We apologize for the annoying ads. Like all popular mobile games, we play ads to support the teams. Hope you could understand that.
For Android, we do have options for ad removal. Click more offers in the SHOP, and you can find three options of NO ADS for you to purchase.
At present, there is no option to remove ads for IOS. We would try our best to add this function to the game as soon as possible. Sorry for the trouble!
