Correct!
When you solve a puzzle correctly, you'll receive picarats equal to the number displayed at the
start of the puzzle. Sometimes, you'll also get an item, or a hint to help you with your investigation! Puzzles you successfully complete are sent to your Puzzle Index, allowing you to replay them at any time (p. 11).
Incorrect...
When you answer a puzzle incorrectly, you have the option to try it again straight away. You can also choose to view hints by spending hint coins, or simply quit the puzzle and leave it for later. Giving an incorrect answer means you will receive fewer picarats when you eventually solve the puzzle.
