by 9, 10 by 10, 12 by 12 and 15 by 15. If you are interested in publishing our puzzles (without our copyright), please don't hesitate to contact us so that we can create sets of puzzles for you.

Because our puzzles are in PDF form you can

**print them easily**and solve them wherever you are. They are also great for classroom purposes as postive reinforcements or activities for students. What's better than developing logic skills and boost our brains?
