Twenty Numbers is a 'by the numbers' trivia game. In the main game you will be given 20 clues, each corresponding to a number on the board. Click on the number which you think each clue refers to. If wrong, the space will turn red. If correct, the space will turn green and display the money you've just won.

There are six values at the bottom of the screen, from $100 to $5,000. For each correct guess, you will move up a value, and the next question will be worth that amount. In addition, the correct number will be eliminated from the board. If you choose the wrong number, you will start back at the $100 mark and the number you chose will remain on the board.
