Daily quests are activities that players can do to get rewards. Each daily quest will have a different requirement and reward. The number of daily quests will be refreshed after 24 hours at 08:00 UTC, with a certain amount depending on the quantity of doge you own at the time of reset. If you purchase more doges on that day, you must wait until the next day's reset.
Each completed daily quest turns one tile blue at the horizontal rewards road. You get rewards when you complete enough daily quests.
