After all the players broke through the obstacles for ten levels, they started the three-star mode of pirate harbor. As the name implies, the three-star mode means to create three levels on the basis of the original level. According to the difficulty level, they are divided into "one star", "two stars" and "three stars". On the first day of the pirate harbor, the conditions for one star to pass are: not to plant on the moldy ground and not to lose any cart. These two also mean the reduction of the overall front and the absence of any backup measures in the game (the cart can not be lost, representing the loss of the last line of Defense).
1. After the game starts, according to the Convention of planting sunflowers, players can notice that there is a fault deck in this level, which means that only two attack plants can be planted in this line. While using potato mines against the first zombie, put the nuts on it. The next step is to plant pea shooters in response to the first wave of more common zombies.
2. Because this level will not appear such as hat zombies, iron bucket zombies and other capable zombies, so a row of pea shooters attack more than enough. When choosing plants in this level, you don't have to choose dart shooters. Frozen lettuce, nuts, potatoes, mines and peas are enough for this group of ordinary zombies.
3. At the end of the game, it is suggested that players add a row of pea shooters to deal with the zombie tide, and at the same time, they must reserve a cabbage pitcher to block completely. Zombies are easy to die in this level, so the effectiveness of cabbage pitcher is undoubtedly huge, and the collected energy beans can be used up in one go at the end of the game. The basic configuration of the game is a row of sunflowers, two rows of pea shooters, two to three nuts, frozen lettuce and potato mines, see the right time to use.
