Quick answers
Frequently asked questions
Choose your next defense action, read the current game options and use these answers before spending.
What should I do first?
Roll plants, inspect what you receive and deploy plants to defend the base. Watch a wave before deciding whether to roll, merge or inspect a base upgrade next.
What does merging do?
The official description says merging makes plants stronger. Read the requirements and result shown in your current game before confirming.
How do I respond when enemies get through?
Watch where they pass the defense. Inspect your available plant and base upgrade choices, make one change and check the following wave.
Which plant or upgrade is best?
Compare the current information in your game with the defense problem you observed. This guide does not establish a universal best plant or purchase order.
Is RELEASE mentioned by the developer?
Yes. The official description checked on September 30 includes RELEASE. It does not give the reward, redemption steps or expiry, so the mention alone does not guarantee redemption.
Details still being mapped

- Wave counts, enemy rosters, timing, health values, rewards, and named world-boss details are not established by current sources.
- Merge requirements, resulting values, base upgrade costs, numerical effects, and an optimal order are not established.
- The official description does not state the RELEASE reward, redemption steps, case behavior, or expiry, so those details are omitted.
- Current sources does not establish an affiliation with or authorized comparison to Plants vs. Zombies or another third-party franchise, so no such details is allowed.
