Professor Layton and the Diabolical Box/Hint Coins

The careful detective will discover a large number of Hint Coins hidden throughout the game. There are a grand total of 230 Hint Coins scattered throughout the village; hidden in everything from barrels to rooftops. Hint Coins can be tricky to find, as you have to tap on the exact location where they are hidden. Be patient and follow the guide below to find them all. Hint Coins are used to buy hints on tricky puzzles. Each puzzle has three hits available for purchase, and using hints does not decrease the amount of Picarats awarded for a correct answer.

Beware! It is impossible to buy every hint in the game. There are some Hint Coins which can be missed, they will be marked red in the list.

An Interesting Note: The picture next to the Hint Coins changes as you save up Hint Coins.
