How do I complete clan quests?

To begin a clan quest, tap Clan Quest on the clan home screen. Your goal is to get the highest score possible. The total number of points you score on the board is multiplied by your multiplier.

Free attempts are available once an hour, but you can play more often for coins. Each new attempt costs twice the previous one.
There is a time limit for completing quests! If your clan doesn’t manage to score the required number of points in time, the current quest’s results will be reset.

You have 24 hours to complete each quest. If the quest is completed ahead of time and is scheduled to begin again in more than six hours, then a new quest will be launched in six hours. If the quest is completed ahead of time and is scheduled to begin again in fewer than six hours, then a new quest will be launched at the scheduled time.
