You can get puzzle pieces on three ways:

1. Daily Special Treasure Chest (awards you with one to three puzzle pieces of random plant, also have a rare chance to even give out the whole plant for free)

2. Daily Special Lottery (daily awards you some goodies, such as puzzle pieces of plants, their costumes, it also awards you with 50 gems weekly and even the monthly plants)

3. Beating levels (see the plants in the circles above some levels? With these levels you can get up to three puzzle pieces of the said plant daily, but everytime you repeat the level, the health of zombies increases)
