Hmm.

I might be late already but I'll tell you, there's no specific percentage for the drop rate of the 2 Jackpot Prizes in that event. Some people might get lucky and get one or both of them but not all players will be like that. Take me as an example, few people from my merged got one or both prizes and I tried. Spun the wheel until I reach the maximum milestone and got nothing. It's all up to you if you will try your luck but make sure that you are ready for any outcome that you might face. If you have the tendency to feel regrets after your actions that have a possibility of losses then you better keep away from that event.
