GeekDad Puzzle of the Week – Base 2 Number Find

Reading Time: 1 minute

number-find_teaserImagine set of 32 hexadecimal numbers, each with 8 digits. If we convert each hex digit as a four digit, base 2 number, we have a 32×32 grid of binary numbers. This is the perfect start of a number-find puzzle (like a word-find, but with numbers!)

Example: 1B8A42DE translates to 0001 1011 1000 1010 0100 0010 1101 1110.

Given the set of 32 hex numbers below, create the grid, and traverse it to find the eight 85s and the eight 170s present. Send their locations in an email to GeekDad Central for your chance at this week’s fabulous prize: a $50 Gift Certificate from our friends at ThinkGeek.

Note that standard word-grid rules apply, all numbers are 8-bit, and that binary numbers convert to decimal directionally, i.e., 00011011 and 11011000 are the same first 8 horizontal digits from different directions, but result in different base 10 numbers.

The set of 32 hex numbers that define the binary grid appear below:
