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).

The 4 Basic Rules of Numbricks


1. Fill in the missing numbers in the grids

numbrix rulesThe 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

how to solve numbrixThe 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

numbrix logic puzzlesThe 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
