When I spin the wheel used every day, something went unusual. There were some common booster probabilities and some uncommon ones. I spin the wheel only that
the jelly fish, color bomb, and the striped + wrapped were common when it land on and the lollipop hammer, free switch, and the lucky candy being uncommon to land in. The coconut wheel is in between.
I've rarely landed on a lucky candy slot of the wheel after at least a month of spinning a booster wheel.
