To use an Expert, tap on the "Hint" button that appears in the game scene. After spending Gems, your best-suited Expert will be automatically selected and will do one of the following:
- Eliminate one wrong answer
- Eliminate 2 wrong answers
- Reveal the correct answer
Experts are more likely to provide an efficient answer dependent on their Level and their Star rating for the particular Category.
Once an Expert has been used, it will be put on a cooldown timer and cannot be used again for four hours.
