Number search puzzle to activate and engage the working memory muscles of the brain. The brain needs to hold the 6-digit sequence of numbers in short term memory, while scanning the puzzle grid to locate the hidden number. Complete the puzzle using either the PDF format or the Google Apps format.
The brain works by comparing what is in its short term memory with the numbers sequenced in the grid, and when there is a 'lock', or when the brain recognizes the sequence, circle the digits and record that number as located. Just like finding a word in a word search puzzle. Choose either the PDF or Google Apps version to complete the puzzle.
