Welcome to the community @rosefel! You are obviously with the group of people that have to wait for 30 new levels every week. Congratulations. As @RumellKhan123 mentions, you can use the remaining time until next Wednesday to collect Sugar drops/boosters (if you have them), and participate in other events that help you get boosters (like the daily calendar and spin the wheel) and if you have it - the daily quests. Not everyone has access to the same 'extra' things that allow you to collect boosters, but what you do have access to - that is a great way to spend a little time each day in preparation for the new levels on Wednesdays. Happy Crushing!
I do play and signed in everday to gain more boosters. I have also went back to those levels that I have only gained 1 stars hahhaha just for fun...thank you guys . Now I know that it is every wednesday for the new levels to come out, well I guess I just have to wait or utilise the 30 levels in a week... 😊😊😊😍😍😍
