You cannot save Skippies for future use. If you want to claim a Bonus tied to an ad, the available Skip will be used automatically. This includes all ad videos for claiming bonuses or those you can watch at your discretion.

Skippies are an option that allows you to easily claim your bonuses. You immediately receive your coins without having to watch ads. If you have Skippies in your account, when you choose to claim a bonus tied to watching a video, pressing the "collect" button will immediately give you your reward and skip the ad.

This includes all ad videos for collecting bonuses or those you can choose to watch. Ads that appear during the game or immediately after are not affected by Skippies. To avoid in-game ads, you need to have a VIP subscription. You can learn more about the different types of ads in the game HERE!
