Our game offers a couple of different types of Hints to use if you're stuck:

Regular Hint (Light Bulb Button): Reveals the first letter of the next unfound word. Using multiple Hints will continue to reveal letters of the same word.
 
Mega Hint (Electric Light Bulb Button): Costs more than the other Hint options, but will reveal 5 random letters on the board.

Hints only work on required words.
