On over 5,000 but my family wants to start a group together all at level 1. I know that I can still play the early games, but can I keep them separate?
Yes, but to create another account you need a different email address to the one you are using now.
Alternatively there is nothing stopping you from scrolling back to level 1 and just replaying the levels. It does not effect your progress @vickyeaston1234
