Draw a square grid on the betting board that contains 100 boxes; 10 across and 10 down. Leave some space in the margins outside of the top and left side of the grid because you will need to write numbers there later. Make your boxes large enough for players to clearly write their names inside.
Fill up the boxes with participants. The game is one of chance and does not require any strategy or science, therefore the players should choose the boxes that feel are lucky for them. Fill up the entire board if possible; empty boxes mean there is a chance that there will be no winner. You can even turn the game into a fundraiser; sell a raffle ticket for each box, which can be turned in for a prize for the person who chooses the winning box.
Insert the numbers into the boxes. Write the numbers zero through nine on slips of paper and drop them into a hat. Pull out a slip and write that number above the box at the upper left-hand corner of the grid. Continue drawing and writing numbers until each column has a digit over top of it. Put the numbers back in the hat and follow the same process, this time writing the numbers along the left-hand side of the grid so that each row across has a number.
Determine your winner based on the numbers. The horizontal numbers are for team one and the vertical numbers are for team two, and thus these numbers declare the winner. For example, the final score of the game is 28 to 17. Find the column with the eight above it and then go down that column until you meet the box in the row that is marked by the seven. The person whose name appears in this box is your winner.
