Click where you want the pizza slices shown in the center of the screen to appear on one of the 6 surrounding pans to build pizzas.
Click on one of the 6 pizza pans where the spaces associated with the slices in the center of the screen are open, repeat the process until you complete a pizza, when you complete a pizza that pan gets emptied along with pans on either side of it.
You score points each time you place a slice on a pan and points each time a pizza is completed.
The bottom of the screen shows the shape of the next piece coming up, as you complete levels the graphics change from pizza to lime to..
When building out pizzas try to focus on building on adjacent pans so if you complete one you get points from both. Try to concentrate your pieces as much as you can on as few as pans as possible to leave more openings for other pieces.
The game will not let you place pieces where there is not an empty spot on the pan for that slice, the game is not timed, but when you can no longer lay the piece shown the game is over.
