The object of this Cookies for Grampy game is to make whole cookies using fractional pieces.
Press the <Start> button to display pieces of cookies. Use the mouse to drag the pieces onto the circle to make a complete cookie. When half or more of the cookie is made you may enter the exact remaining amount to complete the cookie.
When you run out of cookie pieces, the Cookie Making Machine dialog will let you enter the final amount to complete the cookie.
The timer starts after you drag the first piece onto the empty circle so it would be a good idea to plan your strategy before you start dragging. The timer stops when all the pieces are gone and the final cookie is complete.
After the cookie pieces are gone and the final cookie is complete, you may press the <New Pieces> button for more pieces. You may press the <Start> button to reset the minutes, seconds, and the number of cookies back to to 0.

Qualify as a CHAMPION COOKIE MAKER by achieving a score of more than six cookies per minute.
