Please don't cheat and tell others the code! Find the different code. once you find it push space and type in the letter and/or number. if it changes to the next one you got that one right. If you win I will follow you!
Note: Remember not to post the code here but in my profile. Hint for first one: Things may deceive Hint for second one: Look for the odd ones out Hint for the third one: Most things are useless
