Credits will give you the possibility of getting a second chance to answer a question. You'll be able to use them in classic games, Triviatopics and Survival.
When you answer for the first time in classic modes, you will be able to get a second chance by watching a promotional video if you have the ad version. When the next question is not answered correctly, you will be able to get this chance by using credits.
In Triviatopics you will be able to use credits to renew your tries in case you’ve run out of them in a specific category.
The game will initially give you 150 credits. You can get more credits playing Crown League or buying them at the store. There, you can see how many credits you have so far and the different packs the game offers.
In Survival, you'll be able to use credits to renew your attempts once you've used them up. Additionally, you'll have the possibility of using your credits to double the score generated in a game for the Weekly Ranking.
