In "Papa's Donuteria," players run their own donut shop in the middle of an amusement park. The game features different types of customers and seasons. The seasons provide temporary upgrades, such as colored icing, cute sprinkles and cutout shapes for the donuts. After taking a customer's order, the player rolls the dough, cuts the shape, cooks the donut in oil, and decorates it with icing, fillings and other items.
"Plants VS. Zombies" pits plants against the living dead. Players use sunshine to purchase new plants for their yards to protect their house from incoming zombies. Higher levels of the game feature harder to kill zombies and new plants with upgraded defensive weapons.
