"Sniff As a Real Hacker" game is to find words, sentence in a character matrix, one matrix tile is ascii represent of one character.
For example, F ascii code is 46, O is 4F, X is 58. So to find "FOX", it is to find "46 4F 58" in actual.
The indirect finding needs great attention and patience as well, it is dull, but it is the dull which makes a real hacker.
Even you do not want to be a hacker, it is still a great way to train your focus and patience.
