You can get rewards for watching video ads. There are several places in the game where you can do so:
Boxy
Boxy appears on the main game screen at team level 18:
Every day, Boxy shows ten video ads. You get various rewards for watching them. You get five videos at 5:00 AM your local time and five more at 5:00 PM.
Theater
The Theater unlocks once you complete the tutorial. You can find it by tapping Merchant on the main game screen.
At the Theater, you can watch video ads to get Tickets. You can spend Tickets to buy energy, Raid Tickets, emeralds, and gold. You can earn up to eight Tickets daily.
Keep in mind that you cannot refresh the Theater, and goods are always the same.
Expedition
You can find expeditions on the Airship. To start this expedition, you need to watch a video ad. The expedition lasts six hours and does not require heroes. It also has a unique icon on the map:
Exchange Shop
You can watch a video at the Exchange Shop every eight hours and get gold without spending emeralds. This exchange also counts in the progress of daily quests to use Emerald Exchange. But it neither reduces the number of Emerald Exchange attempts nor increases the number of emeralds needed for an exchange.
Hero Skill Points
You need Skill Points to level up hero skills. After you use Points, it takes time for them to restore: you get one Point every five minutes. You can get a maximum of 20 Skill Points this way.
You can also receive Skill Points by:
- spending emeralds;
- watching a video ad every eight hours.
For each video, you get 10 Skill Points for free.
Note
There is no limit to how many Skill Points you can get for watching videos or spending emeralds. Thus, you can have more than 20 Skill Points available at a time.
