I have a new feature called Magic Season where you win a prize after completing 5 levels. Then, after completing another set of 5 levels you get another booster. You can complete up to 20 tiers (100 levels) in the feature. At the end of tier 20, you can win a UFO.
How can players that are at the max level be able to complete 100 levels? The feature lasts 12 days - today 45 new levels were released, next Wednesday another 45. That is just 90 new levels, not enough to complete the 100 needed for the UFO!
