Click the Scratch cat head to get coins. Go to the shop by clicking the house button. Buy upgrades at the shop by clicking the red button, it will only work when you have enough coins (You can check the number on the button). Once you're done doing stuff in the shop, click the house button to get back. Your goal is to get the most coins out of everyone.
