For players who need help or simply cannot solve a particular puzzle, there is a hint book in the library of the house.

The first two times the book is consulted about a puzzle, the book gives clues about how to solve the puzzle ; on the third time, the book simply completes the puzzle for the player so that the player can proceed through the game.

The Telegraph included it in 69th place in a list of " 100 novels everyone should read " in 2009, describing it as a " playful postmodernist puzzle ".

The original 100 puzzle levels were included, as well as 2, 500 user-submitted levels from the online service.

This puzzle doesn't have a 100 % winning strategy, so the question is: What is the best strategy?

The cash prize if a contestant solved the puzzle with no prizes on his / her side of the board was increased from $ 100 to $ 250.

If the contestant was able to solve the puzzle before time expired, the clock was stopped and he / she won $ 100.

The game features a total of 17 levels with 100 different puzzle rooms, nine boss rooms, and ten training rooms.

The team who correctly solved the master puzzle earned an additional 100 points, while an incorrect solution passed control to the other team.

Contestants were later awarded a prize for solving the puzzle, in addition to the 100 points.

Scoring in the second round doubled to 10 points per letter and 100 points for solving the puzzle.

It features 7 different characters from which the player can choose as well as 100 puzzle levels.

If a puzzle went completely unsolved, the value of that puzzle carried over to the next puzzle ( for example, if the second $ 100 puzzle was not solved, the next one would then be worth $ 350 instead of the normal $ 250 ).

Because the puzzles from the first round were only worth $ 100, a team had to win both their own $ 250 second round puzzle and their opponent's to reach a score of at least $ 500.

Each plate was a clue to a puzzle, and each one solved earned $ 100.
