Welcome to the Professor Layton Illustrated Walkthrough
The puzzle list on the right lists the puzzles in numerical order while the next/previous links at the end of each page gives you the order that the puzzles are found in the game
Puzzle 12, for example, is not available until Chapter 4
On the right you'll also find lists of the gizmos, painting scraps, furniture and characters so if you're missing something then you can jump directly to where it can be found in the game
Live Chat is available through both CuppaJava and IRC (USA evening is usually the best time) and can be used to seek help, provide feedback, suggest other games for a walkthrough, chat with other players or just to say Hi
