How to hack HTML/JS games where you must guess numbers or passwords
Step 1: Get a Game
Step 2: Open Source of the Game!
right-click and select "View Page Source".
then search for the variable which you think is the number/etc you have to enter.
Step 3: Found It
we found a nice variable...
if we look at it, its a number between 0 and 1000, looks familiar... :-P
Step 4: Running Our Little Script
ok now press RETURN, and we get a new window.
it should tell us the variable's value.
enter the value into the input-box.
if it was the right variable, we should have won.
