Here you can find some puzzles (just click) and if you want to have fun, try to solve them with the best time. 

 If you solve some (or each) of them,  take a screenshot  (where your time is visible). 

 Keep your scores (and pictures with screenshots) and consult with your teammates (in your team) to find out who has the best score (for puzzle No1, No2, No3).

 Send the screenshots to E.T. (with completed puzzle and visible time), but send only the best scores of your team (so maximum 3 messages from each team, subject for mails: YOUR_TEAMNAME Puzzle NoX)!

NB: if you don't follow the rules above mentioned, your scores won't be valid...
