Create or download an 11-by-11 square grid and print it on a sheet paper.
Allow participants to buy squares for $1 each. Players should initial or sign the squares that they purchase.
Place 10 small pieces of paper in a bag. Each paper has a number between one and 10.
Draw a number and write that number on the left most column in the second row.
Repeat step 4 for the rest of the numbers and go down a row each time. Fill the left-most column with randomly drawn numbers between one and 10. Leave the top left square blank.
Place the numbers back in the bag.
Repeat steps 4 and 5 using the first row and starting in the second column from the left until all but the left-most square in the top row are filled in.
Record the game’s score at the end of each quarter.
Look at the last digit of both scores at the end of each quarter. If the score is 17 to 14 then you use the numbers seven and four.
Find that spot on the grid. For 17 and 14, find the seventh row and move across to the fourth column.
See if someone has purchased that square. If so, they are a winner.
Do this for the score at the end of each quarter. There will be a maximum of four winners.
Count how many winners are in the pool.
Divide the amount of money collected for the pool by the number of winners. This is how much you pay to the winner from each quarter.
