Hi there!
If you have picked play online when you logged into Foldit (the smiley face button), you are already playing online!
The next menu you should see when you log in is the "main menu".
The tutorials are in the "Intro Puzzles". Simply click on the button, then click on the tutorial you want to play.
The other puzzles are "science puzzles". Simply click on the button, click on the puzzle to highlight it, and click the smile button (Play).
To reach this menu from a puzzle you are playing, go to the "menu" tab at the bottom of your screen and pick "puzzle menu".
I need better instructions on how to find the puzzles with tutorials and how to start a puzzle. I can get to the description of the puzzle but there is no start button. Do I need to download each puzzle?
I did a few but can't find the way to do it again. There is no tab for Play Online when I log on.
