As you answer each multiple-choice question correctly, they get more "eldritch", er, difficult, and are worth more money.

You can quit any time to keep the payout of the last question you answered correctly. If you answer one incorrectly, however, the game ends as well, and your winnings drop down to the nearest 'threshold' value (shown in red).

Unlike the show, there are no lifelines. Also, it is possible to cheat using your Back button or a search engine; but try playing 'clean' for a greater challenge.
