Each day, you will be given a daily mission with in-game objectives. Once you reach these objectives you can turn in your mission for XP.
When turning in the mission you can choose to boost the XP you receive by watching an ad.
You can have up to three daily missions at the same time, and once all of the missions are completed, you will be given one new mission per day.
Weekly Challenges is a totally new feature that requires the players to complete 15 Daily Missions within a week and the Challenge rewards 20 000 XP (which cannot be boosted with Ads).
New Weekly Challenge appears each Monday at 07:00 UTC and you have exactly one week to complete it.
You can not get progression to Weekly Challenges or Daily Missions from Custom Games!
