Step

- Buy a plant spend coins or gems in the shop to add a plant to your collection.
- Place it in your garden drop it onto your plot so it starts fighting zombies on its own.
- Merge two matching plants put two of the same plant side by side to combine them into a more powerful version.
- Survive the wave let your plants do the fighting, collect the coins and gems that drop, then prepare for the next wave.

Merging efficiently
Tips
Merging is the main way to power up. If you feel stuck on a wave, that is your signal to merge the plants you already have.
- Collect multiples of the same plant rather than spreading coins across several different types.
- When your garden fills up, sell plants you no longer need to free space for merging.
- Work your way up from the weakest form — each merge moves you one step closer to the next tier.
Coins and gems
Table
Both currencies drop every time you defeat zombies, so battles are your main source of income for both.
| Coins | the main currency, used to buy standard plants. |
| Gems | the rarer currency, used for rare plants and special items. |
| Source for both | defeating zombies in any wave. |
Tougher enemies and bosses
Warn
As you clear waves and progress through worlds, ordinary zombies give way to significantly harder enemies and boss-level threats.
