Hello @marianngerwig and welcome to our Community!! I'd love to assist you here. Are you playing Pyramid Solitaire Saga on a mobile device or on a computer?
Unfortunately, I cannot tell you how long it will take to see new Pyramid Solitaire Saga levels for PC; however, if you can download the app on a mobile device -a phone or a tablet- you'll be able to play many more fun levels
I hope you can continue with your adventurous quest!!
