Watch Ads is a feature on the main page where players can earn Gems by watching advertisements. Each advertisement gives the player a base amount of 68K Gems (although players can increase this amount through various passive abilities and achievements throughout the game). However, there’s a limit of only 5 advertisements players can watch a day, and they do not stack if players don't watch any advertisements over several days. The feature is available when the garrison reaches level 9, and players receive their Gems in their Mailbox.
At VIP level 1, players have the ability to skip all daily ads and get the Gems for free.
