Googling tells me there is a built-in hint system:
The Hint System: In the bottom corner of your screen, there is a hint button that you can use whenever you are stuck during the Hidden Object scenes or puzzles.Currency: Using a hint usually costs a small amount of in-game currency (often 5 coins per hint).
And then it directs me to a YouTube video
here to show me how the hint and coin system functions during gameplay. Maybe the YouTuber explains it more?
