Numbrix puzzles are logic-based number puzzles where a user has to connect consecutive numbers in a grid vertically and horizontally. Depending on the size of the grid, the numbers have to be in order from one to 100.
Numbrix puzzles require logical deductions by the analyzing of possibilities for each number or cell within the puzzle. The user must connect the numbers one to 100 only by vertical or horizontal means. Often, the user has to move through the puzzle out of sequential order to solve it correctly. Numbrix puzzles were created by Marilyn vos Savant and hold similarities to other puzzles, notably Hidato, where the only difference is that the numbers can be arranged in a diagonal as well.
