Trivia Pass is a feature in which you can get incredible prizes by answering questions correctly in Classic Mode, Daily Challenge, Tower Duel, and Events.
As soon as you enter, you will see a board with different levels; within each level, you will see the necessary amount of correct answers to get to the next level. Next to each of them, you will see the prize that you’ll get if you pass it; the more levels you pass, the better prizes you’ll receive.
Once you reach level 29, you’ll have the chance to unlock a special chest.
If you want to get better prizes, you can acquire the Trivia Pass, by getting the VIP Membership.
