Special candies can be activities alone?!

Yes, it's a fairly new feature that's been available for some months, but some only got it recently. Not everyone has it, and it's not necessarily permanent in your game. They rotate who gets what. A feature or game can be available to you for weeks, months, or years, then suddenly be gone or only available like 2-5 days a week.

Example, the Soda Race. I went from having it all the time, to only have it for 72 hours (through the weekend), to now only have it available for 48 hours every Friday/Saturday.

I also have the solo-booster feature currently, and it's awesome.

It really is. I am in the group who never had the ads option to get extra moves, so this was SO helpful. It still doesn't mean that you can easily get a level, but it sure helps some times.

I just passed lvl 14,000 but at level 13,220-something, I DID get the ads for extra moves help - for all of 10-12 minutes. It showed up in my game, and I was like OMG, FINALLY, I beat one hard level, then had to restart my game to get the latest cannon balls for Shipmates, aaaand it was gone again, never came back 🤣 At least it helped me beat that one level I was stuck on, but it also made me realize how *easy* some players have it. No wonder the people, who has had ads helps for months/years, complain when they suddenly lose that option.
