Knowing the pattern will allow you to begin at the pizza making machine
first before knowing the customer's order. This helps save a little
time.

Tip #2: Order of Upgrades. As you earn more profits, you can
upgrade your equipment. Players use a variety of upgrade sequences.
Here is the pattern that I use, but feel free to post what works for
you.

After step 1: No upgrade
After step 2: No upgrade
After step 3: Buy 2nd pizza maker
After step 4: Upgrade shoes
After step 5: Buy 2nd oven
After step 6. Buy 2nd topping station
After step 7: Buy 3rd pizza maker and upgrade 1st pizza maker
After step 8. Upgrade 1st oven
After step 9: Buy 3rd topping station and upgrade 1st topping station
After step 10: Upgrade shoes and Upgrade 2nd pizza maker

Then continue until all topping stations and pizza makers are upgraded. I don't usually make it past step 11.

Tip #3: You can cook multiple pizzas at once.Each
oven has the capacity to cook a single, whole pizza at a time. If
you're cooking a half pizza, you can add another half pizza or one
or two quarter pizzas to the same oven. If you're cooking a quarter
pizza, you can add up to three more quarter pizzas, or a half pizza and
a quarter pizza. It helps to have several pizzas in the oven at a time.
Make sure you plan for the whole pizza though so you don't waste
valuable time.


Tip #4: The bigger the pizza, the longer it takes. It takes
longer to make, cook and apply toppings to a whole pizza than it does to a smaller pizza. Thus, you may want to use your upgraded pizza makers,
topping stations and ovens on your larger pizzas. The same applies to
toppings. The more toppings, the longer it takes. use your upgraded
stations for these.

Tip #5: Don't skip the first level.
Round 1 is really easy -- just one quarter pizza with one topping. Although the game gives you the option of hitting a "skip" button to avoid the level altogether, it is not recommended to do this. The 55 dollars you earn from that initial customer will help you buy upgrades down the line.

Tip #6: Pizza "storage." There are times when you can save time by
transferring a pizza from one of your pizza makers to one of your
topping stations for "storage purposes." This can be a good time saver in later levels.

Tip #7: Stopping Berry. You can press the space bar to stop Berry at
any time during the game. So, if you give Berry a command that you
regret, rather than wait for her to reach her destination, you can
press the space bar and immediately give her a new command.

Tip #8: Quitting during the game.
If you mess up and are convinced that you
have no chance of passing a particular level, you can press the "Q" on
your keyboard to quit the level. It will still count as a loss, but you
won't have to look at all of the unhappy, demanding, steaming mad
customers.

Tip #9: Going out of order. You are not required to serve customers
or make pizzas in any particular order. Sometimes, you will make more
money by quickly serving a customer who is in the middle or in the back
of the line than you would if you served the first customer in line and
delayed serving another customer.

Tip #10: Sequencing your commands to Berry: When you give
Berry commands, a number appears on the item you click. Immediately
after giving one command, you can click on something else that you want
Berry to do once she finishes with the first command. You will see that
a number two or three will appear on your commands to show the order in
which you've told Berry to complete her tasks. You can chain commands
only if each command is possible when Berry gets to it. Thus, for example, Berry can't put a pizza in an oven that's already full, or top a pizza that's
currently being topped. If your chain of commands tells her to do one
of these things, the chain will break.

Thanks to Kodiak on WI for his useful guide to this game. It was an invaluable reference when I started playing. If you have any tips, please post them on this thread so we can all learn. Thanks and enjoy!

Wow excellent guide. There is a lot of information that I didn't know. I just causally play this game but I see that there is some real strategy to it.
