Below are the tips for selected levels.

?? LEVEL 1 | PERK GRIND

Best perk: Any

Best plant: Primal Peashooter (Stun + Knockback zombies), Moonflower (sun production)

Quite easy level in general, however, the "Produce Sun" objective makes the whole level unnecessarily long.

Do NOT let the zombies reach the flame trap, which can make you fail the "Produce Sun" objective easily due to killing zombies too fast.

?? LEVEL 2 | Conveyor

Very hard (if not impossible) level for low-level plants.

The given plants are too weak to destroy graves or defeat Z-mech at low levels!

Do it once, get the reward and forget about this level entirely.

?? LEVEL 3 | Beghouled Blitz

Best perk: Bass Blast Perk

Recommended upgrade path: Moonflower, Shadow Peashooter.

Find matches and complete the level as quickly as possible to prevent losing too much plants.

?? LEVEL 4 | PERK GRIND

Best perk: Any

Best plant: Pokra (handle ZCorpion), Draftodil (handle airborne zombies)

There are only 4 ZCorpion throughout the level.

A self-destructed ZCorpion is not a defeated ZCorpion!

Boingsetta / Spring Bean Plant Food can bounce zombies into the seas.

Use Plant Food wisely because they are very limited.

?? LEVEL 5

Best perk: Bass Blast Perk

Very hard for low-level plants (must use specific plants).

This level is RNG-based, even though it is a last stand level.

ZCorp Consultant enters the lawn through Sandstorm, which is the biggest threat throughout the level.

?? ZOMBOSS | Zombot Sphinx-inator - Ancient Egypt (with Roman Zombies - except ZCorpion and Medusa Zombie)

Zombie level: Lvl 1 / 4 / 7

Zomboss health bar: 5 / 7 / 9

Seed slot: 7 / 6 / 5

Locked plant: Imp Pear

Best perk: Bass Blast Perk, Heavy Watering Perk (for strats with Power Mints)

Three (3) gravestones regrow each time a new wave takes place.

The whole lawn can be spammed with gravestones (by Tomb Raiser) if not handled properly.

Appease-mint strategy performs exceptionally well in this level. Otherwise, use Ice Bloom, Boingsetta or Chilly Pepper to extinguish Explorer or Torchlight Zombie's flame.
