Trivia Crack The game makes three power-ups available; three in the standard game and two in "challenge mode," which players can use to help answer a question. Using a power-up costs coins, and each power-up costs a different amount. Coins can be obtained by either the player purchasing them, winning them in challenges/standard games, obtaining them by reaching certain game milestones, or by using a prize card from a gem machine.
